ON-DEMAND BACKHAUL LINK MANAGEMENT MEASUREMENTS FOR INTEGRATED
ACCESS BACKHAUL FOR 5G OR OTHER NEXT GENERATION NETWORK
Abstract
The same or similar physical signals can be used for both user
equipment (UE) and an integrate access backhaul (IAB) node.
Different configurations of the resources and/or transmission
periods of the signals can be used for initial access for access
UEs and IAB nodes. In addition, to support topology formation,
mobility/multi-connectivity procedures, and backhaul link
management, periodic measurements and reports can be configured by
a parent IAB node to a child IAB node UE function. This can
comprise radio resource management (RRM), radio link monitoring
(RLM), and beam management (L1-BM) measurements and reports.

backhaul link management and measurements. For example, this
disclosure relates to facilitating on-demand backhaul link
management measurements for integrated access backhaul for a 5G, or
other next generation network.
BACKGROUND
[0003] 5th generation (5G) wireless systems represent a next major
phase of mobile telecommunications standards beyond the current
telecommunications standards of 4.sup.th generation (4G). Rather
than faster peak Internet connection speeds, 5G planning aims at
higher capacity than current 4G, allowing a higher number of mobile
broadband users per area unit, and allowing consumption of higher
or unlimited data quantities. This would enable a large portion of
the population to stream high-definition media many hours per day
with their mobile devices, when out of reach of wireless fidelity
hotspots. 5G research and development also aims at improved support
of machine-to-machine communication, also known as the Internet of
things, aiming at lower cost, lower battery consumption, and lower
latency than 4G equipment.

phrase "in one embodiment," "in one aspect," or "in an embodiment,"
in various places throughout this specification are not necessarily
all referring to the same embodiment. Furthermore, the particular
features, structures, or characteristics may be combined in any
suitable manner in one or more embodiments.
[0022] As utilized herein, terms "component," "system,"
"interface," and the like are intended to refer to a

[0023] Further, these components can execute from various
machine-readable media having various data structures stored
thereon. The components can communicate via local and/or remote
processes such as in accordance with a signal having one or more
data packets (e.g., data from one component interacting with
another component in a local system, distributed system, and/or
across a network, e.g., the Internet, a local area network, a wide
area network, etc. with other systems via the signal).
[0024] As another example, a component can be an apparatus with
specific functionality provided by mechanical parts operated by
electric or electronic circuitry; the electric or electronic
circuitry can be operated by a software application or a firmware
application executed by one or more processors; the one or more

[0027] Inference can also refer to techniques employed for
composing higher-level events from a set of events and/or data.
Such inference results in the construction of new events or actions
from a set of observed events and/or stored event data, whether the
events are correlated in close temporal proximity, and whether the
events and data come from one or several event and data sources.
Various classification schemes and/or systems (e.g., support vector

(e.g., a machine-readable storage medium) to facilitate
transporting and transferring such methodologies to computers. The
term article of manufacture, as used herein, is intended to
encompass a computer program accessible from any computer-readable
device, carrier, or media, including a non-transitory
machine-readable storage medium.
[0030] It should be noted that although various aspects and
embodiments have been described herein in the context of 5G,
Universal Mobile Telecommunications System (UMTS), and/or Long Term
Evolution (LTE), or other next generation networks, the disclosed
aspects are not limited to 5G, a UMTS implementation, and/or an LTE
implementation as the techniques can also be applied in 3G, 4G or
LTE systems. For example, aspects or features of the disclosed
embodiments can be exploited in substantially any wireless
communication technology. Such wireless communication technologies

Downlink Packet Access (HSDPA), High-Speed Uplink Packet Access
(HSUPA), Zigbee, or another IEEE 802.XX technology. Additionally,
substantially all aspects disclosed herein can be exploited in
legacy telecommunication technologies.
[0031] Described herein are systems, methods, articles of
manufacture, and other embodiments or implementations that can
facilitate on-demand backhaul link management and measurements for
a 5G network. Facilitating on-demand backhaul link management and
measurements for a 5G network can be implemented in connection with
any type of device with a connection to the communications network
(e.g., a mobile handset, a computer, a handheld device, etc.) any
Internet of things (JOT) device (e.g., toaster, coffee maker,
blinds, music players, speakers, etc.), and/or any connected
vehicles (cars, airplanes, space rockets, and/or other at least
partially automated vehicles (e.g., drones)). In some embodiments
the non-limiting term user equipment (UE) is used. It can refer to
any type of wireless device that communicates with a radio network
node in a cellular or mobile communication system. Examples of UE
are target device, device to device (D2D) UE, machine type UE or UE
capable of machine to machine (M2M) communication, PDA, Tablet,
mobile terminals, smart phone, laptop embedded equipped (LEE),
laptop mounted equipment (LME), USB dongles etc. Note that the
terms element, elements and antenna ports can be interchangeably
used but carry the same meaning in this disclosure. The embodiments
are applicable to single carrier as well as to multicarrier (MC) or
carrier aggregation (CA) operation of the UE. The term carrier
aggregation (CA) is also called (e.g., interchangeably called)
"multi-carrier system", "multi-cell operation", "multi-carrier
operation", "multi-carrier" transmission and/or reception.
[0032] In some embodiments the non-limiting term radio network node
or simply network node is used. It can refer to any type of network
node that serves UE is connected to other network nodes or network
elements or any radio node from where UE receives a signal.
Examples of radio network nodes are Node B, base station (BS),
multi-standard radio (MSR) node such as MSR BS, eNode B, network
controller, radio network controller (RNC), base station controller
(BSC), relay, donor node controlling relay, base transceiver
station (BTS), access point (AP), transmission points, transmission
nodes, RRU, RRH, nodes in distributed antenna system (DAS) etc.
[0033] Cloud radio access networks (RAN) can enable the
implementation of concepts such as software-defined network (SDN)
and network function virtualization (NFV) in 5G networks. This
disclosure can facilitate a generic channel state information
framework design for a 5G network. Certain embodiments of this
disclosure can comprise an SDN controller that can control routing
of traffic within the network and between the network and traffic
destinations. The SDN controller can be merged with the 5G network
architecture to enable service deliveries via open application
programming interfaces ("APIs") and move the network core towards
an all internet protocol ("IP"), cloud based, and software driven
telecommunications network. The SDN controller can work with, or
take the place of policy and charging rules function ("PCRF")
network elements so that policies such as quality of service and
traffic management and routing can be synchronized and managed end
to end.
[0034] To meet the huge demand for data centric applications, 4G
standards can be applied 5G, also called new radio (NR) access. 5G
networks can comprise the following: data rates of several tens of
megabits per second supported for tens of thousands of users; 1
gigabit per second can be offered simultaneously to tens of workers
on the same office floor; several hundreds of thousands of
simultaneous connections can be supported for massive sensor
deployments; spectral efficiency can be enhanced compared to 4G;
improved coverage; enhanced signaling efficiency; and reduced
latency compared to LTE. In multicarrier system such as OFDM, each
subcarrier can occupy bandwidth (e.g., subcarrier spacing). If the
carriers use the same bandwidth spacing, then it can be considered
a single numerology. However, if the carriers occupy different
bandwidth and/or spacing, then it can be considered a multiple
numerology.
[0035] Due to the expected larger bandwidth available for NR
compared to LTE (e.g., mmWave spectrum) along with the native
deployment of MIMO or multi-beam systems in NR, there is now an
opportunity to develop and deploy integrated access and backhaul
links. This can allow for deployment of a dense network of
self-backhauled NR cells in an integrated manner by building upon
control and data channels/procedures defined for providing access
to UEs. An example illustration of a network with such integrated
access and backhaul links can comprise a relay node (Relay DU) that
can multiplex access and backhaul links in time, frequency, or
space (e.g., beam-based operation).
[0036] While an integrated access backhaul (IAB) can be deployed in
a standalone architecture where the access UEs and relay DUs
receive both control and data bearers on NR, it is also possible to
support IAB operation under a non-standalone (NSA) architecture
where the control plane signalling is sent over LTE or another NR
anchor carrier (e.g., sub6-GHz).
[0037] In an exemplary protocol stack structure for an IAB node, if
the backhaul links carrying relay traffic (Ur) are based on the
same channels and protocols as the access links carrying user data
traffic (Uu), then it is possible to construct the IAB node as
containing two parallel protocol stacks, one containing a UE
function or also called a mobile termination (MT) function, which
provides connectivity between the IAB node and a lower order IAB
node or donor node which has a wired connection to the core
network. The other IAB node functionality can be the gNB function
or distributed unit (DU) function, which can provide connectivity
between the IAB node and a higher order IAB node or access UEs.
[0038] In order to route the relay data traffic within the IAB
node, in one example, an adaptation layer can be inserted above a
radio link control (RLC) of both the UE and gNB functions of the
IAB node. In other examples an adaptation layer can be inserted
above the medium access control (MAC) and Packet Data Control
Protocol (PDCP) layers. In addition to data routing, the IAB node
can manage the control plane signalling and configurations for both
the UE and gNB functions. An example of control plan signalling for
the UE function can involve a radio resource control (RRC) and an
F1 interface and operations, administration and maintenance (OAM)
for the gNB function. This coordination can be performed internally
in the IAB node by an IAB control (IAB-C) interface.
[0039] The control plane configuration of the UE and gNB function
can be performed at the parent IAB node if it is a donor gNB, or it
can be forwarded from the parent IAB node across one or more
backhaul link hops from a central configuration entity or entities
(e.g., at the gNB central-unit (CU) or RAN/OAM controller).
[0040] The IAB nodes can multiplex the access and backhaul links in
time, frequency, or space (e.g., beam-based operation), which
includes the transmission of signals/channels utilized as part of
initial access and measurements used for radio resource management.
The same physical layer signals and channels used for these
purposes by access UEs can be reused use for performing similar
procedures at the IAB node.
[0041] However, since the IAB nodes have both gNB functionality as
well as UE functionality, the IAB node gNB function (e.g., IAB-DU)
can transmit signals and channels used for backhaul link monitoring
as well as receive reports from connected devices which can be both
access UEs and higher order IAB nodes. At the same time, due to the
hierarchical topology used for IAB, the UE function (e.g., IAB-MT)
of the IAB node can perform backhaul measurements and send
measurement reports for various procedures such as radio resource
management (RRM), radio link monitoring (RLM), and L1 beam
management to higher order parent nodes (e.g., IAB nodes or donor
nodes).
[0042] In order to support topology formation,
mobility/multi-connectivity procedures, and backhaul link
management, periodic measurements and reports can be configured by
a parent IAB node to a child IAB node UE function (e.g., IAB-MT).
This can include radio resource management (RRM), radio link
monitoring (RLM), and L1 beam management (L1-BM) measurements and
reports.
[0043] Once the IAB-MT is connected to the network (e.g. in RRC
CONNECTED mode), the network can provide a synchronization signal
block (SSB) measurement and timing configuration (SMTC) for the IAB
node UE, which can comprise the timing of SSB transmissions
(including periodicity) and a list of SSB indices (e.g. bitmap)
that the UE should utilize for performing RRM measurements,
performing RLM in-sync/out-of-sync determinations, and selecting
the best serving transmission beam based on L1-BM measurements. SSB
measurements can additionally be used for topology/route management
or mobility in case of mobile relay node operations.
[0044] As discussed previously, frequent transmission of SSBs can
result in excessive overhead and result in undesirable scheduling
restrictions on the IAB node gNB function since data transmissions
cannot be scheduled when the IAB node UE function is performing
measurements. Instead of relying on SSB-based measurements, the
network can utilize CSI-RS for RRM/RLM/L1-BM functions and topology
and route management measurements since the CSI-RS can have lower
time/frequency resource overhead and can specifically be
UE-configured with finer granularity than SSB-based
measurements.
[0045] In mmWave frequencies, multiple SSBs can be transmitted in
different spatial directions using different beams formed by the
gNB antenna panel. While SSBs are transmitted in a cell-specific
manner, CSI-RS can also be transmitted in different spatial
directions with the same beamwidth or narrower beamwidth than SSBs
depending on the analog/digital beamforming weights. Unlike SSBs,
CSI-RS can be UE configured with a subset of CSI-RS resources
dedicated for given UE or group of UEs depending on their spatial
location.
[0046] The network can configure CSI-RS configurations 1-1, 1-2,
and 1-3 to be associated with SSB 1 and CSI-RS configurations 2-1,
2-2, and 2-3 to be associated with SSB 2. The configuration of a
CSI-RS can therefore be based on feedback from the UE on the
strongest SSB. For IAB, the parent node can utilize SSB based
measurements for regular access UEs to avoid the need for
determining an appropriate CSI-RS configuration (which can change
due to link blockage or UE mobility events), however for IAB nodes
which can be largely stationary, after initial access the network
can configure a CSI-RS measurement configuration where the CSI-RS
configuration is based on the associated SSB timing pattern (e.g.,
alternating or staggered). In case the CSI-RS is used for inter-IAB
node measurements, the same or different muting patterns can be
configured and utilized by IAB nodes, since the CSI-RS can have
different granularity in terms of time/frequency resources and
number of supported beams compared to SSB based muting
configurations.
[0047] Since the IAB nodes cannot need to perform frequent SSB
detection/measurements compared to access UEs due to lack of
mobility or slow varying topology (e.g., IAB nodes turning on/off),
the resource configuration and periodicity for the SSBs used by
access UEs, which are not muted, can be different from the resource
configuration and periodicity used for SSB transmissions of the IAB
nodes, which are subject to the muting pattern. Furthermore, the
network can wish to trigger on-demand inter-IAB node discovery and
measurement. In this case, the network can configure a large
periodicity for the periodic IAB discovery measurements and
depending on the network determination (e.g., new IAB node power-on
or traffic load balancing event), send signalling to the IAB nodes
to perform IAB node discovery at specific time instances/durations
and apply a specific IAB muting pattern. This can be beneficial
since the network can only indicate to a subset of IAB nodes to
perform the inter-IAB node discovery, which can minimize the
overhead of the SSB transmissions or the required orthogonality
(e.g., number of uniquely discoverable nodes) of the muting
pattern. In addition, the IAB node can send signalling to the
network requesting aperiodic inter-IAB node discovery to be
triggered for a certain duration and with a specific time/frequency
resource configuration.
[0048] In addition to on-demand triggering of inter-IAB node
discovery and RRM measurement, the reporting to the network of the
measurements from IAB nodes can also be aperiodic and based on
event criteria. For example, if an IAB node performs a measurement
during a given discovery period and does not detect any additional
IAB nodes, it cannot provide an updated measurement/detection
report to the network in order to avoid the overhead of such UL
transmissions. In another example, the IAB node provides a
measurement report if newly discovered IAB nodes are detected, or
if the measurement quantity (e.g., reference signal received power
(RSRP/reference signal received quality (RSRQ)) has changed outside
of a configured range compared to a previous measurement or
increases/decreases compared to an absolute threshold configured by
the network.
[0049] For the purpose of backhaul link RLM, either SSB or CSI-RS
based in-sync (IS)/out-of-sync (OOS) determinations can be made.
However, similar to the inter-IAB node discovery case, frequent
transmissions of the reference signals by the parent or donor node
can increase the overhead and impact of the scheduling restrictions
imposed by the half-duplex constraint at the child IAB node. As a
result, the IAB-MT can be configured with both periodic and
aperiodic RLM, where the periodic configuration can use a large
periodicity and the aperiodic configuration can be activated by the
network based on one or more criteria such as CSI feedback, L1-BM
RSRP, RRM measurement reports, or indication of beam failure or
partial beam failure.
[0050] In another alternative embodiment, the IAB-MT can make a
request for aperiodic RLM to be configured using signalling, which
can indicate the timing and resource configuration (including
reference signal type). The aperiodic RLM request can be triggered
at the IAB-MT based on criteria such as link quality metrics
derived from periodic IS/OOS reports falling below a given
threshold or based on other measurements such as CSI/L1-RSRP/RRM
measurements. In another alternative the IAB-MT can make the
aperiodic RLM request based on a request from the IAB-DU to support
a desired IAB node transmission/reception state across the IAB
node, subject to the half-duplex constraint.
[0051] L1-BM measurements and reports based on SSBs or CSI-RS can
be used for backhaul link beam management and also potentially
cross-link interference (CLI) measurements across backhaul links,
aperiodic measurements and reports can be configured. For access
links which are subject to frequent mobility or blockage events,
the IAB-MT cannot need to report non-CQI aspects of the L1-BM
reports (e.g., L1-RSRP, N best Tx beams, or SINR metric) unless
there has been a change in those metrics above a network configured
threshold or other backhaul link quality criteria. This is
beneficial to save reporting overhead, and support event-driven
operation of the backhaul beam management/CLI reports similar to
that previously described for RRM reports.
[0052] In one embodiment, described herein is a method comprising
connecting, by a first wireless network device comprising a
processor, a mobile device function of the first wireless network
device to a second wireless network device. In response to the
connecting, the method can comprise receiving, by the first

first wireless network device.
[0053] According to another embodiment, a system can facilitate
connecting a mobile device function, of a first wireless network
device, to a second wireless network device. In response to the
connecting, the system can comprise receiving for the mobile device
function, synchronization signal block data representative of a
synchronization signal block measurement associated with a

synchronization signal block data, the system can comprise
performing a radio resource measurement, wherein the radio resource
measurement comprises a beam management measurement. Additionally,
based on the beam management measurement, the system can comprise
selecting a transmission beam to be used by the first wireless
network device.
[0054] In yet another embodiment, described herein is a
machine-readable medium that can perform the operations comprising
facilitating connecting a mobile device function, of a first
wireless network device, to a second wireless network device. The
machine-readable medium can perform the operations comprising
facilitating receiving, for the mobile device function,

Furthermore, based on the beam management measurement, the
machine-readable medium can perform the operations comprising
facilitating selecting a transmission beam to be used by the first
wireless network device.
[0055] These and other embodiments or implementations are described
in more detail below with reference to the drawings.
[0056] Referring now to FIG. 1, illustrated is an example wireless
communication system 100 in accordance with various aspects and
embodiments of the subject disclosure. In one or more embodiments,
system 100 can comprise one or more user equipment UEs 102. The
non-limiting term user equipment can refer to any type of device
that can communicate with a network node in a cellular or mobile
communication system. A UE can have one or more antenna panels
having vertical and horizontal elements. Examples of a UE comprise
a target device, device to device (D2D) UE, machine type UE or UE
capable of machine to machine (M2M) communications, personal
digital assistant (PDA), tablet, mobile terminals, smart phone,
laptop mounted equipment (LME), universal serial bus (USB) dongles
enabled for mobile communications, a computer having mobile
capabilities, a mobile device such as cellular phone, a laptop
having laptop embedded equipment (LEE, such as a mobile broadband
adapter), a tablet computer having a mobile broadband adapter, a
wearable device, a virtual reality (VR) device, a heads-up display
(HUD) device, a smart car, a machine-type communication (MTC)
device, and the like. User equipment UE 102 can also comprise IOT
devices that communicate wirelessly.
[0057] In various embodiments, system 100 is or comprises a
wireless communication network serviced by one or more wireless
communication network providers. In example embodiments, a UE 102
can be communicatively coupled to the wireless communication
network via a network node 104. The network node (e.g., network
node device) can communicate with user equipment (UE), thus
providing connectivity between the UE and the wider cellular
network. The UE 102 can send transmission type recommendation data
to the network node 104. The transmission type recommendation data
can comprise a recommendation to transmit data via a closed loop
MIMO mode and/or a rank-1 precoder mode.
[0058] A network node can have a cabinet and other protected
enclosures, an antenna mast, and multiple antennas for performing
various transmission operations (e.g., MIMO operations). Network
nodes can serve several cells, also called sectors, depending on
the configuration and type of antenna. In example embodiments, the
UE 102 can send and/or receive communication data via a wireless
link to the network node 104. The dashed arrow lines from the
network node 104 to the UE 102 represent downlink (DL)
communications and the solid arrow lines from the UE 102 to the
network nodes 104 represents an uplink (UL) communication.
[0059] System 100 can further include one or more communication
service provider networks 106 that facilitate providing wireless
communication services to various UEs, including UE 102, via the
network node 104 and/or various additional network devices (not
shown) included in the one or more communication service provider
networks 106. The one or more communication service provider
networks 106 can include various types of disparate networks,
including but not limited to: cellular networks, femto networks,
picocell networks, microcell networks, internet protocol (IP)
networks Wi-Fi service networks, broadband service network,
enterprise networks, cloud based networks, and the like. For
example, in at least one implementation, system 100 can be or
include a large scale wireless communication network that spans
various geographic areas. According to this implementation, the one
or more communication service provider networks 106 can be or
include the wireless communication network and/or various
additional devices and components of the wireless communication
network (e.g., additional network devices and cell, additional UEs,
network server devices, etc.). The network node 104 can be
connected to the one or more communication service provider
networks 106 via one or more backhaul links 108. For example, the
one or more backhaul links 108 can comprise wired link components,
such as a T1/E1 phone line, a digital subscriber line (DSL) (e.g.,
either synchronous or asynchronous), an asymmetric DSL (ADSL), an
optical fiber backbone, a coaxial cable, and the like. The one or
more backhaul links 108 can also include wireless link components,
such as but not limited to, line-of-sight (LOS) or non-LOS links
which can include terrestrial air-interfaces or deep space links
(e.g., satellite communication links for navigation).
[0060] Wireless communication system 100 can employ various
cellular systems, technologies, and modulation modes to facilitate
wireless radio communications between devices (e.g., the UE 102 and
the network node 104). While example embodiments might be described
for 5G new radio (NR) systems, the embodiments can be applicable to
any radio access technology (RAT) or multi-RAT system where the UE
operates using multiple carriers e.g., LTE FDD/TDD, GSM/GERAN,
CDMA2000 etc.
[0061] For example, system 100 can operate in accordance with
global system for mobile communications (GSM), universal mobile
telecommunications service (UMTS), long term evolution (LTE), LTE
frequency division duplexing (LTE FDD, LTE time division duplexing
(TDD), high speed packet access (HSPA), code division multiple
access (CDMA), wideband CDMA (WCMDA), CDMA2000, time division
multiple access (TDMA), frequency division multiple access (FDMA),
multi-carrier code division multiple access (MC-CDMA),
single-carrier code division multiple access (SC-CDMA),
single-carrier FDMA (SC-FDMA), orthogonal frequency division
multiplexing (OFDM), discrete Fourier transform spread OFDM
(DFT-spread OFDM) single carrier FDMA (SC-FDMA), Filter bank based
multi-carrier (FBMC), zero tail DFT-spread-OFDM (ZT DFT-s-OFDM),
generalized frequency division multiplexing (GFDM), fixed mobile
convergence (FMC), universal fixed mobile convergence (UFMC),
unique word OFDM (UW-OFDM), unique word DFT-spread OFDM (UW
DFT-Spread-OFDM), cyclic prefix OFDM CP-OFDM,
resource-block-filtered OFDM, Wi Fi, WLAN, WiMax, and the like.
However, various features and functionalities of system 100 are
particularly described wherein the devices (e.g., the UEs 102 and
the network device 104) of system 100 are configured to communicate
wireless signals using one or more multi carrier modulation
schemes, wherein data symbols can be transmitted simultaneously
over multiple frequency subcarriers (e.g., OFDM, CP-OFDM,
DFT-spread OFMD, UFMC, FMBC, etc.). The embodiments are applicable
to single carrier as well as to multicarrier (MC) or carrier
aggregation (CA) operation of the UE. The term carrier aggregation
(CA) is also called (e.g., interchangeably called) "multi-carrier
system", "multi-cell operation", "multi-carrier operation",
"multi-carrier" transmission and/or reception. Note that some
embodiments are also applicable for Multi RAB (radio bearers) on
some carriers (that is data plus speech is simultaneously
scheduled).
[0062] In various embodiments, system 100 can be configured to
provide and employ 5G wireless networking features and
functionalities. 5G wireless communication networks are expected to
fulfill the demand of exponentially increasing data traffic and to
allow people and machines to enjoy gigabit data rates with
virtually zero latency. Compared to 4G, 5G supports more diverse
traffic scenarios. For example, in addition to the various types of
data communication between conventional UEs (e.g., phones,
smartphones, tablets, PCs, televisions, Internet enabled
televisions, etc.) supported by 4G networks, 5G networks can be
employed to support data communication between smart cars in
association with driverless car environments, as well as machine
type communications (MTCs). Considering the drastic different
communication needs of these different traffic scenarios, the
ability to dynamically configure waveform parameters based on
traffic scenarios while retaining the benefits of multi carrier
modulation schemes (e.g., OFDM and related schemes) can provide a
significant contribution to the high speed/capacity and low latency
demands of 5G networks. With waveforms that split the bandwidth
into several sub-bands, different types of services can be
accommodated in different sub-bands with the most suitable waveform
and numerology, leading to an improved spectrum utilization for 5G
networks.
[0063] To meet the demand for data centric applications, features
of proposed 5G networks may comprise: increased peak bit rate
(e.g., 20 Gbps), larger data volume per unit area (e.g., high
system spectral efficiency--for example about 3.5 times that of
spectral efficiency of long term evolution (LTE) systems), high
capacity that allows more device connectivity both concurrently and
instantaneously, lower battery/power consumption (which reduces
energy and consumption costs), better connectivity regardless of
the geographic region in which a user is located, a larger numbers
of devices, lower infrastructural development costs, and higher
reliability of the communications. Thus, 5G networks may allow for:
data rates of several tens of megabits per second should be
supported for tens of thousands of users, 1 gigabit per second to
be offered simultaneously to tens of workers on the same office
floor, for example; several hundreds of thousands of simultaneous
connections to be supported for massive sensor deployments;
improved coverage, enhanced signaling efficiency; reduced latency
compared to LTE.
[0064] The upcoming 5G access network may utilize higher
frequencies (e.g., >6 GHz) to aid in increasing capacity.
Currently, much of the millimeter wave (mmWave) spectrum, the band
of spectrum between 30 gigahertz (GHz) and 300 GHz is
underutilized. The millimeter waves have shorter wavelengths that
range from 10 millimeters to 1 millimeter, and these mmWave signals
experience severe path loss, penetration loss, and fading. However,
the shorter wavelength at mmWave frequencies also allows more
antennas to be packed in the same physical dimension, which allows
for large-scale spatial multiplexing and highly directional
beamforming.
[0065] Performance can be improved if both the transmitter and the
receiver are equipped with multiple antennas. Multi-antenna
techniques can significantly increase the data rates and
reliability of a wireless communication system. The use of multiple
input multiple output (MIMO) techniques, which was introduced in
the third-generation partnership project (3GPP) and has been in use
(including with LTE), is a multi-antenna technique that can improve
the spectral efficiency of transmissions, thereby significantly
boosting the overall data carrying capacity of wireless systems.
The use of multiple-input multiple-output (MIMO) techniques can
improve mmWave communications, and has been widely recognized a
potentially important component for access networks operating in
higher frequencies. MIMO can be used for achieving diversity gain,
spatial multiplexing gain and beamforming gain. For these reasons,
MIMO systems are an important part of the 3rd and 4th generation
wireless systems, and are planned for use in 5G systems.
[0066] Referring now to FIG. 2, illustrated is an example schematic
system block diagram of a message sequence chart between a network
node and user equipment according to one or more embodiments.
[0067] FIG. 2 depicts a message sequence chart for downlink data
transfer in 5G systems 200. The network node 104 can transmit
reference signals to a user equipment (UE) 102. The reference
signals can be cell specific and/or user equipment 102 specific in
relation to a profile of the user equipment 102 or some type of
mobile identifier. From the reference signals, the user equipment
102 can compute channel state information (CSI) and compute
parameters needed for a CSI report at block 202. The CSI report can
comprise: a channel quality indicator (CQI), a pre-coding matrix
index (PMI), rank information (RI), a CSI-resource indicator (e.g.,
CRI the same as beam indicator), etc.
[0068] The user equipment 102 can then transmit the CSI report to
the network node 104 via a feedback channel either on request from
the network node 104, a-periodically, and/or periodically. A
network scheduler can leverage the CSI report to determine downlink
transmission scheduling parameters at 204, which are particular to
the user equipment 102. The scheduling parameters 204 can comprise
modulation and coding schemes (MCS), power, physical resource
blocks (PRBs), etc. FIG. 2 depicts the physical layer signaling
where the density change can be reported for the physical layer
signaling or as a part of the radio resource control (RRC)
signaling. In the physical layer, the density can be adjusted by
the network node 104 and then sent over to the user equipment 102
as a part of the downlink control channel data. The network node
104 can transmit the scheduling parameters, comprising the adjusted
densities, to the user equipment 102 via the downlink control
channel. Thereafter and/or simultaneously, data can be transferred,
via a data traffic channel, from the network node 104 to the user
equipment 102.
[0069] Referring now to FIG. 3, illustrated is an example schematic
system block diagram of integrated access and backhaul links
according to one or more embodiments. For example, the network 300,
as represented in FIG. 3 with integrated access and backhaul links,
can allow a relay node to multiplex access and backhaul links in
time, frequency, and/or space (e.g., beam-based operation). Thus,
FIG. 3 illustrates a generic IAB set-up comprising a core network
302, a centralized unit 304, a donor distributed unit 306, a relay
distributed unit 308, and UEs 1021, 1022, 1023. The donor
distributed unit 306 (e.g., access point) can have a wired backhaul
with a protocol stack and can relay the user traffic for the UEs
1021, 1022, 1023 across the IAB and backhaul link. Then the relay
distributed unit 308 can take the backhaul link and convert it into
different strains for the connected UEs 1021, 1022, 1023. Although
FIG. 3 depicts a single hop (e.g., over the air), it should be
noted that multiple backhaul hops can occur in other
embodiments.
[0070] The relays can have the same type of distributed unit
structure that the gNode B has. For 5G, the protocol stack can be
split, where some of the stack is centralized. For example, the
PDCP layer and above can be at the centralized unit 304, but in a
real time application part of the protocol stack, the RLC, the MAC,
and the PHY can be co-located with the base station wherein the
system can comprise an F1 interface. In order to add relaying, the
F1 interface can be wireless so that the same structure of the
donor distributed unit 306 can be kept.
[0071] Referring now to FIG. 4, illustrated is an example schematic
system block diagram of an integrated access backhaul (IAB) node
400 protocol stack according to one or more embodiments. The IAB
node 400 can receive relay links (Ur) in the same manner that a UE
receives and processes relay links. For example, the data traffic
from the UE function 404 can transition up to the adaption layer
408 and then transition down to the gNode B function 406 of the IAB
node 400. From there the data can be sent to another user or to
another backhaul node if there are additional hops. With reference
to FIG. 3, The IAB node 400 protocol stack can be between the donor
distributed unit 306 and the relay distributed unit 308. An IAB
control interference 402 can be introduced because the UE function
404 can be configured by the network and typically uses RRC
signaling to for the configuration. However, the gNode B function
406 (relay distributed unit 308) can be controlled by the F1/OAM.
Thus, a separate protocol stack can be leveraged for the gNode B
function 406 and the IAB control interface 402 can connect the UE
function 404 to the gNode B function 406 to can coordinate radio
resources.
[0072] Referring now to FIG. 5 illustrates an example schematic
system block diagram of an in-band operation of backhaul and access
links according to one or more embodiments. In the case of in-band
operation of backhaul and access links, due to the half-duplexing
constraint, IAB nodes are expected to do the following: 1) receive
on the access link and/or backhaul link at any given time; and 2)
transmit on the access link and/or backhaul link at any given
time.
[0073] As a result, while the same physical signals can be used for
both the UE and the IAB node, different configurations of the
resources and/or transmission period(s) of the signals used for
initial access for access UEs and IAB nodes can be required. In
addition, since the UE functionality for IAB nodes is not fully
identical with access UEs (e.g., optimized physical layer
parameters, support for control plane messaging related to relay
route/topology management) the network can identify which UEs
performing initial access are normal access UEs 500 or IAB nodes
with UE functionality 502. Also, the parameters configuring radio
resource management (RRM) operations at the IAB node gNB function
can consider the half-duplex constraint imposed by the UE function
and can also take into account hop order and other topology/route
management functionalities. As a result, periodic measurements and
reports may not be optimal for IAB operation due to the overhead
and scheduling constraints imposed by the half-duplex
constraint.
[0074] Referring now to FIG. 6, illustrated is an example muting
pattern according to one or more embodiments. In one embodiment the
SSB transmissions may be muted according to a predefined or
(pseudo) random pattern. An example of an SSB muting pattern is
shown in FIG. 6 where different patterns can be used by different
IAB nodes to ensure that all IAB nodes have equal periods where
they transmit SSBs and where there are able to make SSB
measurements from the transmissions of other IAB nodes. In FIG. 6,
nodes transmitting pattern 0 or pattern 2 in the first SSB burst
window can detect and measure the transmissions of nodes
transmitting pattern 1, while nodes transmitting pattern 0 cannot
detect pattern 2 and nodes transmitting pattern 2 can detect
pattern 0 in the same window. However, in the next window, which
occurs after a configured SSB burst periodicity (e.g., 80 ms) the
pattern can be changed such that the IAB nodes transmitting pattern
0 and pattern 2 can detect each other's SSB transmissions. Thus, it
is possible for all IAB nodes to detect transmissions of all other
nodes within the total muting pattern duration.
[0075] The utilization of a given pattern by an IAB node can be
based on a network (pre) configuration, which can indicate the
time/frequency resources for SSB transmissions within a given burst
duration as well as the muting pattern periodicity. Additionally,
the muting pattern can be configured by (pseudo) random parameters
such as physical cell ID, IAB node ID (including IAB-DU and/or
IAB-MT ID), route/hop order ID, or other higher layer configured
parameter.
[0076] Referring now to FIG. 7, illustrated is an example schematic
system block diagram of integrated access backhaul link SSB pattern
options according to one or more embodiments. Although SS block
configuration can be used with the disclosed system, a CSI-RS
configuration 700 can also be used to take advantage of their
narrower beams and utilize the CSI-RS resources needed for a given
relay node or a given UE. To utilize the CSI-RS configuration 700,
the system can first connect using the SS blocks SSB1, SSB2
(depicted as 702). Then, the network can determine and leverage
CSI-RS resources CSI-RS 1-1, CSI-RS 1-2, CSI-RS 1-3, CSI-RS 2-1,
CSI-RS 2-2, CSI-RS 2-3. The network can then determine which CSI-RS
resources (e.g., CSI-RS 1-1, CSI-RS 1-2, CSI-RS 1-3) can be used
for the relay nodes using SSB1 and/or which CSI-RS resources (e.g.,
CSI-RS 2-1, CSI-RS 2-2, CSI-RS 2-3) can be used for the UEs using
SSB2 (e.g., depicted as 704). Next, the network can coordinate the
CSI-RS resources CSI-RS 1-1, CSI-RS 1-2, CSI-RS 1-3, CSI-RS 2-1,
CSI-RS 2-2, CSI-RS 2-3 by utilizing the IAB control interface.
[0077] Referring now to FIG. 8, illustrated is an example schematic
system block diagram of an example criteria-based management report
according to one or more embodiments. In addition to on-demand
triggering of inter-IAB node discovery and RRM measurement, the
reporting to the network of the measurements from IAB nodes can
also be aperiodic and based on event criteria. For example, if an
IAB node 400 performs a measurement during a given discovery period
and does not detect any additional IAB nodes, it cannot provide an
updated measurement/detection report to the network in order to
avoid the overhead of such UL transmissions. In another example,
the IAB node 400 can provide a measurement report if newly
discovered IAB nodes 802 are detected, or if the measurement
quantity (e.g., reference signal received power (RSRP/reference
signal received quality (RSRQ)) has changed outside of a configured
range compared to a previous measurement or increases/decreases
compared to an absolute threshold configured by the network. This
can apply to both RRM measurements and reports as well L1-BM
reports.
[0078] Referring now to FIG. 9, illustrates an example schematic
system block diagram of an initiated aperiodic resource link
management according to one or more embodiments. For the purpose of
backhaul link RLM, either SSB or CSI-RS based in-sync
(IS)/out-of-sync (OOS) determinations can be made. However, similar
to the inter-IAB node discovery case, frequent transmissions of the
reference signals by the parent or donor node 902 can increase the
overhead and impact of the scheduling restrictions imposed by the
half-duplex constraint at the child IAB node 400. As a result, the
IAB-MT (e.g., UE function 404) can be configured with both periodic
and aperiodic RLM, where the periodic configuration can use a large
periodicity and the aperiodic configuration can be activated by the
network based on one or more criteria such as CSI feedback, L1-BM
RSRP, RRM measurement reports, or indication of beam failure or
partial beam failure.
[0079] In another alternative embodiment, the IAB-MT (e.g., UE
function 404) can make a request for aperiodic RLM to be configured
using signalling, which can indicate the timing and resource
configuration (including reference signal type). The aperiodic RLM
request can be triggered at the IAB-MT based on criteria such as
link quality metrics derived from periodic IS/OOS reports falling
below a given threshold or based on other measurements such as
CSI/L1-RSRP/RRM measurements. In another alternative the IAB-MT
(e.g., UE function 404) can make the aperiodic RLM request based on
a request from the IAB-DU (e.g., gNode B function 406) to support a
desired IAB node transmission/reception state across the IAB node,
subject to the half-duplex constraint.
[0080] Referring now to FIG. 10, illustrated is an example flow
diagram for a method for radio resource configuration and
measurements for a 5G network according to one or more embodiments.
At element 1000, the method can comprise connecting a mobile device
function (e.g., UE function 404) of the first wireless network
device (e.g., IAB node 400) to a second wireless network device
(e.g., parent IAB node 802). At element 1002, the method can
comprise receiving (e.g., via the IAB node 400) synchronization
signal block data representative of a synchronization signal block
measurement in response to the connecting. At element 1004, the
method can comprise, based on the receiving the synchronization
signal block data, performing (e.g., via the IAB node 400) a radio
resource measurement, wherein the radio resource measurement
comprises a beam management measurement. Additionally, at element
1006, the method can comprise selecting (e.g., via the IAB node

[0084] Referring now to FIG. 13, illustrated is an example block
diagram of an example mobile handset 1300 operable to engage in a
system architecture that facilitates wireless communications
according to one or more embodiments described herein. Although a
mobile handset is illustrated herein, it will be understood that
other devices can be a mobile device, and that the mobile handset
is merely illustrated to provide context for the embodiments of the
various embodiments described herein. The following discussion is
intended to provide a brief, general description of an example of a
suitable environment in which the various embodiments can be
implemented. While the description includes a general context of
computer-executable instructions embodied on a machine-readable
storage medium, those skilled in the art will recognize that the
innovation also can be implemented in combination with other
program modules and/or as a combination of hardware and
software.
[0085] Generally, applications (e.g., program modules) can include
routines, programs, components, data structures, etc., that perform
particular tasks or implement particular abstract data types.
Moreover, those skilled in the art will appreciate that the methods
described herein can be practiced with other system configurations,
including single-processor or multiprocessor systems,
minicomputers, mainframe computers, as well as personal computers,
hand-held computing devices, microprocessor-based or programmable
consumer electronics, and the like, each of which can be
operatively coupled to one or more associated devices
[0086] A computing device can typically include a variety of
machine-readable media. Machine-readable media can be any available
media that can be accessed by the computer and includes both
volatile and non-volatile media, removable and non-removable media.
By way of example and not limitation, computer-readable media can
comprise computer storage media and communication media. Computer
storage media can include volatile and/or non-volatile media,

other medium which can be used to store the desired information and
which can be accessed by the computer. In this regard, the terms
"tangible" or "non-transitory" herein as applied to storage, memory
or computer-readable media, are to be understood to exclude only
propagating transitory signals per se as modifiers and do not
relinquish rights to all standard storage, memory or
computer-readable media that are not only propagating transitory
signals per se.
[0087] Communication media typically embodies computer-readable
instructions, data structures, program modules, or other data in a
modulated data signal such as a carrier wave or other transport
mechanism, and includes any information delivery media. The term
"modulated data signal" means a signal that has one or more of its
characteristics set or changed in such a manner as to encode
information in the signal. By way of example, and not limitation,
communication media includes wired media such as a wired network or
direct-wired connection, and wireless media such as acoustic, RF,
infrared and other wireless media. Combinations of the any of the
above should also be included within the scope of computer-readable
media
[0088] The handset includes a processor 1302 for controlling and
processing all onboard operations and functions. A memory 1304
interfaces to the processor 1302 for storage of data and one or
more applications 1306 (e.g., a video player software, user
feedback component software, etc.). Other applications can include
voice recognition of predetermined voice commands that facilitate
initiation of the user feedback signals. The applications 1306 can
be stored in the memory 1304 and/or in a firmware 1308, and
executed by the processor 1302 from either or both the memory 1304
or/and the firmware 1308. The firmware 1308 can also store startup
code for execution in initializing the handset 1300. A
communications component 1310 interfaces to the processor 1302 to
facilitate wired/wireless communication with external systems,
e.g., cellular networks, VoIP networks, and so on. Here, the
communications component 1310 can also include a suitable cellular
transceiver 1311 (e.g., a GSM transceiver) and/or an unlicensed
transceiver 1313 (e.g., Wi-Fi, WiMax) for corresponding signal
communications. The handset 1300 can be a device such as a cellular
telephone, a PDA with mobile communications capabilities, and
messaging-centric devices. The communications component 1310 also
facilitates communications reception from terrestrial radio
networks (e.g., broadcast), digital satellite radio networks, and
Internet-based radio services networks
[0089] The handset 1300 includes a display 1312 for displaying
text, images, video, telephony functions (e.g., a Caller ID
function), setup functions, and for user input. For example, the
display 1312 can also be referred to as a "screen" that can
accommodate the presentation of multimedia content (e.g., music
metadata, messages, wallpaper, graphics, etc.). The display 1312
can also display videos and can facilitate the generation, editing
and sharing of video quotes. A serial I/O interface 1314 is
provided in communication with the processor 1302 to facilitate
wired and/or wireless serial communications (e.g., USB, and/or IEEE
1394) through a hardwire connection, and other serial input devices
(e.g., a keyboard, keypad, and mouse). This supports updating and
troubleshooting the handset 1300, for example. Audio capabilities
are provided with an audio I/O component 1316, which can include a
speaker for the output of audio signals related to, for example,
indication that the user pressed the proper key or key combination
to initiate the user feedback signal. The audio I/O component 1316
also facilitates the input of audio signals through a microphone to
record data and/or telephony voice data, and for inputting voice
signals for telephone conversations.
[0090] The handset 1300 can include a slot interface 1318 for
accommodating a SIC (Subscriber Identity Component) in the form
factor of a card Subscriber Identity Module (SIM) or universal SIM
1320, and interfacing the SIM card 1320 with the processor 1302.
However, it is to be appreciated that the SIM card 1320 can be
manufactured into the handset 1300, and updated by downloading data
and software.
[0091] The handset 1300 can process IP data traffic through the
communications component 1310 to accommodate IP traffic from an IP
network such as, for example, the Internet, a corporate intranet, a
home network, a person area network, etc., through an ISP or
broadband cable provider. Thus, VoIP traffic can be utilized by the
handset 1300 and IP-based multimedia content can be received in
either an encoded or a decoded format.
[0092] A video processing component 1322 (e.g., a camera) can be
provided for decoding encoded multimedia content. The video
processing component 1322 can aid in facilitating the generation,
editing, and sharing of video quotes. The handset 1300 also
includes a power source 1324 in the form of batteries and/or an AC
power subsystem, which power source 1324 can interface to an
external power system or charging equipment (not shown) by a power
I/O component 1326.
[0093] The handset 1300 can also include a video component 1330 for
processing video content received and, for recording and
transmitting video content. For example, the video component 1330
can facilitate the generation, editing and sharing of video quotes.
A location tracking component 1332 facilitates geographically
locating the handset 1300. As described hereinabove, this can occur
when the user initiates the feedback signal automatically or
manually. A user input component 1334 facilitates the user
initiating the quality feedback signal. The user input component
1334 can also facilitate the generation, editing and sharing of
video quotes. The user input component 1334 can include such
conventional input device technologies such as a keypad, keyboard,
mouse, stylus pen, and/or touch screen, for example.
[0094] Referring again to the applications 1306, a hysteresis
component 1336 facilitates the analysis and processing of
hysteresis data, which is utilized to determine when to associate
with the access point. A software trigger component 1338 can be
provided that facilitates triggering of the hysteresis component
1336 when the Wi-Fi transceiver 1313 detects the beacon of the
access point. A SIP client 1340 enables the handset 1300 to support
SIP protocols and register the subscriber with the SIP registrar
server. The applications 1306 can also include a client 1342 that
provides at least the capability of discovery, play and store of
multimedia content, for example, music.
[0095] The handset 1300, as indicated above related to the
communications component 1310, includes an indoor network radio
transceiver 1313 (e.g., Wi-Fi transceiver). This function supports
the indoor radio link, such as IEEE 802.11, for the dual-mode GSM
handset 1300. The handset 1300 can accommodate at least satellite
radio services through a handset that can combine wireless voice
and digital radio chipsets into a single handheld device.
[0096] Referring now to FIG. 14, illustrated is an example block
diagram of an example computer 1400 operable to engage in a system
architecture that facilitates wireless communications according to
one or more embodiments described herein. The computer 1400 can
provide networking and communication capabilities between a wired
or wireless communication network and a server (e.g., Microsoft
server) and/or communication device. In order to provide additional
context for various aspects thereof, FIG. 14 and the following
discussion are intended to provide a brief, general description of
a suitable computing environment in which the various aspects of
the innovation can be implemented to facilitate the establishment
of a transaction between an entity and a third party. While the
description above is in the general context of computer-executable
instructions that can run on one or more computers, those skilled
in the art will recognize that the innovation also can be
implemented in combination with other program modules and/or as a
combination of hardware and software.
[0097] Generally, program modules include routines, programs,
components, data structures, etc., that perform particular tasks or
implement particular abstract data types. Moreover, those skilled
in the art will appreciate that the various methods can be
practiced with other computer system configurations, including
single-processor or multiprocessor computer systems, minicomputers,
mainframe computers, as well as personal computers, hand-held
computing devices, microprocessor-based or programmable consumer
electronics, and the like, each of which can be operatively coupled
to one or more associated devices.
[0098] The illustrated aspects of the innovation can also be
practiced in distributed computing environments where certain tasks
are performed by remote processing devices that are linked through
a communications network. In a distributed computing environment,
program modules can be located in both local and remote memory
storage devices.
[0099] Computing devices typically include a variety of media,
which can include computer-readable storage media or communications
media, which two terms are used herein differently from one another
as follows.
[0100] Computer-readable storage media can be any available storage
media that can be accessed by the computer and includes both
volatile and nonvolatile media, removable and non-removable media.
By way of example, and not limitation, computer-readable storage
media can be implemented in connection with any method or
technology for storage of information such as computer-readable
instructions, program modules, structured data, or unstructured
data. Computer-readable storage media can include, but are not
limited to, RAM, ROM, EEPROM, flash memory or other memory
technology, CD-ROM, digital versatile disk (DVD) or other optical
disk storage, magnetic cassettes, magnetic tape, magnetic disk
storage or other magnetic storage devices, or other tangible and/or
non-transitory media which can be used to store desired
information. Computer-readable storage media can be accessed by one
or more local or remote computing devices, e.g., via access
requests, queries or other data retrieval protocols, for a variety
of operations with respect to the information stored by the
medium.
[0101] Communications media can embody computer-readable
instructions, data structures, program modules, or other structured
or unstructured data in a data signal such as a modulated data
signal, e.g., a carrier wave or other transport mechanism, and
includes any information delivery or transport media. The term
"modulated data signal" or signals refers to a signal that has one
or more of its characteristics set or changed in such a manner as
to encode information in one or more signals. By way of example,
and not limitation, communication media include wired media, such
as a wired network or direct-wired connection, and wireless media
such as acoustic, RF, infrared and other wireless media.
[0102] The techniques described herein can be applied to any device
or set of devices (machines) capable of running programs and
processes. It can be understood, therefore, that servers including
physical and/or virtual machines, personal computers, laptops,
handheld, portable and other computing devices and computing
objects of all kinds including cell phones, tablet/slate computers,
gaming/entertainment consoles and the like are contemplated for use
in connection with various implementations including those
exemplified herein. Accordingly, the general purpose computing
mechanism described below with reference to FIG. 14 is but one
example of a computing device.
[0103] In order to provide a context for the various aspects of the
disclosed subject matter, FIG. 14 and the following discussion, are
intended to provide a brief, general description of a suitable
environment in which the various aspects of the disclosed subject
matter can be implemented. While the subject matter has been
described above in the general context of computer-executable
instructions of a computer program that runs on a computer and/or
computers, those skilled in the art will recognize that the
disclosed subject matter also can be implemented in combination
with other program modules. Generally, program modules include
routines, programs, components, data structures, etc. that perform
particular tasks and/or implement particular abstract data
types.
[0104] In the subject specification, terms such as "store,"
"storage," "data store," data storage," "database," and
substantially any other information storage component relevant to
operation and functionality of a component, refer to "memory
components," or entities embodied in a "memory" or components
comprising the memory. It will be appreciated that the memory
components described herein can be either volatile memory or
nonvolatile memory, or can include both volatile and nonvolatile
memory, by way of illustration, and not limitation, volatile memory
1420 (see below), non-volatile memory 1422 (see below), disk
storage 1424 (see below), and memory storage 1446 (see below).
Further, nonvolatile memory can be included in read only memory
(ROM), programmable ROM (PROM), electrically programmable ROM
(EPROM), electrically erasable ROM (EEPROM), or flash memory.
Volatile memory can include random access memory (RAM), which acts
as external cache memory. By way of illustration and not
limitation, RAM is available in many forms such as synchronous RAM
(SRAM), dynamic RAM (DRAM), synchronous DRAM (SDRAM), double data
rate SDRAM (DDR SDRAM), enhanced SDRAM (ESDRAM), Synchlink DRAM
(SLDRAM), and direct Rambus RAM (DRRAM). Additionally, the
disclosed memory components of systems or methods herein are
intended to comprise, without being limited to comprising, these
and any other suitable types of memory.
[0105] Moreover, it will be noted that the disclosed subject matter
can be practiced with other computer system configurations,
including single-processor or multiprocessor computer systems,
mini-computing devices, mainframe computers, as well as personal
computers, hand-held computing devices (e.g., PDA, phone, watch,
tablet computers, netbook computers, . . . ), microprocessor-based
or programmable consumer or industrial electronics, and the like.
The illustrated aspects can also be practiced in distributed
computing environments where tasks are performed by remote
processing devices that are linked through a communications
network; however, some if not all aspects of the subject disclosure
can be practiced on stand-alone computers. In a distributed
computing environment, program modules can be located in both local
and remote memory storage devices.
[0106] FIG. 14 illustrates a block diagram of a computing system
1400 operable to execute the disclosed systems and methods in
accordance with an embodiment. Computer 1412, which can be, for
example, part of the hardware of system 1420, includes a processing
unit 1414, a system memory 1416, and a system bus 1418. System bus
1418 couples system components including, but not limited to,
system memory 1416 to processing unit 1414. Processing unit 1414
can be any of various available processors. Dual microprocessors
and other multiprocessor architectures also can be employed as
processing unit 1414.
[0107] System bus 1418 can be any of several types of bus

Graphics Port (AGP), Personal Computer Memory Card International
Association bus (PCMCIA), Firewire (IEEE 1494), and Small Computer
Systems Interface (SCSI).
[0108] System memory 1416 can include volatile memory 1420 and
nonvolatile memory 1422. A basic input/output system (BIOS),
containing routines to transfer information between elements within
computer 1412, such as during start-up, can be stored in
nonvolatile memory 1422. By way of illustration, and not
limitation, nonvolatile memory 1422 can include ROM, PROM, EPROM,
EEPROM, or flash memory. Volatile memory 1420 includes RAM, which
acts as external cache memory. By way of illustration and not
limitation, RAM is available in many forms such as SRAM, dynamic
RAM (DRAM), synchronous DRAM (SDRAM), double data rate SDRAM (DDR
SDRAM), enhanced SDRAM (ESDRAM), Synchlink DRAM (SLDRAM), Rambus
direct RAM (RDRAM), direct Rambus dynamic RAM (DRDRAM), and Rambus
dynamic RAM (RDRAM).
[0109] Computer 1412 can also include removable/non-removable,
volatile/non-volatile computer storage media. FIG. 14 illustrates,
for example, disk storage 1424. Disk storage 1424 includes, but is
not limited to, devices like a magnetic disk drive, floppy disk
drive, tape drive, flash memory card, or memory stick. In addition,
disk storage 1424 can include storage media separately or in
combination with other storage media including, but not limited to,
an optical disk drive such as a compact disk ROM device (CD-ROM),
CD recordable drive (CD-R Drive), CD rewritable drive (CD-RW Drive)
or a digital versatile disk ROM drive (DVD-ROM). To facilitate
connection of the disk storage devices 1424 to system bus 1418, a
removable or non-removable interface is typically used, such as
interface 1426.
[0110] Computing devices typically include a variety of media,
which can include computer-readable storage media or communications
media, which two terms are used herein differently from one another
as follows.
[0111] Computer-readable storage media can be any available storage
media that can be accessed by the computer and includes both
volatile and nonvolatile media, removable and non-removable media.
By way of example, and not limitation, computer-readable storage
media can be implemented in connection with any method or
technology for storage of information such as computer-readable
instructions, program modules, structured data, or unstructured
data. Computer-readable storage media can include, but are not
limited to, random access memory (RAM), read only memory (ROM),
electrically erasable programmable read only memory (EEPROM), flash
memory or other memory technology, solid state drive (SSD) or other
solid-state storage technology, compact disk read only memory (CD
ROM), digital versatile disk (DVD), Blu-ray disc or other optical
disk storage, magnetic cassettes, magnetic tape, magnetic disk
storage or other magnetic storage devices or other tangible and/or
non-transitory media which can be used to store desired
information. In this regard, the terms "tangible" or
"non-transitory" herein as applied to storage, memory or
computer-readable media, are to be understood to exclude only
propagating transitory signals per se as modifiers and do not
relinquish rights to all standard storage, memory or
computer-readable media that are not only propagating transitory
signals per se. In an aspect, tangible media can include
non-transitory media wherein the term "non-transitory" herein as
may be applied to storage, memory or computer-readable media, is to
be understood to exclude only propagating transitory signals per se
as a modifier and does not relinquish coverage of all standard
storage, memory or computer-readable media that are not only
propagating transitory signals per se. For the avoidance of doubt,
the term "computer-readable storage device" is used and defined
herein to exclude transitory media. Computer-readable storage media
can be accessed by one or more local or remote computing devices,
e.g., via access requests, queries or other data retrieval
protocols, for a variety of operations with respect to the
information stored by the medium.
[0112] Communications media typically embody computer-readable
instructions, data structures, program modules or other structured
or unstructured data in a data signal such as a modulated data
signal, e.g., a carrier wave or other transport mechanism, and
includes any information delivery or transport media. The term
"modulated data signal" or signals refers to a signal that has one
or more of its characteristics set or changed in such a manner as
to encode information in one or more signals. By way of example,
and not limitation, communication media include wired media, such
as a wired network or direct-wired connection, and wireless media
such as acoustic, RF, infrared and other wireless media.
[0113] It can be noted that FIG. 14 describes software that acts as
an intermediary between users and computer resources described in
suitable operating environment 1400. Such software includes an
operating system 1428. Operating system 1428, which can be stored
on disk storage 1424, acts to control and allocate resources of
computer system 1412. System applications 1430 take advantage of
the management of resources by operating system 1428 through
program modules 1432 and program data 1434 stored either in system
memory 1416 or on disk storage 1424. It is to be noted that the
disclosed subject matter can be implemented with various operating
systems or combinations of operating systems.
[0114] A user can enter commands or information into computer 1412
through input device(s) 1436. As an example, a mobile device and/or
portable device can include a user interface embodied in a touch
sensitive display panel allowing a user to interact with computer
1412. Input devices 1436 include, but are not limited to, a
pointing device such as a mouse, trackball, stylus, touch pad,
keyboard, microphone, joystick, game pad, satellite dish, scanner,
TV tuner card, digital camera, digital video camera, web camera,
cell phone, smartphone, tablet computer, etc. These and other input
devices connect to processing unit 1414 through system bus 1418 by
way of interface port(s) 1438. Interface port(s) 1438 include, for
example, a serial port, a parallel port, a game port, a universal
serial bus (USB), an infrared port, a Bluetooth port, an IP port,
or a logical port associated with a wireless service, etc. Output
device(s) 1440 and a move use some of the same type of ports as
input device(s) 1436.
[0115] Thus, for example, a USB port can be used to provide input
to computer 1412 and to output information from computer 1412 to an
output device 1440. Output adapter 1442 is provided to illustrate
that there are some output devices 1440 like monitors, speakers,
and printers, among other output devices 1440, which use special
adapters. Output adapters 1442 include, by way of illustration and
not limitation, video and sound cards that provide means of
connection between output device 1440 and system bus 1418. It
should be noted that other devices and/or systems of devices
provide both input and output capabilities such as remote
computer(s) 1444.
[0116] Computer 1412 can operate in a networked environment using
logical connections to one or more remote computers, such as remote
computer(s) 1444. Remote computer(s) 1444 can be a personal
computer, a server, a router, a network PC, cloud storage, cloud
service, a workstation, a microprocessor based appliance, a peer
device, or other common network node and the like, and typically
includes many or all of the elements described relative to computer
1412.
[0117] For purposes of brevity, only a memory storage device 1446
is illustrated with remote computer(s) 1444. Remote computer(s)
1444 is logically connected to computer 1412 through a network
interface 1448 and then physically connected by way of
communication connection 1450. Network interface 1448 encompasses
wire and/or wireless communication networks such as local-area
networks (LAN) and wide-area networks (WAN). LAN technologies
include Fiber Distributed Data Interface (FDDI), Copper Distributed
Data Interface (CDDI), Ethernet, Token Ring and the like. WAN
technologies include, but are not limited to, point-to-point links,
circuit-switching networks like Integrated Services Digital
Networks (ISDN) and variations thereon, packet switching networks,
and Digital Subscriber Lines (DSL). As noted below, wireless
technologies may be used in addition to or in place of the
foregoing.
[0118] Communication connection(s) 1450 refer(s) to
hardware/software employed to connect network interface 1448 to bus
1418. While communication connection 1450 is shown for illustrative
clarity inside computer 1412, it can also be external to computer
1412. The hardware/software for connection to network interface
1448 can include, for example, internal and external technologies
such as modems, including regular telephone grade modems, cable
modems and DSL modems, ISDN adapters, and Ethernet cards.

[0123] As used in this application, the terms "component,"
"system," "platform," "layer," "selector," "interface," and the
like are intended to refer to a computer-related entity or an
entity related to an operational apparatus with one or more
specific functionalities, wherein the entity can be either
hardware, a combination of hardware and software, software, or
software in execution. As an example, a component may be, but is
not limited to being, a process running on a processor, a
processor, an object, an executable, a thread of execution, a
program, and/or a computer. By way of illustration and not
limitation, both an application running on a server and the server
can be a component. One or more components may reside within a
process and/or thread of execution and a component may be localized
on one computer and/or distributed between two or more computers.
In addition, these components can execute from various computer
readable media, device readable storage devices, or machine
readable media having various data structures stored thereon. The
components may communicate via local and/or remote processes such
as in accordance with a signal having one or more data packets
(e.g., data from one component interacting with another component
in a local system, distributed system, and/or across a network such
as the Internet with other systems via the signal). As another
example, a component can be an apparatus with specific
functionality provided by mechanical parts operated by electric or
electronic circuitry, which is operated by a software or firmware
application executed by a processor, wherein the processor can be
internal or external to the apparatus and executes at least a part
of the software or firmware application. As yet another example, a
component can be an apparatus that provides specific functionality
through electronic components without mechanical parts, the
electronic components can include a processor therein to execute
software or firmware that confers at least in part the
functionality of the electronic components.
[0124] In addition, the term "or" is intended to mean an inclusive
"or" rather than an exclusive "or." That is, unless specified
otherwise, or clear from context, "X employs A or B" is intended to
mean any of the natural inclusive permutations. That is, if X
employs A; X employs B; or X employs both A and B, then "X employs
A or B" is satisfied under any of the foregoing instances.
Moreover, articles "a" and "an" as used in the subject
specification and annexed drawings should generally be construed to
mean "one or more" unless specified otherwise or clear from context
to be directed to a singular form.
[0125] Moreover, terms like "user equipment (UE)," "mobile
station," "mobile," subscriber station," "subscriber equipment,"
"access terminal," "terminal," "handset," and similar terminology,
refer to a wireless device utilized by a subscriber or user of a
wireless communication service to receive or convey data, control,
voice, video, sound, gaming, or substantially any data-stream or
signaling-stream. The foregoing terms are utilized interchangeably
in the subject specification and related drawings. Likewise, the
terms "access point (AP)," "base station," "NodeB," "evolved Node B
(eNodeB)," "home Node B (HNB)," "home access point (HAP)," "cell
device," "sector," "cell," and the like, are utilized
interchangeably in the subject application, and refer to a wireless
network component or appliance that serves and receives data,
control, voice, video, sound, gaming, or substantially any
data-stream or signaling-stream to and from a set of subscriber
stations or provider enabled devices. Data and signaling streams
can include packetized or frame-based flows.
[0126] Additionally, the terms "core-network", "core", "core
carrier network", "carrier-side", or similar terms can refer to
components of a telecommunications network that typically provides
some or all of aggregation, authentication, call control and
switching, charging, service invocation, or gateways. Aggregation
can refer to the highest level of aggregation in a service provider
network wherein the next level in the hierarchy under the core
nodes is the distribution networks and then the edge networks. UEs
do not normally connect directly to the core networks of a large
service provider but can be routed to the core by way of a switch
or radio area network. Authentication can refer to determinations
regarding whether the user requesting a service from the telecom
network is authorized to do so within this network or not. Call
control and switching can refer determinations related to the
future course of a call stream across carrier equipment based on
the call signal processing. Charging can be related to the
collation and processing of charging data generated by various
network nodes. Two common types of charging mechanisms found in
present day networks can be prepaid charging and postpaid charging.
Service invocation can occur based on some explicit action (e.g.,
call transfer) or implicitly (e.g., call waiting). It is to be
noted that service "execution" may or may not be a core network
functionality as third party network/nodes may take part in actual
service execution. A gateway can be present in the core network to
access other networks. Gateway functionality can be dependent on
the type of the interface with another network.
[0127] Furthermore, the terms "user," "subscriber," "customer,"
"consumer," "prosumer," "agent," and the like are employed
interchangeably throughout the subject specification, unless
context warrants particular distinction(s) among the terms. It
should be appreciated that such terms can refer to human entities
or automated components (e.g., supported through artificial
intelligence, as through a capacity to make inferences based on
complex mathematical formalisms), that can provide simulated
vision, sound recognition and so forth.
[0128] Aspects, features, or advantages of the subject matter can
be exploited in substantially any, or any, wired, broadcast,
wireless telecommunication, radio technology or network, or
combinations thereof. Non-limiting examples of such technologies or
networks include Geocast technology; broadcast technologies (e.g.,
sub-Hz, ELF, VLF, LF, MF, HF, VHF, UHF, SHF, THz broadcasts, etc.);
Ethernet; X.25; powerline-type networking (e.g., PowerLine AV
Ethernet, etc.); femto-cell technology; Wi-Fi; Worldwide
Interoperability for Microwave Access (WiMAX); Enhanced General
Packet Radio Service (Enhanced GPRS); Third Generation Partnership
Project (3GPP or 3G) Long Term Evolution (LTE); 3GPP Universal
Mobile Telecommunications System (UMTS) or 3GPP UMTS; Third
Generation Partnership Project 2 (3GPP2) Ultra Mobile Broadband
(UMB); High Speed Packet Access (HSPA); High Speed Downlink Packet
Access (HSDPA); High Speed Uplink Packet Access (HSUPA); GSM
Enhanced Data Rates for GSM Evolution (EDGE) Radio Access Network
(RAN) or GERAN; UMTS Terrestrial Radio Access Network (UTRAN); or
LTE Advanced.
[0129] What has been described above includes examples of systems
and methods illustrative of the disclosed subject matter. It is, of
course, not possible to describe every combination of components or
methods herein. One of ordinary skill in the art may recognize that
many further combinations and permutations of the disclosure are
possible. Furthermore, to the extent that the terms "includes,"
"has," "possesses," and the like are used in the detailed
description, claims, appendices and drawings such terms are
intended to be inclusive in a manner similar to the term
"comprising" as "comprising" is interpreted when employed as a
transitional word in a claim.
