Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application is a continuation and claims the benefit of
U.S. patent application Ser. No. 16/937,256, entitled "DETAILS OF
PHYSICAL UPLINK CONTROL CHANNEL (PUCCH) REPETITION WITH DIFFERENT
BEAMS," filed on Jul. 23, 2020, which itself claims the benefit of
U.S. Provisional Patent Application 62/878,698, entitled, "DETAILS
OF PUCCH REPETITION WITH DIFFERENT BEAMS," filed on Jul. 25, 2019,
which are expressly incorporated by reference herein in their
entirety.
BACKGROUND
Field
[0002] Aspects of the present disclosure relate generally to
wireless communication systems, and more particularly, to physical
uplink control channel (PUCCH) repetition.
Background
[0003] Wireless communication networks are widely deployed to
provide various communication services such as voice, video, packet
data, messaging, broadcast, and the like. These wireless networks
may be multiple-access networks capable of supporting multiple
users by sharing the available network resources. Such networks,
which are usually multiple access networks, support communications
for multiple users by sharing the available network resources. One
example of such a network is the Universal Terrestrial Radio Access
Network (UTRAN). The UTRAN is the radio access network (RAN)
defined as a part of the Universal Mobile Telecommunications System
(UMTS), a third generation (3G) mobile phone technology supported
by the 3rd Generation Partnership Project (3GPP). Examples of
multiple-access network formats include Code Division Multiple
Access (CDMA) networks, Time Division Multiple Access (TDMA)
networks, Frequency Division Multiple Access (FDMA) networks,
Orthogonal FDMA (OFDMA) networks, and Single-Carrier FDMA (SC-FDMA)
networks.
[0004] A wireless communication network may include a number of
base stations or node Bs that can support communication for a
number of user equipments (UEs). A UE may communicate with a base
station via downlink and uplink. The downlink (or forward link)
refers to the communication link from the base station to the UE,
and the uplink (or reverse link) refers to the communication link
from the UE to the base station.
[0005] A base station may transmit data and control information on
the downlink to a UE or may receive data and control information on
the uplink from the UE. On the downlink, a transmission from the
base station may encounter interference due to transmissions from
neighbor base stations or from other wireless radio frequency (RF)
transmitters. On the uplink, a transmission from the UE may
encounter interference from uplink transmissions of other UEs
communicating with the neighbor base stations or from other
wireless RF transmitters. This interference may degrade performance
on both the downlink and uplink.
[0006] As the demand for mobile broadband access continues to
increase, the possibilities of interference and congested networks
grows with more UEs accessing the long-range wireless communication
networks and more short-range wireless systems being deployed in
communities. Research and development continue to advance wireless
technologies not only to meet the growing demand for mobile
broadband access, but to advance and enhance the user experience
with mobile communications.
[0007] Physical uplink control channel (PUCCH) repetition in
different slots was developed and implemented in Rel. 15 for PUCCH
formats 1, 3, and 4. As implemented, the same
PUCCH-SpatialRelationInfo is used in all repetitions. Additionally,
a resource control configuration for a given PUCCH format provides
the number of repetitions using a respective number of slots
("nrofSlots"). Accordingly, the same PUCCH resource is used across
all the repetitions--i.e., for each slot. However, the approach
implemented in Rel. 15 for PUCCH repetitions lacks flexibility and
adaptability to account for changing network conditions.
SUMMARY

disclosure to provide a basic understanding of the discussed
technology. This summary is not an extensive overview of all
contemplated features of the disclosure, and is intended neither to

DETAILED DESCRIPTION
[0083] The detailed description set forth below, in connection with
the appended drawings, is intended as a description of various
configurations and is not intended to limit the scope of the
disclosure. Rather, the detailed description includes specific
details for the purpose of providing a thorough understanding of
the inventive subject matter. It will be apparent to those skilled
in the art that these specific details are not required in every
case and that, in some instances, well-known structures and
components are shown in block diagram form for clarity of
presentation.
[0084] This disclosure relates generally to providing or
participating in authorized shared access between two or more
wireless communications systems, also referred to as wireless
communications networks. In various embodiments, the techniques and
apparatus may be used for wireless communication networks such as
code division multiple access (CDMA) networks, time division
multiple access (TDMA) networks, frequency division multiple access
(FDMA) networks, orthogonal FDMA (OFDMA) networks, single-carrier
FDMA (SC-FDMA) networks, LTE networks, GSM networks, 5th Generation
(5G) or new radio (NR) networks, as well as other communications
networks. As described herein, the terms "networks" and "systems"
may be used interchangeably.
[0085] An OFDMA network may implement a radio technology such as
evolved UTRA (E-UTRA), IEEE 802.11, IEEE 802.16, IEEE 802.20,
flash-OFDM and the like. UTRA, E-UTRA, and Global System for Mobile
Communications (GSM) are part of universal mobile telecommunication
system (UMTS). In particular, long term evolution (LTE) is a
release of UMTS that uses E-UTRA. UTRA, E-UTRA, GSM, UMTS and LTE
are described in documents provided from an organization named "3rd
Generation Partnership Project" (3GPP), and cdma2000 is described
in documents from an organization named "3rd Generation Partnership
Project 2" (3GPP2). These various radio technologies and standards
are known or are being developed. For example, the 3rd Generation
Partnership Project (3GPP) is a collaboration between groups of
telecommunications associations that aims to define a globally
applicable third generation (3G) mobile phone specification. 3GPP
LTE is a 3GPP project which was aimed at improving the UMTS mobile
phone standard. The 3GPP may define specifications for the next
generation of mobile networks, mobile systems, and mobile devices.
The present disclosure is concerned with the evolution of wireless
technologies from LTE, 4G, 5G, NR, and beyond with shared access to
wireless spectrum between networks using a collection of new and
different radio access technologies or radio air interfaces.
[0086] In particular, 5G networks contemplate diverse deployments,
diverse spectrum, and diverse services and devices that may be
implemented using an OFDM-based unified, air interface. In order to
achieve these goals, further enhancements to LTE and LTE-A are
considered in addition to development of the new radio technology
for 5G NR networks. The 5G NR will be capable of scaling to provide
coverage (1) to a massive Internet of things (IoTs) with an
ultra-high density (e.g., .about.1M nodes/km.sup.2), ultra-low
complexity (e.g., .about.10s of bits/sec), ultra-low energy (e.g.,
.about.10+ years of battery life), and deep coverage with the
capability to reach challenging locations; (2) including
mission-critical control with strong security to safeguard
sensitive personal, financial, or classified information,
ultra-high reliability (e.g., .about.0.99.9999% reliability),
ultra-low latency (e.g., .about.1 ms), and users with wide ranges
of mobility or lack thereof; and (3) with enhanced mobile broadband
including extreme high capacity (e.g., .about.10 Tbps/km.sup.2),
extreme data rates (e.g., multi-Gbps rate, 100+ Mbps user
experienced rates), and deep awareness with advanced discovery and
optimizations.
[0087] The 5G NR may be implemented to use optimized OFDM-based
waveforms with scalable numerology and transmission time interval
(TTI); having a common, flexible framework to efficiently multiplex
services and features with a dynamic, low-latency time division
duplex (TDD)/frequency division duplex (FDD) design; and with
advanced wireless technologies, such as massive multiple input,
multiple output (MIMO), robust millimeter wave (mmWave)
transmissions, advanced channel coding, and device-centric
mobility. Scalability of the numerology in 5G NR, with scaling of
subcarrier spacing, may efficiently address operating diverse
services across diverse spectrum and diverse deployments. For
example, in various outdoor and macro coverage deployments of less
than 3 GHz FDD/TDD implementations, subcarrier spacing may occur
with 15 kHz, for example over 1, 5, 10, 20 MHz, and the like
bandwidth. For other various outdoor and small cell coverage
deployments of TDD greater than 3 GHz, subcarrier spacing may occur
with 30 kHz over 80/100 MHz bandwidth. For other various indoor
wideband implementations, using a TDD over the unlicensed portion
of the 5 GHz band, the subcarrier spacing may occur with 60 kHz
over a 160 MHz bandwidth. Finally, for various deployments
transmitting with mmWave components at a TDD of 28 GHz, subcarrier
spacing may occur with 120 kHz over a 500 MHz bandwidth.
[0088] The scalable numerology of the 5G NR facilitates scalable
TTI for diverse latency and quality of service (QoS) requirements.
For example, shorter TTI may be used for low latency and high
reliability, while longer TTI may be used for higher spectral
efficiency. The efficient multiplexing of long and short TTIs to
allow transmissions to start on symbol boundaries. 5G NR also
contemplates a self-contained integrated subframe design with
uplink/downlink scheduling information, data, and acknowledgement
in the same subframe. The self-contained integrated subframe
supports communications in unlicensed or contention-based shared
spectrum, adaptive uplink/downlink that may be flexibly configured
on a per-cell basis to dynamically switch between uplink and
downlink to meet the current traffic needs.
[0089] Various other aspects and features of the disclosure are
further described below. It should be apparent that the teachings
herein may be embodied in a wide variety of forms and that any
specific structure, function, or both being disclosed herein is
merely representative and not limiting. Based on the teachings
herein one of an ordinary level of skill in the art should
appreciate that an aspect disclosed herein may be implemented
independently of any other aspects and that two or more of these
aspects may be combined in various ways. For example, an apparatus
may be implemented or a method may be practiced using any number of
the aspects set forth herein. In addition, such an apparatus may be
implemented or such a method may be practiced using other
structure, functionality, or structure and functionality in
addition to or other than one or more of the aspects set forth
herein. For example, a method may be implemented as part of a
system, device, apparatus, or as instructions stored on a computer
readable medium for execution on a processor or computer.
Furthermore, an aspect may include at least one element of a
claim.
[0090] FIG. 1 is a block diagram illustrating 5G network 100
including various base stations and UEs configured according to
aspects of the present disclosure. The 5G network 100 includes a
number of base stations 105 and other network entities. A base
station may be a station that communicates with the UEs and may
also be referred to as an evolved node B (eNB), a next generation
eNB (gNB), an access point, and the like. Each base station 105 may
provide communication coverage for a particular geographic area. In
3GPP, the term "cell" can refer to this particular geographic
coverage area of a base station or a base station subsystem serving
the coverage area, depending on the context in which the term is
used.
[0091] A base station may provide communication coverage for a
macro cell or a small cell, such as a pico cell or a femto cell, or
other types of cell. A macro cell generally covers a relatively
large geographic area (e.g., several kilometers in radius) and may
allow unrestricted access by UEs with service subscriptions with
the network provider. A small cell, such as a pico cell, would
generally cover a relatively smaller geographic area and may allow
unrestricted access by UEs with service subscriptions with the
network provider. A small cell, such as a femto cell, would also
generally cover a relatively small geographic area (e.g., a home)
and, in addition to unrestricted access, may also provide
restricted access by UEs having an association with the femto cell
(e.g., UEs in a closed subscriber group (CSG), UEs for users in the
home, and the like). A base station for a macro cell may be
referred to as a macro base station. A base station for a small
cell may be referred to as a small cell base station, a pico base
station, a femto base station or a home base station. In the
example shown in FIG. 1, the base stations 105d and 105e are
regular macro base stations, while base stations 105a-105c are
macro base stations enabled with one of 3 dimension (3D), full
dimension (FD), or massive MIMO. Base stations 105a-105c take
advantage of their higher dimension MIMO capabilities to exploit 3D
beamforming in both elevation and azimuth beamforming to increase
coverage and capacity. Base station 105f is a small cell base
station which may be a home node or portable access point. A base
station may support one or multiple (e.g., two, three, four, and
the like) cells.
[0092] The 5G network 100 may support synchronous or asynchronous
operation. For synchronous operation, the base stations may have
similar frame timing, and transmissions from different base
stations may be approximately aligned in time. For asynchronous
operation, the base stations may have different frame timing, and
transmissions from different base stations may not be aligned in
time.
[0093] The UEs 115 are dispersed throughout the wireless network
100, and each UE may be stationary or mobile. A UE may also be
referred to as a terminal, a mobile station, a subscriber unit, a
station, or the like. A UE may be a cellular phone, a personal
digital assistant (PDA), a wireless modem, a wireless communication
device, a handheld device, a tablet computer, a laptop computer, a
cordless phone, a wireless local loop (WLL) station, or the like.
In one aspect, a UE may be a device that includes a Universal
Integrated Circuit Card (UICC). In another aspect, a UE may be a
device that does not include a UICC. In some aspects, UEs that do
not include UICCs may also be referred to as internet of everything
(IoE) or internet of things (IoT) devices. UEs 115a-115d are
examples of mobile smart phone-type devices accessing 5G network
100 A UE may also be a machine specifically configured for
connected communication, including machine type communication
(MTC), enhanced MTC (eMTC), narrowband IoT (NB-IoT) and the like.
UEs 115e-115k are examples of various machines configured for
communication that access 5G network 100. A UE may be able to
communicate with any type of the base stations, whether macro base
station, small cell, or the like. In FIG. 1, a lightning bolt
(e.g., communication links) indicates wireless transmissions
between a UE and a serving base station, which is a base station
designated to serve the UE on the downlink or uplink, or desired
transmission between base stations, and backhaul transmissions
between base stations.
[0094] In operation at 5G network 100, base stations 105a-105c
serve UEs 115a and 115b using 3D beamforming and coordinated
spatial techniques, such as coordinated multipoint (CoMP) or
multi-connectivity. Macro base station 105d performs backhaul
communications with base stations 105a-105c, as well as small cell,
base station 105f. Macro base station 105d also transmits multicast
services which are subscribed to and received by UEs 115c and 115d.
Such multicast services may include mobile television or stream
video, or may include other services for providing community
information, such as weather emergencies or alerts, such as Amber
alerts or gray alerts.
[0095] 5G network 100 also support mission critical communications
with ultra-reliable and redundant links for mission critical
devices, such UE 115e, which is a drone. Redundant communication
links with UE 115e include from macro base stations 105d and 105e,
as well as small cell base station 105f. Other machine type
devices, such as UE 115f (thermometer), UE 115g (smart meter), and
UE 115h (wearable device) may communicate through 5G network 100
either directly with base stations, such as small cell base station
105f, and macro base station 105e, or in multi-hop configurations
by communicating with another user device which relays its
information to the network, such as UE 115f communicating
temperature measurement information to the smart meter, UE 115g,
which is then reported to the network through small cell base
station 105f. 5G network 100 may also provide additional network
efficiency through dynamic, low-latency TDD/FDD communications,
such as in a vehicle-to-vehicle (V2V) mesh network between UEs
115i-115k communicating with macro base station 105e.
[0096] FIG. 2 shows a block diagram of a design of a base station
105 and a UE 115, which may be one of the base station and one of
the UEs in FIG. 1. At the base station 105, a transmit processor
220 may receive data from a data source 212 and control information
from a controller/processor 240. The control information may be for
the PBCH, PCFICH, PHICH, PDCCH, EPDCCH, MPDCCH etc. The data may be
for the PDSCH, etc. The transmit processor 220 may process (e.g.,
encode and symbol map) the data and control information to obtain
data symbols and control symbols, respectively. The transmit
processor 220 may also generate reference symbols, e.g., for the
PSS, SSS, and cell-specific reference signal. A transmit (TX)
multiple-input multiple-output (MIMO) processor 230 may perform
spatial processing (e.g., precoding) on the data symbols, the
control symbols, or the reference symbols, if applicable, and may
provide output symbol streams to the modulators (MODs) 232a through
232t. Each modulator 232 may process a respective output symbol
stream (e.g., for OFDM, etc.) to obtain an output sample stream.
Each modulator 232 may further process (e.g., convert to analog,
amplify, filter, and upconvert) the output sample stream to obtain
a downlink signal. Downlink signals from modulators 232a through
232t may be transmitted via the antennas 234a through 234t,
respectively.
[0097] At the UE 115, the antennas 252a through 252r may receive
the downlink signals from the base station 105 and may provide
received signals to the demodulators (DEMODs) 254a through 254r,
respectively. Each demodulator 254 may condition (e.g., filter,
amplify, downconvert, and digitize) a respective received signal to
obtain input samples. Each demodulator 254 may further process the
input samples (e.g., for OFDM, etc.) to obtain received symbols. A
MIMO detector 256 may obtain received symbols from all the
demodulators 254a through 254r, perform MIMO detection on the
received symbols if applicable, and provide detected symbols. A
receive processor 258 may process (e.g., demodulate, deinterleave,
and decode) the detected symbols, provide decoded data for the UE
115 to a data sink 260, and provide decoded control information to
a controller/processor 280.
[0098] On the uplink, at the UE 115, a transmit processor 264 may
receive and process data (e.g., for the PUSCH) from a data source
262 and control information (e.g., for the PUCCH) from the
controller/processor 280. The transmit processor 264 may also
generate reference symbols for a reference signal. The symbols from
the transmit processor 264 may be precoded by a TX MIMO processor
266 if applicable, further processed by the modulators 254a through
254r (e.g., for SC-FDM, etc.), and transmitted to the base station
105. At the base station 105, the uplink signals from the UE 115
may be received by the antennas 234, processed by the demodulators
232, detected by a MIMO detector 236 if applicable, and further
processed by a receive processor 238 to obtain decoded data and
control information sent by the UE 115. The processor 238 may
provide the decoded data to a data sink 239 and the decoded control
information to the controller/processor 240.
[0099] The controllers/processors 240 and 280 may direct the
operation at the base station 105 and the UE 115, respectively. The
controller/processor 240 or other processors and modules at the
base station 105 may perform or direct the execution of various
processes for the techniques described herein. The
controllers/processor 280 or other processors and modules at the UE
115 may also perform or direct the execution of the functional
blocks illustrated in FIGS. 8-19, or other processes for the
techniques described herein. The memories 242 and 282 may store
data and program codes for the base station 105 and the UE 115,
respectively. A scheduler 244 may schedule UEs for data
transmission on the downlink or uplink.
[0100] Wireless communications systems operated by different
network operating entities (e.g., network operators) may share
spectrum. In some instances, a network operating entity may be
configured to use an entirety of a designated shared spectrum for
at least a period of time before another network operating entity
uses the entirety of the designated shared spectrum for a different
period of time. Thus, in order to allow network operating entities
use of the full designated shared spectrum, and in order to
mitigate interfering communications between the different network
operating entities, certain resources (e.g., time) may be
partitioned and allocated to the different network operating
entities for certain types of communication.
[0101] For example, a network operating entity may be allocated
certain time resources reserved for exclusive communication by the
network operating entity using the entirety of the shared spectrum.
The network operating entity may also be allocated other time
resources where the entity is given priority over other network
operating entities to communicate using the shared spectrum. These
time resources, prioritized for use by the network operating
entity, may be utilized by other network operating entities on an
opportunistic basis if the prioritized network operating entity
does not utilize the resources. Additional time resources may be
allocated for any network operator to use on an opportunistic
basis.
[0102] Access to the shared spectrum and the arbitration of time
resources among different network operating entities may be
centrally controlled by a separate entity, autonomously determined
by a predefined arbitration scheme, or dynamically determined based
on interactions between wireless nodes of the network
operators.
[0103] In some cases, UE 115 and base station 105 of the 5g network
100 (in FIG. 1) may operate in a shared radio frequency spectrum
band, which may include licensed or unlicensed (e.g.,
contention-based) frequency spectrum. In an unlicensed frequency
portion of the shared radio frequency spectrum band, UEs 115 or
base stations 105 may traditionally perform a medium-sensing
procedure to contend for access to the frequency spectrum. For
example, UE 115 or base station 105 may perform a listen before
talk (LBT) procedure such as a clear channel assessment (CCA) prior
to communicating in order to determine whether the shared channel
is available. A CCA may include an energy detection procedure to
determine whether there are any other active transmissions. For
example, a device may infer that a change in a received signal
strength indicator (RSSI) of a power meter indicates that a channel
is occupied. Specifically, signal power that is concentrated in a
certain bandwidth and exceeds a predetermined noise floor may
indicate another wireless transmitter. A CCA also may include
detection of specific sequences that indicate use of the channel.
For example, another device may transmit a specific preamble prior
to transmitting a data sequence. In some cases, an LBT procedure
may include a wireless node adjusting its own backoff window based
on the amount of energy detected on a channel or the
acknowledge/negative-acknowledge (ACK/NACK) feedback for its own
transmitted packets as a proxy for collisions.
[0104] Use of a medium-sensing procedure to contend for access to
an unlicensed shared spectrum may result in communication
inefficiencies. This may be particularly evident when multiple
network operating entities (e.g., network operators) are attempting
to access a shared resource. In the 5G network 100, base stations
105 and UEs 115 may be operated by the same or different network
operating entities. In some examples, an individual base station
105 or UE 115 may be operated by more than one network operating
entity. In other examples, each base station 105 and UE 115 may be
operated by a single network operating entity. Requiring each base
station 105 and UE 115 of different network operating entities to
contend for shared resources may result in increased signaling
overhead and communication latency.
[0105] FIG. 3 illustrates an example of a wireless communications
system 300 that supports physical uplink control channel (PUCCH)
repetition in accordance with aspects of the present disclosure. In
some examples, wireless communications system 300 may implement
aspects of wireless communication system 100. For example, wireless
communications system 300 may include UE 115 and base station 105.
Although one UE and one base station are illustrated, in other
implementations, wireless communications system 300 may include
multiple UEs 115, multiple base stations 105, or both. For example,
base station 105 (e.g., a network entity) may include or correspond
to a first base station (e.g., a first network entity), such as an
eNB, and a second base station (e.g., a second network entity),
such as a gNB.
[0106] Base station 105 includes processor 302, memory 304,
transmitter 310, receiver 312, and a radio resource control (RRC)
configuration generator 314. Processor 302 may be configured to
execute instructions stores at memory 304 to perform the operations
described herein. In some implementations, processor 302 includes
or corresponds to controller/processor 240, and memory 304 includes
or corresponds to memory 242. Memory 304 may also be configured to
store UE information 320, beam information 322, one or more
configuration settings 324, mapping information 326, and
transmission configuration indicator (TCI) state information 328,
as further described herein.
[0107] For example, the UE information 320 may indicate one or more
UEs in communication with base station 105. In some
implementations, UE information 320 may include or indicate, for a
UE, a PUCCH repetition mode (e.g., scheme), RRC configuration
information (e.g., 324), one or more beams (e.g., 322), such as an
activated beam for a PUCCH source, one or more TCI states, or a
combination thereof.
[0108] Beam information 322 may identify one or more beams or a set
of indices corresponding to one or more beams. Configuration
settings 324 may include one or more settings for PUCCH repetition,
such as a repetition mode. To illustrate, configuration settings
324 may include one or more PUCCH resources. In some
implementations, configuration settings 324 may include a PUCCH
resource set, and each set can include up to eight PUCCH resources,
as an illustrative, non-limiting example. As an exception, a first
(e.g., initial) set may include up to thirty-two PUCCH resources
while other sets may only include up to eight PUCCH resources.
Additionally, or alternatively, and one or more sets can be
configured (e.g., via RRC configuration). For example, up to four
sets may be configured (e.g., via RRC configuration), as an
illustrative, non-limiting example. Which set to use may depend on
the payload size of uplink control information (UCI).
[0109] For a PUCCH resource, a set of RBs/symbols and a PUCCH
format are indicated and configured per PUCCH resource (e.g., via
RRC configuration). For example, PUCCH spatial relation information
("PUCCH-SpatialRelationInfo") may be used indicate the beam to use
for a PUCCH resource. Additionally, or alternatively, a set of
indices (corresponding to a set of one or more beams--e.g., each
index can point to SSB/CSI-RS/SRS for reference signal) is
configured by RRC for all PUCCH resources. For a given PUCCH
resource, one index (e.g., beam) can be activated by MAC-CE. In
some implementations, power control parameters are also included as
part of PUCCH-SpatialRelationInfo.
[0110] In some implementations, memory 304 may include scheduling
information for PUCCH included in the downlink control information
(DCI) (DCI format 1_0 or 1_1). The memory 304 may include or track
a PDSCH-to-HARQ_feedback timing indicator field (a.k.a. K1 value).
The K1 value may include an index pointing a value of DL data to UL
A/N in unit of slots from a configured set or a default set, such
as {1, 2, 3, 4, 5, 6, 7, 8}. The index may indicate or be used to
determine which slot a HARQ-A for the scheduled PDSCH is to be to
be transmitted on PUCCH. Additionally, configuration settings 324
may include a PUCCH resource indicator (PRI). The PRI may include
an index that is used to determine a PUCCH resource within a PUCCH
resource set. In some implementations, a PRI in a last DCI is
considered (among all the DCIs that have a value of K1 indicating a
same slot for PUCCH transmission).
[0111] Mapping information 326 information may include one or more
data structures for mapping a PRI field codepoint to one or more
interpreted PRI values, as described further herein at least with
reference to FIG. 5. TCI state information 328 may a TCI code point
which, in DCI, can correspond to one or two TCI states.
[0112] Transmitter 310 is configured to transmit data to one or
more other devices, and receiver 312 is configured to receive data
from one or more other devices. For example, transmitter 310 may
transmit data, and receiver 312 may receive data, via a network,
such as a wired network, a wireless network, or a combination
thereof. For example, base station 105 may be configured to
transmit or receive data via a direct device-to-device connection,
a local area network (LAN), a wide area network (WAN), a
modem-to-modem connection, the Internet, intranet, extranet, cable
transmission system, cellular communication network, any
combination of the above, or any other communications network now
known or later developed within which permits two or more
electronic devices to communicate. In some implementations,
transmitter 310 and receiver 312 may be replaced with a
transceiver. Additionally, or alternatively, transmitter 310,
receiver, 312, or both may include or correspond to one or more
components of base station 105 described with reference to FIG.
2.
[0113] RRC configuration generator 314 is configured to generate
the one or more RRC configuration settings. For example, RRC
configuration generator 314 may generate one or more RRC
configuration settings based on UE information 320, beam
information 322, configuration setting 324, mapping information
326, TCI state information 328, or a combination thereof.
[0114] UE 115 includes processor 330, memory 332, transmitter 334,
receiver 336, a settings identifier 337, a resource selector 338,
and a beam generator 339. Processor 330 may be configured to
execute instructions stored at memory 332 to perform the operations
described herein. In some implementations, processor 330 includes
or corresponds to controller/processor 280, and memory 332 includes
or corresponds to memory 282. Memory 332 may also be configured to
store one or more repetition settings 340 and mapping information
326. The one or more repetition settings 340 may be used by UE 115
to perform PUCCH repetition one or more slot position, such as one
or more slots, one or more sub-slots, or a combination thereof. In
some implementations, the repetition settings 340 may include or
indicate one or more repetition modes.
[0115] Transmitter 334 is configured to transmit data to one or
more other devices, and receiver 336 is configured to receive data
from one or more other devices. For example, transmitter 334 may
transmit data, and receiver 336 may receive data, via a network,
such as a wired network, a wireless network, or a combination
thereof. For example, UE 115 may be configured to transmit or
receive data via a direct device-to-device connection, a LAN, a
WAN, a modem-to-modem connection, the Internet, intranet, extranet,
cable transmission system, cellular communication network, any
combination of the above, or any other communications network now
known or later developed within which permits two or more
electronic devices to communicate. In some implementations,
transmitter 334 and receiver 336 may be replaced with a
transceiver. Additionally, or alternatively, transmitter 334,
receiver, 336, or both may include or correspond to one or more
components of UE 115 described with reference to FIG. 2.
[0116] Setting(s) identifier 337 may receive one or more messages
from base station 105 and determine the one or more repetition
settings 340, as described herein. Resource selector 338 is
configure to select one or more PUCCH resources based on the one or
more repetition settings 340. Beam generator 339 is configured to
generate or use one or more beams based on the one or more
repetition settings.
[0117] During operation of wireless communications system 300, base
station 105 may send a repetition indicator 360 to UE 115.
Repetition indicator 360 may indicate whether or not UE 115 is to
perform PUCCH repetition, whether UE 115 is to perform a single
repetition per slot position or multiple repetitions for a slot
position, a PUCCH repetition mode (e.g., a PUCCH repetition
scheme), or a combination thereof. In some implementations, the
repetition indicator 360 may indicate a repetition mode of the UE
115.
[0118] Base station 105 may send a first message 361 to UE 115.
First message 361 may include or indicate UE information 320, beam
information 322, configuration settings 324, TCI state information
328, or a combination thereof. In some implementations, first
message 361 may include or correspond to repetition indicator 360.
First message 361 may include a RRC (e.g., one or more RRCs), a
DCI, or a MAC-CE, as illustrative, non-limiting examples. In some
implementations, first message 361 includes one or more RCCs
generated by RRC configuration generator 314. For example, RRC
configuration generator 314 may generate a first RRC for
PUCCH--SpatialRelationInfo that indicates a set of indices for one
or more resources (e.g., one or more PUCCH resources). As another
example, RRC configuration generator 314 may generate a second RRC
for PUCCH-FormatConfig that indicates a number of slots (e.g., a
value of a "nrofSlots" field). As another example, RRC
configuration generator 314 may generate a third RRC for
PUCCH-Config (in Rel. 15) that indicates
"spatialRelationInfoToAddModList" for all PUCCH resources. It is
noted that the second RRC (for PUCCH-FormatConfig (together with
"nrofSlots")) may be different from the third RRC (for PUCCH-Config
(in Rel. 15)) that indicates "spatialRelationInfoToAddModList" for
all PUCCH resources.
[0119] UE 115 receives repetition indicator 360, first message 361,
or both, and settings identifier 337 processes the repetition
indicator 360, first message 361, or both to determine repetition
settings 340 (e.g., PUCCH repetition settings). For example,
settings identifier 337 may process the repetition indicator 360,
first message 361, or both, according to a repetition mode (e.g., a
repetition scheme), such as a selected mode of multiple repetition
modes. In some implementations, the mode may be indicated by or
selected based on repetition indicator 360. After repetition
settings 340 are determined, UE 115 may perform repetition--e.g.,
transmit one or more PUCCH repetitions--based on the repetition
settings 340. For example, resource selector 338 may select, based
on repetition settings 340, one or more resources, such as one or
more PUCCH resources. Additionally, or alternatively, beam
generator 339 may select, based on repetition settings 340, one or
more beams. To illustrate, resource selector 338 may select a first
resource (e.g., a first PUCCH resource) for a first repetition 362,
and beam generator 339 may select a first beam for the first
resource. As another example, resource selector 338 may select a
second resource (e.g., a second PUCCH resource) for a second
repetition 363, and beam generator 339 may select a second beam
(different from the first beam) for the second resource.
[0120] UE 115 transmits the first repetition 362, the second
repetition 363, or both, based on the repetition settings 340. To
illustrate, UE 115 may transmit first repetition 362 and second
repetition during one or more slot positions. The one or more slot
positions may include or correspond to one or more slots, one or
more sub-slots, or a combination thereof. As an example, first
repetition 362 (for a first resource) is transmitted using a first
beam of multiple beams during a first slot position and second
repetition (for a second resource) is transmitting using a second
beam of multiple beams during a second slot positions. As another
example, first repetition 362 (for a first resource) is transmitted
using a first beam of multiple beams during a first slot position
and second repetition (for a second resource) is transmitted using
a second beam of multiple beams during the first slot
positions.
[0121] Base station 105 may receive first repetition 362, second
repetition 363, or both. Base station 105 may process first
repetition 362, second repetition 363, or both, based at least on
configuration settings 325.
[0122] In some implementations, UE 115 is configured with PUCCH
repetition through nrofSlots for a PUCCH format, and a PUCCH
resource is used. In such implementations, UE 115 may not use the
activated PUCCH-SpatialRelationInfo for that PUCCH resource.
[0123] To illustrate, according to a first mode of operation (e.g.,
a first scheme or a first option), UE 115 (e.g., 337) identifies a
set of indices configured by RRC for PUCCH-SpatialRelationInfo to
be used (configured in IE PUCCH-Config for all the PUCCH resources
in a BWP). During a first slot position, UE 115 uses a first beam
(e.g., a lowest ID: PUCCH-SpatialRelationInfold) to transmit first
repetition 362; during a second slot position, UE uses a second
beam (e.g., a next ID) to transmit second repetition 363; and so
on. In some implementations, UE 115 selects between the first
option and Rel. 15 behavior in which each repetition is sent using
the same beam.
[0124] In some implementations of the first option, the first
repetition 362 (e.g., an initial transmitted repetition), may use
the activated PUCCH-SpatialRelationInfo for the resource (e.g., the
PUCCH resource) that is used. The activated
PUCCH-SpatialRelationInfo for the resource may be indicated in a
MAC-CE. For one or more remaining repetitions (e.g., repetition(s)
following the initial transmitted repetition), the set of indices
configured by RRC for PUCCH-SpatialRelationInfo may be used.
[0125] Referring to FIG. 4, an example of the first option is shown
and generally designated 400. Example 400 shows multiple slot
positions, such as a first slot position 430 (e.g., Slot
Position_0), a second slot position 431 (e.g., Slot Position_1), a
third slot position 432 (e.g., Slot Position_2), and a fourth slot
position 433 (e.g., Slot Position_3). Although four slot positions
are shown, this is not to be considered limiting and fewer than or
more than four slot positions may be present. A slot position may
include a slot (e.g., an entirety of a slot) or a sub-slot. As an
example of sub-slots, each of the first slot position 430 and
second slot position 431 may be sub-slots of the same slot.
[0126] As shown in FIG. 4, a number of slot positions is equal to
four. For example, in some implementations, nrofSlots (or
"nrofSubslots") is equal to four. With reference to example 400, in
PUCCH-Config, "spatialRelationInfoToAddModList" contains three
beams (IDs=0, 1, 2), but for pucch-ResourceId=x, beam_2 (i.e.
PUCCH-SpatialRelationInfold=2) is activated through MAC-CE. Stated
in another manner, three beams are available for all resources
(e.g., PUCCH resources) and, for a resource x, beam_2 is activated
based on a MAC-CE. As shown in FIG. 4, the three beam include a
first beam 440 (e.g., beam_0), a second beam 441 (e.g., beam_1),
and a third beam 442 (e.g., beam_2). In FIG. 4, repetition in the
same resource (e.g., the same PUCCH resource)--i.e., resource x--is
shown. According to the first mode, first slot position 430 uses
third beam 442 (e.g., beam_2) for repetition because third beam 442
(e.g., beam_2) is the activated beam for resource x based on the
MAC-CE. After the first slot position 430, the set of three beams
are used (e.g., cycled through) for the remaining slot positions.
To illustrate, for repetition of resource x, first beam 440 (e.g.,
beam_0) is used for second slot position 431; second beam 441
(e.g., beam_1) is used for third slot position 431; and third beam
442 (e.g., beam_2) is used for fourth slot position 443.
[0127] As shown in FIG. 4, for the remaining repetitions (after the
initial repetition), the beam (e.g., third beam 442 (e.g.,
beam_2)-- the activated beam) for the initial slot position is used
again in the set of beams (440, 441, 442). In other
implementations, the beam (e.g., third beam 442 (e.g., beam_2)--
the activated beam) for the initial slot position may not be used
again for the remaining repetitions (after the initial repetition).
In such an implementation, first beam 440 (e.g., beam_0) is used
for second slot position 431; second beam 441 (e.g., beam_1) is
used for third slot position 432; and first beam 440 (e.g., beam_0)
is used for fourth slot position 443. It is noted that if a number
of beams in PUCCH-SpatialRelationInfold is less than a number of
slot positions (e.g., "nrofSlots" or "nrofsubSlots"), after going
through the set, the beams available for use are cycled through one
or more times, as needed, until the number of slot positions is
completed.
[0128] According to a second mode of operation (e.g., a second
scheme or a second option), UE 115 (e.g., 337) identifies a set of
one or more beams (e.g., a set of PUCCH-SpatialRelationInfold for
repetition beams) based on or using a second RRC for
PUCCH-FormatConfig. For example, in the second mode, a number of
slot positions and a set of beams for repetition may be defined by
PUCCH-FormatConfig for each of one or more formats. In some
implementations, the set of beams can have a same number of beams
as number of slot positions-- i.e., a one-to-one correspondence
between beams and slot positions. It is noted that if a number of
beams in PUCCH-SpatialRelationInfold is less than a number of slot
positions (e.g., "nrofSlots" or "nrofsubSlots"), after going
through the set, the beams available for use are cycled through one
or more times, as needed, until the number of slot positions is
completed. In some implementations of the second mode, if the set
of beams includes a single beam, the resource (e.g., the PUCCH
resource) may switch to operation according to Rel. 15 in which,
for the resource, the same beam is used for repetition for each
slot position.
[0129] It is noted that each of the first mode and the second mode
may be used for slots (inter-slot repetition) and subslots
(intra-slot repetition). For example, a set of beams may be cycled
through on a per slot basis or on a per subslot basis. As another
example, when a set of slot positions includes two or more slots
each with multiple subslots, the set of beams may be cycled through
per subslot. As another example, when a set of slot positions
includes two or more slots each with multiple subslots, the set of
beams may be cycled through per slot, where a beam is used for
multiple subslots for its correspond slot.
[0130] In some implementations, UE 115 may transmit, for a PUCCH
resource, a first PUCCH repetition (e.g., 362) for a first slot
position and a second PUCCH repetition (e.g., 363) for a second
slot position. For example, the first PUCCH repetition may be
transmitted using a second beam of multiple beams for the first
slot position of the multiple slot positions. The multiple slot
positions may include multiple slots or multiple sub-slots of a
slot. In some implementations, such as when UE 115 is configured
according to the first mode, UE 115 receives an RRC configuration
(e.g., 361) including a PUCCH resource. The UE 115 may also
identify a set of indices for one or more PUCCH resources. Each
index of the set of indices corresponding to a different beam of
multiple beams. For example, UE 115 (e.g., 337) identifies a set of
indices configured by RRC for PUCCH-SpatialRelationInfo to be used
(configured in IE PUCCH-Config for all the PUCCH resources in a
BWP). Alternatively, in other implementations, such as when UE 115
is configured according to the second mode, UE 115 may identify a
set of indices for one PUCCH resource (e.g., a single resource),
where each index of the set of indices corresponding to a different
beam of multiple beams. For example, UE 115 may identify the set of
indices defined by PUCCH-FormatConfig for each of one or more
formats.
[0131] According to a third mode of operation (e.g., a third scheme
or a third option), UE 115 may identify one or more resources
(e.g., PUCCH resources) based on PRI field codepoint in a DCI
(e.g., 361). For example, the PRI field codepoint may indicate
(e.g., point to) one PRI value or two PRI values. A PRI value may
indicate a PUCCH resource within a PUCCH resource set. The PRI
field codepoint may be mapped to one or more "interpreted" PRI
values using mapping information 326. The mapping between PRI field
codepoint in the DCI and the one or more interpreted PRI values can
be configured based on or responsive to repetition indicator 360 or
based on first message 361, such as responsive to an RRC
configuration or a MAC-CE. When multiple PRI values are
interpreted, multiple resources (e.g., PUCCH resources) may be
identified for repetition during a slot position. For example, UE
115 may use a first PUCCH resource of the multiple PUCCH resources
to transmit a first PUCCH repetition (e.g., 362) of the multiple
PUCCH repetitions within a slot position and use a second PUCCH
resource of the multiple PUCCH resources to transmit, a second
PUCCH repetition (e.g., 363) of the multiple PUCCH repetitions
within the same slot position (e.g., slot or subslot).
[0132] Referring to FIG. 5, an example of a data structure for
mapping a PRI field codepoint 502 to one or more interpreted PRI
values 520 is shown and designated 500. Each PRI field codepoint is
listed as an integer with a corresponding binary representation in
a parenthetical. As shown, for the case of one interpreted PRI
value or two interpreted PRI values, the first PRI value is the
same as the codepoint in the DCI. Accordingly, in such an
implementation, only the second interpreted PRI is configured
through RRC or activated through MAC-CE. Additionally, it is noted
that the second interpreted PRI for some of the codepoints can be
"empty", i.e., that codepoint only indicates one PRI value. When
there are two interpreted PRI values, the corresponding PUCCH
resources can have different MAC-CE activated
PUCCH-SpatialRelationInfo's. For example, the first interpreted
value corresponds to a first PUCCH resource using a first beam and
the second interpreted value corresponds to a second PUCCH resource
using a second beam. In other implementations, the first PRI value
is different from the codepoint in the DCI, and the first
interpreted value is configured through RRC or activated through
MAC-CE and the second interpreted value is configured through RRC
or activated through MAC-CE. Although data structure 500 has been
described as mapping a PRI field codepoint to one or two
interpreted PRI values, in other implementations, the data
structure 500 may be configured to map the PRI field codepoint to
more than two interpreted PRI values.
[0133] According to a fourth mode of operation (e.g., a fourth
scheme or a fourth option), UE 115 also uses PRI field codepoints
for determining repetition (e.g., PUCCH repetition). In some
implementations, the fourth mode and the third mode are part of the
same mode of operation. During the fourth mode, the UE 115 receives
from a network (e.g., base station 105) a DCI scheduling PDSCH and
a PRI field can be used indicate whether to use two PUCCH resources
to repeat the PUCCH content (HARQ-Ack codebook along with other
UCIs in the case of UCI multiplexing). For example, the DCI (e.g.,
361) may include a Downlink (DL) DCI scheduling a Physical Downlink
Shared Channel (PDSCH), and the PUCCH repetition includes a Hybrid
Automatic Repeat Request (HARQ)-ACK codebook.
[0134] Referring to FIG. 6, an example of the fourth mode is shown
and designated 600. As shown, the example includes slot positions
430-433. During each of the slot positions 430-432, a DCI and data
are communicated. For example, during first slot position 430, a
first DCI 610 and data 616 are communication; during second slot
position 431, a second DCI 620 and second data 626; and during
third slot position 432, third DCI 630 and third data is
communicated. Each DCI may have a correspond K1 value and may
indicate one or more PRI values 624. For example, first DCI 610
includes a first K1 value 612 (e.g., K1=3) and indicates a first
set of PRI values 614 (e.g., PRI: a, b); second DCI 620 includes a
second K1 value 622 (e.g., K1=2) and indicates a second set of PRI
values 624 (e.g., PRI: a, c); and third DCI 630 includes a third K1
value 632 (e.g., K1=1) and indicates a third set of PRI values 634.
In some implementations, UE 155 receives each of DCIs 610, 620,
630. During fourth slot position 433, UE 115 transmits PUCCH
resource 640 and PUCCH resource 650, as described herein. In some
implementations, one or more of the DCIs 610, 620, 630 indicate
more than two PRI values.
[0135] During the fourth mode, UE 115 receives the DCIs 610, 620,
630 and identifies a set of DCIs in which each DCI has the same
HARQ feedback timing indicator field (e.g., K1 value) indicating
the same slot position for PUCCH transmission of HARQ-ACK feedback.
As shown in FIG. 6, each of the DCIs 610, 620, 630 indicates fourth
slot position 433 for PUCCH transmission of HARQ-ACK feedback.
[0136] In a first implementation of the fourth mode, UE 115
identifies a last detected DCI (e.g., 630) of the set of DCIs 610,
620, 630. UE 115 determines whether to perform PUCCH repetition if
the corresponding PRI field codepoint (e.g., 634) of the last
detected DCI (e.g., 630) indicates multiple PRI values. As shown,
third DCI 630 indicates PRI value 634 as PRI: d--a single PRI.
Since PRI value 634 indicates a single PRI value, UE 315 would use
PUCCH resource 640 (e.g., PUCCH resource d corresponding to PRI
value d) to send HARQ-ACK feedback during fourth slot position 433.
In such an implementation, UE 115 would not use PUCCH resource 650
(e.g., PUCCH resource c). Alternatively, if third DCI 630 indicated
PRI values d and c, UE 115 would perform repetition during fourth
slot position 433 and would use each of PUCCH resource 640 (e.g.,
PUCCH resource d corresponding to PRI value d) and PUCCH resource
650 (e.g., PUCCH resource c corresponding to PRI value c) to send
HARQ-ACK feedback during fourth slot position 433.
[0137] In a second implementation of the fourth mode, UE 115
identifies a last detected DCI (e.g., 630) of the set of DCIs 610,
620, 630. UE 115 determines whether to perform PUCCH repetition if
at least one DCI of the set of DCI 610, 620, 630 has a
corresponding PRI field codepoint that indicates multiple PRI
values. As shown, both first DCI 610 and second DCI indicate
multiple PRI values, so UE 115 determines to perform repetition. If
the last detected DCI (e.g., 630) indicated multiple PRI values, UE
115 would use the PRI values indicated by third DCI 630.
Alternatively, if the last detected DCI (e.g., 630) indicates a
single PRI value as shown, UE 115 perform repetition using a first
PUCCH resource 640 corresponding to the single PRI value (e.g.,
PUCCH resource d) and using a second PUCCH resource 650 (e.g.,
resource c) corresponding to a most recently received DCI (e.g.,
620) of the at least one received DCI (e.g., 610, 620) that
includes the value of the PRI field codepoint corresponding to the
multiple PRI values. It is noted that if second DCI 620 indicated a
single PRI value, the most recently received DCI of the at least
one received DCI (e.g., 610) that includes the value of the PRI
field codepoint corresponding to the multiple PRI values is the
first DCI 610 and, therefore, the UE 115 would use PUCCH resource b
as the second PUCCH resource 650.
[0138] In some implementations, the fourth mode may be used based
on a determination that a TCI filed in at least one DCI 610, 620,
630 points to two TCI states (PDSCH multi-TRP schemes SDM/FDM/TDM).
In a particular implementation, the fourth mode may be used based
on a determination that a TCI in each of the DCIs 610, 620, 630
(having the same HARQ feedback timing indicator field (e.g., K1
value) indicating the same slot position for PUCCH transmission of
HARQ-ACK feedback) points to two TCI states. If at least one DCI
does not have a TCI field that points to two TCI states, or
alternatively, less than all of the DCIs a TCI that points to two
TCI states, UE 115 may operate according to Rel. 15 behavior for
the PRI value. Additionally, or alternatively, it is noted, that
the fourth mode may be used with the third mode and a mapping data
structure, such as data structure 500. Accordingly, the fourth mode
may operate based on interpreted PRI values indicated by DCIs 610,
620 630.
[0139] In a third implementation of the fourth mode, UE 115
identifies a PRI value, such as an interpreted PRI value. UE
selects a first interpreted PRI value as the PRI codepoint value
and determines the first PUCCH resource (e.g., 640) for repetition
based on the first interpreted PRI value. The UE determines whether
to use an additional (e.g., second) PUCCH resource based on one or
more rules--e.g., one or more conditions. For example, UE may
select the second PUCCH resource from among all the other PUCCH
resources within a PUCCH resource set that: do not overlap with the
first PUCCH resource; start after the first PUCCH resource; has a
different MAC-CE activated PUCCH-SpatialRelationInfo than the first
PUCCH resource; the corresponding PUCCH-SpatialRelationInfo has the
same quasi co-located (QCL) source as the second TCI state; or a
combination thereof. It is noted that the condition of the
corresponding PUCCH-SpatialRelationInfo has the same QCL source as
the second TCI state may only be applicable in the case that the
TCI field in the DCI points to two TCI states. The fourth mode of
operation or any of the implementations of the fourth mode
described herein, can be RRC configuration.
[0140] Referring to FIG. 7, an example of the third implementation
of the fourth mode is shown and designated 700. As shown, a DCI 710
(e.g., 361) includes two TCI states-- TCI state i and TCI state
j--and corresponds to PDSCH 720 and PDSCH 730. A PRI value
codepoint (a) of DCI 710 is interpreted as PRI values a and b. UE
115 selects first interpreted PRI value for the first PUCCH
resource 740 For the second PUCCH resource 750, UE 115 determines
that the TCI state j and PUCCH SpatialRelationInfo for PUCCH
resource b have the same QCL source. Based on those conditions, UE
115 selects the second PUCCH resource 750 based on PRI value b.
[0141] Thus, FIG. 3 describes PUCCH repetition. For example, a
configuration may transmit multiple repetitions (e.g., 362, 363)
using different resource or different beams. The multiple
repetitions (e.g., 362, 363) may be transmitted during the same
slot position or during different slot positions. Additionally, UE
115 may be configured to perform PUCCH repetition based on one or
more modes. Each of the one or more modes provides greater
flexibility for UE 115 to perform PUCCH repetition not realized by
conventional systems. Accordingly, PUCCH repetitions are move
likely to be received during dynamically changing network
conditions as compared to conventional systems.
[0142] FIGS. 8-12 are block diagrams illustrating example blocks
executed by a UE configured according to an aspect of the present
disclosure. The example blocks will also be described with respect
to UE 115 as illustrated in FIG. 8. FIG. 20 is a block diagram
illustrating UE 115 configured according to one aspect of the
present disclosure. UE 115 includes the structure, hardware, and
components as illustrated for UE 115 of FIG. 2 or 3. For example,
UE 115 includes controller/processor 280, which operates to execute
logic or computer instructions stored in memory 282, as well as
controlling the components of UE 115 that provide the features and
functionality of UE 115. UE 115, under control of
controller/processor 280, transmits and receives signals via
wireless radios 2001a-r and antennas 252a-r. Wireless radios
2001a-r includes various components and hardware, as illustrated in
FIG. 2 for UE 115, including modulator/demodulators 254a-r, MIMO
detector 256, receive processor 258, transmit processor 264, and TX
MIMO processor 266. As shown, memory 282 may include repetition
setting(s) 2002, mapping information 2003, setting identifier logic
2004, resource selector logic 2005, and beam generator logic 2006.
Repetition setting(s) 2002 and mapping information 2003 may include
or correspond to repetition setting(s) 340 and mapping information
326, respectively. Setting identifier logic 2004 may include or
correspond to setting(s) identifier 337. Resource selector logic
2005 may include or correspond to resource selector 338. Beam
generator logic 2006 may include or correspond to beam generator
339. In some aspects, setting identifier logic 2004, resource
selector logic 2005, beam generator logic 2006, or a combination
thereof, may include or correspond to processor(s) 280. UE 115 may
receive signals from or transmit signal to a base station, such as
base station 105 of FIG. 3 or base station 105 as illustrated in
FIG. 21.
[0143] Referring to FIG. 8, at block 800, the UE receives an RRC
configuration including a PUCCH resource. To illustrate, the UE may
receive the RRC via wireless radios 2001a-r and antennas 252a-r.
The RRC configuration may include or correspond to first message
361.
[0144] At block 801, the UE determines a set of indices for one or
more PUCCH resources. Each index of the set of indices may
correspond to a different beam of multiple beams. The multiple
beams may include a first beam and a second beam. To illustrate,
the UE may determine the set of indices using setting identifier
logic 2004. The set of indices may include or correspond to
repetition setting(s) 340.
[0145] At block 802, the UE transmits, for the PUCCH resource: a
first PUCCH repetition of multiple PUCCH repetitions using the
first beam for a first slot position of multiple slot positions;
and a second PUCCH repetition of the multiple PUCCH repetitions
using the second beam for a second slot position of the multiple
slot positions. To illustrate, the UE may transmit the first PUCCH
repetition and the second PUCCH repetition via wireless radios
2001a-r and antennas 252a-r. The first repetition and the second
repetition may include or correspond to first repetition 362 and
second repetition 363, respectively. In some implementations, the
PUCCH resource may be selected by resource selector logic 2005.
Additionally, or alternatively, the first beam and the second beam
may be generated using beam generator logic 2006. In some
implementations, the first beam corresponds to a first index of the
set of indices, the second beam corresponds to a second index of
the set of indices, or both. In some implementations, the multiple
slot positions include multiple slots or multiple sub-slots of a
slot.
[0146] In some implementation, the PUCCH resource configuration
indicates a set of resource blocks (RBs), a set of symbols, a PUCCH
format, or a combination thereof. In some such implementations, the
PUCCH format indicates to perform PUCCH repetition based on a value
of a number of slots field, such as a "nrofSlots" field of the RRC
configuration. Additionally, or alternatively, a block may include
the UE determining, based on the RRC configuration, whether to
perform PUCCH repetition using the same beam for the multiple slot
positions or using the multiple beams for the multiple slot
positions.
[0147] In some implementations, a block may include the UE
receiving a Medium Access Control (MAC)-Control Element (CE) for
the PUCCH resource, and determining, based on the MAC-CE, an
activated beam for the PUCCH resource. To illustrate, the activated
beam may be determined using setting identifier logic 2004.
[0148] In some implementations, transmitting PUCCH repetitions
includes: using the activated beam for a first slot position (e.g.,
an initial slot position) of the multiple slot positions; and using
the multiple beams for slot positions of the multiple slot
positions occurring subsequent to the first slot position. In some
such implementations, the activated beam is included as one of the
multiple beams used for the slot positions of the multiple slot
positions occurring subsequent to the first slot position.
Alternatively, the activated beam is omitted as one of the multiple
beams used for the slot positions of the multiple slot positions
occurring subsequent to the first slot position. To illustrate, the
activated beam may be included in or omitted from the multiple
beams based on repetition setting(s) 2002.
[0149] In some implementations, a number of the multiple beams is
equal to a number of slot positions of the multiple slot
positions--e.g., there is a one-to-one correspondence between the
multiple beams and the number of slot positions. If a number of the
multiple beams is less than a number of slot positions of the
multiple slot positions, transmitting PUCCH repetitions includes:
cycling through the multiple beams for a first set of slot
positions of the multiple slot positions, the first set of slot
positions including a number of slot positions equal to the number
of the multiple beams; and using one or more beams of the multiple
beams for a second set of slot positions of the multiple slot
positions.
[0150] Referring to FIG. 9, at block 900, the UE receives a first
RRC configuration including a PUCCH resource. To illustrate, the UE
may receive the first RRC via wireless radios 2001a-r and antennas
252a-r. The first RRC configuration may include or correspond to
first message 361.
[0151] At block 901, the UE receives a second RRC configuration
including a PUCCH format. To illustrate, the UE may receive the
second RRC via wireless radios 2001a-r and antennas 252a-r. The
first RRC configuration may include or correspond to first message
361. In some implementations, the first and second RRC are included
in the same message. In other implementations, the first RRC and
the second RRC are included in different messages.
[0152] In some implementations, the first RRC configuration may
include or correspond to a PUCCH-Config (e.g.,
"spatialRelationInfoToAddModList") for all PUCCH resources.
Additionally, or alternatively, the second RRC configuration may
include or correspond to a PUCCH-FormatConfig, and optionally, also
with a number of slots (e.g., "nrofSlots") field. Accordingly, an
RRC parameter for multiple beams (e.g., for purposes of repetition)
may be defined based on the first RRC, the second RRC, or both the
first and second RRCs. In some implementations, the second RRC
includes multiple PUCCH formats and, for each PUCCH format included
in the second RRC configuration, the second RRC configuration
indicates a corresponding set of one or more beams.
[0153] At block 902, the UE determines, based on the PUCCH resource
and the PUCCH format, multiple beams. The multiple beams may
include a first beam and a second beam. In some implementations, a
number of the multiple beams is equal to a number of slot positions
of the multiple slot positions--e.g., there is a one-to-one
correspondence between the multiple beams and the number of slot
positions.
[0154] At block 903, the UE transmits, for the PUCCH resource: a
first PUCCH repetition of multiple PUCCH repetitions using the
first beam for a first slot position of multiple slot positions;
and a second PUCCH repetition of the multiple PUCCH repetitions
using the second beam for a second slot position of the multiple
slot positions. The first slot position and the second slot
position may be different slot positions. To illustrate, the UE may
transmit the first PUCCH repetition and the second PUCCH repetition
via wireless radios 2001a-r and antennas 252a-r. The first
repetition and the second repetition may include or correspond to
first repetition 362 and second repetition 363, respectively. In
some implementations, the PUCCH resource may be selected by
resource selector logic 2005. Additionally, or alternatively, the
first beam and the second beam may be generated using beam
generator logic 2006. In some implementations, the first beam
corresponds to a first index of the set of indices, the second beam
corresponds to a second index of the set of indices, or both. In
some implementations, the multiple slot positions include multiple
slots or multiple sub-slots of a slot.
[0155] In some implementations, a block may include, after
transmitting the PUCCH resource, the UE receiving a third RRC
configuration including a second PUCCH resource and a fourth RRC
configuration including a second PUCCH format; and determining
whether a set of one or more beams of the second PUCCH resource
includes a single beam. If the set of one or more beams includes a
single beam, the UE may perform PUCCH repetition using the single
beam, such as PUCCH repetition across multiple slot positions where
each PUCCH repetition is transmitted using the same beam (e.g., the
same beam pattern). In some implementations, when a number of the
multiple beams is less than a number of slot positions of the
multiple slot positions, performing PUCCH repetition includes:
cycling through the multiple beams for a first set of slot
positions of the multiple slot positions, the first set of slot
positions including a number of slot positions equal to the number
of the multiple beams; and using one or more beams of the multiple
beams for a second set of slot positions of the multiple slot
positions.
[0156] Referring to FIG. 10, at block 1000, the UE receives
Downlink Control Information (DCI) including a PRI field codepoint.
To illustrate, the UE may receive the DCI via wireless radios
2001a-r and antennas 252a-r. The DCI may include or correspond to
first message 361.
[0157] At block 1001, the UE determines, based on the PRI field
codepoint, whether to transmit a PUCCH repetition within a slot
position using a single PUCCH resource or transmit multiple PUCCH
repetitions within the slot position using multiple PUCCH resources
responsive to determining to transmit the multiple PUCCH
repetitions within the slot position using the multiple PUCCH
resources. For example, the UE may determine, based on the PRI
field codepoint, to transmit PUCCH repetition within a slot
position using a single PUCCH resource, such that repetition does
not occur within the slot position, but may occur across multiple
slot positions. As another example, the UE may determine, based on
the PRI field codepoint, to transmit PUCCH repetition within a slot
position using multiple PUCCH repetitions within the slot position
using the multiple PUCCH resources, such that repetition occurs
within the slot position, as described further herein. The slot
position may include a slot or a sub-slot of the slot. In some
implementations, the slot position is a sub-slot of a slot.
[0158] At block 1002, the UE transmits multiple PUCCH repetitions
within the slot position using the multiple PUCCH resources. In
some implementations, transmitting the multiple PUCCH repetitions
includes: transmitting, using a first PUCCH resource of the
multiple PUCCH resources, a first PUCCH repetition of the multiple
PUCCH repetitions within the slot position; and transmitting, by
the UE using a second PUCCH resource of the multiple PUCCH
resources, a second PUCCH repetition of the multiple PUCCH
repetitions within the slot position. To illustrate, the UE may
transmit a first PUCCH repetition and a second PUCCH repetition via
wireless radios 2001a-r and antennas 252a-r. The first PUCCH
repetition and the second PUCCH repetition may include or
correspond to first repetition 362 and second repetition 363,
respectively. In some implementations, the PUCCH resource may be
selected by resource selector logic 2005. Additionally, or
alternatively, the first beam and the second beam may be generated
using beam generator logic 2006.
[0159] In some implementations, the UE identifies the PRI field
codepoint based on the DCI. To illustrate, the UE may identify the
PRI field codepoint using setting identifier logic 2004.
[0160] In some implementations, a block may be included in which
the UE maps the PRI field codepoint to a set of one or more
interpreted PRI values. In some such implementations, prior to
mapping, a block may include the UE receiving an RRC configuration,
and configuring, based on the RRC configuration, the UE for mapping
the PRI field codepoint to the set of one or more interpreted PRI
values. Alternatively, prior to mapping, the UE may receive a
MAC-CE, and may activate, based on the MAC-CE, a mapping
functionality at the UE for mapping the PRI field codepoint to the
set of one or more interpreted PRI values.
[0161] In some implementations, the set of one or more interpreted
PRI values includes a single interpreted PRI value. In some
implementations, the PRI field codepoint may be mapped to a single
interpreted value. For example, the interpreted PRI value may be
mapped to the same value or a different value as a value of the PRI
field codepoint. Alternatively, the set of one or more interpreted
PRI values may include multiple interpreted PRI values. In some
such implementations, at least one of the multiple interpreted PRI
values has the same value as a value of the PRI field codepoint.
When the PRI field codepoint maps to multiple interpreted PRI
values, the multiple interpreted PRI values may include a first
interpreted PRI value corresponding to a first PUCCH resource and a
second interpreted PRI value corresponding to a second PUCCH
resource. The first PUCCH resource may correspond to a first
activated beam, and the second PUCCH resource may correspond to a
second activated beam different from the first activated beam.
[0162] In some implementations, the DCI may include a Downlink (DL)
DCI scheduling a Physical Downlink Shared Channel (PDSCH), and the
PUCCH repetition includes a Hybrid Automatic Repeat Request
(HARQ)-ACK codebook. Additionally, or alternatively, a block may be
included in which the UE receives multiple DCIs, such as multiple
DCIs that include the DCI. Each of the multiple DCIs may include
including a corresponding PRI codepoint and a corresponding Hybrid
Automatic Repeat Request (HARQ) feedback timing indicator field. In
some implementations, the corresponding vales of the HARQ feedback
timing indicator field of the multiple DCIs indicate the same slot
position for PUCCH transmission of HARQ-ACK feedback. The UE may
identify a last detected DCI of the set of DCIs and may determine
to perform PUCCH repetition if the corresponding PRI field
codepoint of the last detected DCI indicates or corresponds to
multiple PRI values. In some implementations, the UE may determine
to perform PUCCH repetition based on at least one DCI of the set of
DCI has a corresponding PRI field codepoint that indicates or
corresponds to multiple PRI values. To illustrate, the UE may
identify a last detected DCI of the set of DCIs and, when the
detected DCI corresponds to a single PRI value and when the at
least one DCI of the set of DCI has a corresponding PRI field
codepoint that indicates multiple PRI values, may use a first PUCCH
resource corresponding to the single PRI value and may use a second
PUCCH resource corresponding to a most recently received DCI of the
at least one received DCI that includes the value of the PRI field
codepoint corresponding to the multiple PRI values.
[0163] Referring to FIG. 11, at block 1100, the UE receives DCI
including a PRI field codepoint. To illustrate, the UE may receive
the DCI via wireless radios 2001a-r and antennas 252a-r. The DCI
may include or correspond to first message 361.
[0164] At block 1101, the UE maps the PRI field codepoint to a set
of one or more interpreted PRI values. For example, the UE may map
the PRI field code to the set of one or more interpreted PRI values
using mapping information 2003.
[0165] At block 1102, the UE transmits multiple PUCCH repetitions
within a slot position using multiple PUCCH resources based on the
set of one or more interpreted PRI values. In some implementations,
transmitting the multiple PUCCH repetitions includes: transmitting,
using a first PUCCH resource of the multiple PUCCH resources, a
first PUCCH repetition of the multiple PUCCH repetitions within the
slot position; and transmitting, using a second PUCCH resource of
the multiple PUCCH resources, a second PUCCH repetition of the
multiple PUCCH repetitions within the slot position. To illustrate,
the UE may transmit a first PUCCH repetition and a second PUCCH
repetition via wireless radios 2001a-r and antennas 252a-r. The
first PUCCH repetition and the second PUCCH repetition may include
or correspond to first repetition 362 and second repetition 363,
respectively. In some implementations, the PUCCH resource may be
selected by resource selector logic 2005. Additionally, or
alternatively, the first beam and the second beam may be generated
using beam generator logic 2006. The slot position may include a
slot or a sub-slot of the slot. In some implementations, the slot
position is a sub-slot of a slot.
[0166] In some implementations, the UE identifies the PRI field
codepoint based on the DCI. To illustrate, the UE may identify the
PRI field codepoint using setting identifier logic 2004.
[0167] In some implementations, a block may include the UE
determining whether the DCI points to multiple TCI states. The UE
may determine to not perform mapping based on a determination that
the DCI points to a single TCI state. Alternatively, the UE may
determine to perform mapping based on a determination that the DCI
points to the multiple TCI states. Based on a determination to
perform the PUCCH repetition using the multiple PUCCH resources,
the UE may select a first PUCCH resource as a first of the multiple
PUCCH resources, the first PUCCH resource corresponding to the
value of the PRI filed codepoint, and select a second PUCCH
resource as a second of the multiple PUCCH resources. To
illustrate, the UE may select the first and second PUCCH resources
using the resource selector logic 2005. The second PUCCH resource
is selected from a set of available PUCCH resources within a PUCCH
resource set, excluding the selected PUCCH resource. For example,
the second resource may be selected based on satisfying one or more
rules/conditions, such as not overlapping with the first PUCCH
resource, starting after the first PUCCH resource, having a
different activated beam from an activated beam of the first PUCCH
resource, having an activated beam corresponding to the same QCL
source as at least one TCI state pointed to by the DCI, or a
combination thereof.
[0168] Referring to FIG. 12, at block 1200, the UE receives an RRC
configuration. To illustrate, the UE may receive the RRC via
wireless radios 2001a-r and antennas 252a-r. The RRC configuration
may include or correspond to first message 361.
[0169] At block 1201, the UE determines, based on the RRC
configuration, whether to transmit multiple PUCCH repetitions. To
illustrate, the UE may make such a determination using setting
identifier logic 2004.
[0170] At block 1202, in response to a determination to transmit
the multiple PUCCH repetitions, the UE determines whether to
transmit a single PUCCH repetition within a slot position using a
single PUCCH resource or multiple PUCCH repetitions within the slot
position using multiple PUCCH resources. To illustrate, the UE may
make such a determination using setting identifier logic 2004. The
slot position may include a slot or a sub-slot of the slot. In some
implementations, the slot position is a sub-slot of a slot.
[0171] At block 1203, the UE transmitting, by the UE, the two or
more PUCCH repetitions within the slot position using the multiple
PUCCH resources. In some implementations, transmitting the two or
more PUCCH repetitions includes: transmitting, using a first PUCCH
resource of the multiple PUCCH resources, a first PUCCH repetition
of the two or more PUCCH repetitions within the slot position; and
transmitting, by the UE using a second PUCCH resource of the
multiple PUCCH resources, a second PUCCH repetition of the two or
more PUCCH repetitions within the slot position. To illustrate, the
UE may transmit a first PUCCH repetition and a second PUCCH
repetition via wireless radios 2001a-r and antennas 252a-r. The
first PUCCH repetition and the second PUCCH repetition may include
or correspond to first repetition 362 and second repetition 363,
respectively. In some implementations, the PUCCH resource may be
selected by resource selector logic 20054. Additionally, or
alternatively, the first beam and the second beam may be generated
using beam generator logic 2006.

EEPROM, CD-ROM or other optical disk storage, magnetic disk storage
or other magnetic storage devices, or any other medium that can be
used to carry or store desired program code means in the form of
instructions or data structures and that can be accessed by a
general-purpose or special-purpose computer, or a general-purpose
or special-purpose processor. Also, a connection may be properly
termed a computer-readable medium. For example, if the software is
transmitted from a website, server, or other remote source using a
coaxial cable, fiber optic cable, twisted pair, or digital
subscriber line (DSL), then the coaxial cable, fiber optic cable,
twisted pair, or DSL, are included in the definition of medium.
Disk and disc, as used herein, includes compact disc (CD), laser
disc, optical disc, digital versatile disc (DVD), floppy disk and
blu-ray disc where disks usually reproduce data magnetically, while
discs reproduce data optically with lasers. Combinations of the
above should also be included within the scope of computer-readable
media.
[0307] As used herein, including in the claims, the term "and/or,"
when used in a list of two or more items, means that any one of the
listed items can be employed by itself, or any combination of two
or more of the listed items can be employed. For example, if a
composition is described as containing components A, B, and/or C,
the composition can contain A alone; B alone; C alone; A and B in
combination; A and C in combination; B and C in combination; or A,
B, and C in combination. Also, as used herein, including in the
claims, "or" as used in a list of items prefaced by "at least one
of" indicates a disjunctive list such that, for example, a list of
"at least one of A, B, or C" means A or B or C or AB or AC or BC or
ABC (i.e., A and B and C) or any of these in any combination
thereof.
[0308] The previous description of the disclosure is provided to
enable any person skilled in the art to make or use the disclosure.
Various modifications to the disclosure will be readily apparent to
those skilled in the art, and the generic principles defined herein
may be applied to other variations without departing from the
