[0042] FIG. 1 shows a schematic architectural diagram of a wireless

disclosure. The wireless communication system 100 may include a
network device 110. The network device 110 may be a device that

provide communication coverage for a particular geographic area and
may communicate with the terminal device (e.g., UE) located within
the coverage area. Optionally, the network device 110 may be a base

CDMA system, or may be a base station (NodeB, NB) in the WCDMA
system, or may be an evolved base station (Evolutional Node B, eNB

station, an access point, an in-vehicle device, a wearable device,

[0043] The wireless communication system 100 also includes at least
one terminal device 120 located within the coverage of the network
device 110. The terminal device 120 may be mobile or fixed.
Optionally, the terminal device 120 may refer to an access
terminal, a User Equipment (UE), a subscriber unit, a subscriber

device with wireless communication function, a computing device or
other processing devices connected to a wireless modem, an

[0044] Optionally, Device to Device (D2D) communication may be

[0045] Optionally, the 5G system or network may also be referred to
as a New Radio (NR) system or network.
[0046] As shown in FIG. 1, optionally, the wireless communication
system 100 may include a plurality of network devices and may
include other numbers of terminal devices in the coverage of the
network device, which is not limited by the embodiment of the
present disclosure.
[0047] In the carrier aggregation scenario, PDCP may support the
data duplication function, that is, by utilizing the function of
duplicating data of PDCP, the duplicated data corresponds to two or
more logical channels, and finally it is ensured that a plurality
of duplicated PDCP PDUs (they are the same) are capable of being
transmitted in different aggregation carriers of the physical
layer, so as to achieve frequency diversity gain and thus to
improve reliability of data transmission.
[0048] For ease of understanding, how to schedule the duplicated
data on different physical carriers will be briefly described below
with reference to FIG. 2. As shown in FIG. 2, the PDCP layer has a
split bearer duplication function, and duplicates and packages the
data process of the PDCP Service Data Unit (SDU) into PDCP PDU1 and
PDCP PDU2, PDCP PDU1 and PDCP PDU2 having the same content, that
is, the carried data (payload) and the header being the same. PDCP
PDU1 and PDCP PDU2 are respectively mapped to different Radio Link
Control (RLC) entities, and the RLC entities place PDCP PDU1 and
PDCP PDU2 on different logical channels (a logical channel 1 and a
logical channel 2). For a Media Access Control (MAC), after
learning which logical channels transmit the duplicated data of the
same PDCP PDU, the duplicated data is transmitted on different
carriers through different Hybrid Automatic Repeat reQuest (HARQ)
entities. For example, the duplicated data carried in the logical
channel 1 is transmitted on the physical carrier 1 through the HARQ
entity 1, and the duplicated data carried in the logical channel 2
is transmitted on the physical carrier 2 through the HARQ entity
2.
[0049] Those skilled in the art should understand that the PDCP
data duplication function may be configured based on a Radio Bearer
(RB), that is, different RBs may be configured to support PDCP
duplication data transmission, or no PDCP duplication data
transmission is configured.
[0050] RB is a general term for a series of protocol entities and
configurations allocated by a base station for the terminal device,
including a PDCP protocol entity, an RLC protocol entity, a series
of resources allocated by a MAC and a physical layer (PHY), and the
like. The RB includes a Signaling Radio Bearer (SRB) and a Data
Radio Bearer (DRB). The SRB is a channel through which the
signaling message of the system is actually transmitted. The DRB is
a channel through which the user data is actually transmitted.
[0051] FIG. 3 is a schematic flowchart of a method 300 for wireless
communication according to an embodiment of the present disclosure.
As shown in FIG. 3, the method 300 includes some or all of the
following steps.
[0052] In 310, the terminal device receives first indication
information sent by the network device, where the first indication
information is used to instruct the terminal device to stop the
duplication transmission of the data of one or more radio
bearers.
[0053] In 320, the terminal device maps, according to the first
indication information, a first logical channel to all carriers of
a plurality of carriers, where the plurality of carriers are all
carriers in carriers configured by the network device for the
terminal device.
[0054] Specifically, in the embodiments of the present disclosure,
by receiving the indication information sent by the network device,
the terminal device stops the duplication transmission of data of
one or more radio bearers, and maps the first logical channel to
all the carriers in the plurality of carriers configured by the
network device, so that the first logical channel can transmit data
on the plurality of carriers, thereby increasing the rate of data
transmission.
[0055] It should be understood that the first logical channel is a
logical channel under one or more radio bearers. When the radio
bearer is one, the first logical channel may be a plurality of
logical channels under the one radio bearer, or may be one logical
channel under the one radio bearer; and when the number of radio
bearers is multiple, the first logical channel may be one logical
channel under each radio bearer of the plurality of radio bearers,
or may be a plurality of logical channels under each of the
plurality of radio bearers.
[0056] That is, the first logical channel may be a plurality of
logical channels, or may be one logical channel.
[0057] Optionally, after receiving the first indication
information, the terminal device may immediately release the
mapping relationship established when transmitting the data by
using the duplication data transmission manner.
[0058] For example, when the data is transmitted using the
duplication data transmission manner, the logical channel LCH 1 is
used to transmit data information, and the logical channel LCH 2 is
used to transmit the duplicated data of the data information of the
logical channel LCH 1. At this time, the logical channel LCH 1 is
mapped to a carrier 1, and the logical channel 2 is mapped to a
carrier 2. After the terminal device receives the first indication
information, the terminal device may immediately release the above
relationship between the logical channel LCH 1 and the logical
channel LCH 2. After the release, the logical channel LCH 2 is no
longer used to transmit the duplicated data of the data of the
logical channel LCH 1, and the terminal device may also release the
mapping relationship between the logical channel LCH 1 and the
carrier 1 and the mapping relationship between the logical channel
LCH 2 and the carrier 2.
[0059] It should be understood that the "release" here refers to
removing the mapping relationship pre-configured by the network
device, or the mapping relationship pre-configured by the network
device being no longer existing.
[0060] That is to say, after the terminal device receives the first
indication information, the terminal device may release or remove
the mapping relationship established when transmitting the data by
using the duplication transmission mode by default.
[0061] Optionally, the first indication information may be carried
in a Media Access Control Control Element (MAC CE).
[0062] Optionally, after the terminal device receives the first
indication information, the terminal device maps the first logical
channel to all carriers of the plurality of carriers. At this time,
the terminal device may not transmit data through the second
logical channel, and then the terminal device may not care whether
to map the second logical channel onto all of the plurality of
carriers.
[0063] Optionally, after the terminal device receives the first
indication information, and when the terminal device uses the
second logical channel to transmit data, the data transmitted by
the second logical channel is different from the data transmitted
by the first logical channel. At this time, the terminal device may
map the first logical channel to all of the plurality of carriers,
or may map the second logical channel to all of the plurality of
carriers.
[0064] That is, since the terminal device uses the first logical
channel and the second logical channel to transmit different data,
the terminal device may map the first logical channel and the
second logical channel to all carriers respectively, and even the
carriers to which the first logical channel and the second channel
are mapped are the same carrier, the transmission of data on the
first logical channel and the second logical channel is not
affected.
[0065] Optionally, in some embodiments, before the terminal device
maps the first logical channel to all of the plurality of carriers,
the terminal device may first release the relationship between the
first logical channel and the second logical channel. Before
releasing the relationship between the first logical channel and
the second logical channel, the second logical channel is a logical
channel for transmitting duplicated data of data of the first
logical channel, and after releasing the relationship between the
first logical channel and the second logical channel, the second
logical channel may be used to transmit data different from data of
the first logical channel, or may not transmit data.
[0066] It should be understood that "release" herein also refers to
removing the pre-configured mapping relationship of the network,
for example, removing the mapping relationship of transmitting the
duplicated data of the data of the first logical channel by the
second logical channel. After the release, the data transmitted by
the second logical channel is not related to the data transmitted
by the first logical channel, that is, the data transmitted by the
second logical channel may be different from the data transmitted
by the first logical channel, or no data is transmitted by the
second logical channel, which is not limited by the embodiments of
the present disclosure.
[0067] It should be understood that the relationship between the
first logical channel and the second logical channel may be
configured by the network device to the terminal device using Radio
Resource Control (RRC) signaling.
[0068] Optionally, before the terminal device maps the first
logical channel to all of the plurality of carriers, the terminal
device may further release a pre-configured mapping relationship
between the first logical channel and the first carrier.
[0069] It should be understood that "release" herein also means
removing the mapping relationship pre-configured by the network
device, or means that the mapping relationship previously
configured by the network device does not exist.
[0070] That is, the action of releasing the pre-configured mapping
relationship of the network device by the terminal device may be
realistic, that is, after receiving the first indication
information, the terminal device may perform the operation of
releasing the mapping relationship according to the first
indication information, or the action may be the default of the
terminal device, that is, after the terminal device receives the
first indication information, it is default by the terminal device
that the mapping relationship previously configured for the
terminal device by the network device does not exist, which is not
limited in the embodiments of the present disclosure.
[0071] It should be understood that the pre-configured mapping
relationship between the first logical channel and the first
carrier may be configured by the network device to the terminal
device by using RRC signaling. For example, the network device may
configure the logical channel LCH 1 to the carrier 1, and configure
the logical channel LCH 2 to the carrier 2 through the RRC
signaling, thereby avoiding confusion of data transmission due to
that the contents of the data information transmitted by the
logical channels are the same when different logical channels
correspond to the same carrier, and improving the accuracy of data
transmission.
[0072] It should be understood that the first carrier may be a
carrier or a group of carriers, which is not limited in the
embodiments of the present disclosure.
[0073] Therefore, the pre-configured mapping relationship between
the first logical channel and the first carrier may be that one
first logical channel is configured with one group of first
carriers, or one first logical channel is configured with one first
carrier, or each of a plurality of first logical channels is
configured with one group of first carriers, or each of the
plurality of first logical channels is configured with one first
carrier, or other possible configurations, which are not limited by
the embodiments of the present disclosure.
[0074] Optionally, before the terminal device maps the second
logical channel to all of the plurality of carriers, the terminal
device may further release the pre-configured mapping relationship
between the second logical channel and the second carrier.
[0075] It should be understood that the data transmitted by the
second logical channel herein may be the same as the data
transmitted by the first logical channel, or may be different from
the data transmitted by the first logical channel.
[0076] It should be understood that when the terminal device does
not use the second logical channel to transmit data, the
pre-configured mapping relationship between the second logical
channel and the second carrier may not be released.
[0077] It should be understood that the pre-configured mapping
relationship between the second logical channel and the second
carrier may also be configured by the network device to the
terminal device through RRC signaling.
[0078] It should also be understood that the second carrier may be
a group of carriers or one carrier.
[0079] That is, the pre-configured mapping relationship between the
second logical channel and the second carrier may be that one
second logical channel is configured with a group of second
carriers, or one second logical channel is configured with one
second carrier, or each of the plurality of second logical channels
is configured with one group of second carriers, or each of the
plurality of second logical channels is configured with one second
carrier.
[0080] When the data is transmitted by using the duplication
transmission mode, the first carrier and the second carrier are
different carriers or the first carrier and the second carrier are
different groups of carriers, thereby avoiding confusion in data
transmission due to that the terminal device transmits the same
data on the same carrier or the same group of carriers, and
ensuring the reliability of data transmission.
[0081] Optionally, in some embodiments, after the terminal device
maps the first logical channel to all carriers of the plurality of
carriers, the terminal device may further send second indication
information to the network device, where the second indication
information is used to indicate that the terminal device has mapped
the first logical channel to all of the plurality of carriers.
[0082] Optionally, the second indication information is further
used to indicate that the terminal device has mapped the second
logical channel to all carriers of the plurality of carriers.
[0083] That is, after the terminal device maps the first logical
channel to all carriers and/or after the terminal device maps the
second logical channel to all carriers, the terminal device may
notify the network device of such mapping relationship, so that the
network device knows the mapping relationship of the current first
logical channel and/or the mapping relationship of the second
logical channel; in this way, it is possible to prevent the network
device from repeating sending the first indication information to
the terminal device in the case that the network device does not
know the mapping relationship between the first logical channel
and/or the second logical channel, which can reduce signaling
overhead and reduce energy consumption.
[0084] Optionally, the second indication information may be a local
variable maintained by the terminal device at the MAC layer, where
the local variable corresponds to the logical channel, for example,
when the local variable corresponding to the first logical channel
is "0", it may be used to indicate to map the first logical channel
to all of the plurality of carriers, and when the local variable
corresponding to the second logical channel is "0", it may be used
to indicate to map the second logical channel to all of the
plurality of carriers.
[0085] Optionally, after the terminal device receives the first
indication information, the terminal device may choose to
immediately map the first logical channel to all carriers, or
immediately map the first logical channel and the second logical
channel to all of the carriers, respectively, or may map the first
logical channel to all carriers after a preset time interval, or
map the first logical channel and the second logical channel to all
of the carriers respectively after a preset time interval.
[0086] That is, the terminal device may determine the time at which
the first logical channel and/or the second logical channel are
mapped to all carriers according to the time of receiving the first
indication information.
[0087] For example, if the terminal device receives the first
indication information on the n.sup.th subframe, the terminal
device may map the first logical channel to all carriers on the
n.sup.th subframe, and the terminal device may also map the first
logical channel to all carriers on the (n+k).sup.th subframe, where
k may be a preset time interval.
[0088] FIG. 4 is a schematic flowchart of a method 400 for wireless
communication according to an embodiment of the present disclosure.
As shown in FIG. 4, the method 400 includes some or all of the
following steps.
[0089] In 410, the network device sends first indication
information to the terminal device.
[0090] Optionally, the first indication information is used to
instruct the terminal device to stop duplication transmission of
data of one or more radio bearers.
[0091] Optionally, after the terminal device receives the first
indication information, it may be deemed by default that the data
has been stopped to be transmitted by using the duplication
transmission. In this case, the terminal device may release the
data mapping relationship established when the data is transmitted
by using the duplication transmission.
[0092] After the terminal device receives the first indication
information, the terminal device may default that the mapping
relationship previously configured by the network device does not
exist, and it is unnecessary for the terminal device to perform the
operation of releasing the mapping relationship, or the terminal
device may release the mapping relationship pre-configured by the
network device according to the first indication information. In
the method 400, the mapping relationship pre-configured by the
network device being released by the terminal device according to
the first indication information is taken as an example, and the
embodiments of the present disclosure are not limited thereto.
[0093] It should be understood that the releasing the mapping
relationship may be to release the mapping relationship between the
first logical channel and the second logical channel, or to release
the pre-configured mapping relationship between the first logical
channel and the first carrier, or to release the pre-configured
mapping relationship between the second logical channel and the
second carrier.
[0094] It should also be understood that "release" herein may be
understood as removing the mapping relationship pre-configured by
the network device, or the mapping relationship pre-configured by
the network device no longer exists.
[0095] In 420, the terminal device releases a relationship between
a first logical channel and a second logical channel according to
the first indication information.
[0096] It should be understood that the relationship between the
first logical channel and the second logical channel may be
pre-configured by the network device to the terminal device through
RRC signaling.
[0097] Optionally, before releasing the relationship between the
first logical channel and the second logical channel, the second
logical channel is configured to transmit the duplicated data of
the data of the first logical channel, and after releasing the
relationship between the first logical channel and the second
logical channel, the second logical channel may transmit data
different from the first logical channel, or may not transmit data,
which is not limited by the embodiments of the present
disclosure.
[0098] It should be understood that the "release" refers to
removing the mapping relationship pre-configured by the network
device, or the mapping relationship pre-configured by the network
device no longer exists.
[0099] In 430, the terminal device releases, according to the first
indication information, a pre-configured mapping relationship
between the first logical channel and a first carrier.
[0100] It should be understood that the pre-configured mapping
relationship between the first logical channel and the first
carrier may be configured by the network device to the terminal
device by using RRC signaling.
[0101] It should be understood that the first carrier may be one
carrier or a group of carriers, which is not limited in the
embodiments of the present disclosure.
[0102] Therefore, the configured mapping relationship between the
first logical channel and the first carrier may be that one first
logical channel is configured with one group of first carriers, or
one first logical channel is configured with one first carrier, or
each of a plurality of first logical channels is configured with
one group of first carriers, or each of the plurality of first
logical channels is configured with one first carrier.
[0103] It should be understood that the "release" here refers to
relieving the mapping relationship pre-configured by the network
device, or the mapping relationship pre-configured by the network
device no longer exists.
[0104] In 440, the terminal device releases, according to the first
indication information, a pre-configured mapping relationship
between the second logical channel and a second carrier.
[0105] It should be understood that the pre-configured mapping
relationship between the second logical channel and the second
carrier may also be configured by the network device to the
terminal device through RRC signaling.
[0106] It should also be understood that the second carrier may be
a group of carriers or one carrier.
[0107] That is, the pre-configured mapping relationship between the
second logical channel and the second carrier may be that one
second logical channel is configured with one group of second
carriers, or one second logical channel is configured with one
second carrier, or each of the plurality of second logical channels
is configured with one group of second carriers, or each of the
plurality of second logical channels is configured with one second
carrier.
[0108] It should also be understood that the step 440 is optional.
When the terminal device does not need to use the second logical
channel to transmit data, the terminal device may not release the
mapping relationship between the second logical channel and the
second carrier.
[0109] It should also be understood that there is no inevitable
sequence between steps 420, 430, and 440, and steps 420, 430, and
440 are optional, that is, the terminal device may not perform the
above three steps, and when the terminal device receives the first
indication information, it may be defaulted that the mapping
relationship has been released. In the embodiments of the present
disclosure, the method 400 is described using an example that the
method 400 includes the above steps 420, 430 and 440, but the
embodiments of the present disclosure are not limited thereto.
[0110] In 450, the terminal device maps the first logical channel
to all carriers of a plurality of carriers according to the first
indication information.
[0111] It should be understood that the plurality of carriers are
all carriers in the carriers configured by the network device to
the terminal device.
[0112] In 460, the terminal device maps the second logical channel
to all carriers of the plurality of carriers according to the first
indication information.
[0113] It should be understood that the step 460 is also optional.
When the terminal device uses the second logical channel to
transmit data, and the data transmitted by the second logical
channel is different from the data transmitted by the first logical
channel, the terminal device may map the second logical channel to
all carriers, and when the second logical channel is not used to
transmit data, the step 460 may not be included in the method
400.
[0114] It should also be understood that when the terminal device
transmits data different from the data transmitted by the first
logical channel using the second logical channel, there is no
necessary sequence between the above steps 450 and 460.
[0115] Optionally, after the terminal device receives the first
indication information, the terminal device may choose to
immediately map the first logical channel to all carriers, or
immediately map the first logical channel and the second logical
channel to all of the carriers, respectively, or immediately map
the first logical channel and the second logical channel to all of
the carriers, respectively, or may map the first logical channel to
all carriers after a preset time interval, or map the first logical
channel and the second logical channel to all of the carriers
respectively after a preset time interval.
[0116] In 470, the terminal device sends second indication
information to the network device.
[0117] Optionally, the second indication information is used to
indicate that the terminal device has mapped the first logical
channel to all carriers, or the second indication information may
further indicate that the terminal device has mapped the second
logical channel to all carriers.
[0118] In the embodiments of the present disclosure, by receiving
the indication information sent by the network device, the terminal
device stops the duplication transmission of the data of one or
more radio bearers, and maps the logical channel to all carriers of
the plurality of carriers configured by the network device. Thus,
the logical channel can transmit data on the plurality of carriers,
thereby increasing the rate of data transmission.
[0119] The method embodiments of the present disclosure have been
described in detail in combination with FIGS. 2-4, and the
embodiments of the terminal device and the embodiments of the
network device according to the embodiments of the present
