For convenience of description, some contents related to the embodiments of the present invention are explained below:

once, PDCP duplication (PDCP duplication) function introduction

In NR, a data copy function is introduced in the PDCP layer in order to improve reliability of data transmission. The network side device may configure a data copy function for a certain RB of the UE and the PDCP layer performs the function. If the data replication function of a RB is activated, the PDCP layer corresponding to the RB replicates data to be delivered to a lower layer, and sends the original data and the replicated data through two different transmission paths, such as two different RLC (Radio Link Control) entities, where the different RLC entities correspond to different logical channels.

In an embodiment, the network side device may start (i.e., activate) or stop (i.e., deactivate) the PDCP copy function through a MAC CE (Medium Access Control element) signaling instruction.

In another embodiment, when configuring the data copy function of a certain RB, the network side device may configure whether the function is turned on immediately after configuration, so that MAC CE signaling is not required to indicate activation or deactivation of the PDCP data copy function.

Bearer type of PDCP copy function

The 5G (5th-Generation, fifth Generation) mobile communication system employs a DC architecture. In the DC architecture, two Cell groups, MCG (Master Cell Group) and SCG (Secondary Cell Group), are included. The MCG corresponds to an MN (Master Node) of the network side device, and the SCG corresponds to an SN (secondary Node) of the network side device. The network side device may configure a plurality of SRBs (Signaling Radio bearers) for the UE, including SRBs 1 and SRBs 2 configured on the MCG and SRBs 3 configured on the SCG.

The bearer types of the PDCP copy function may include at least the following two bearers:

split bearer (Split bearer): for the same separated bearer, its corresponding PDCP entity is in 1 cell group, and its corresponding 2 RLC entities and 2 MACs are in different cell groups.

Exemplarily, as shown in fig. 2a, illustrated with a split bearer a. The separation bearer a is configured with a transmission path a1 and a transmission path a2, wherein the transmission path a1 corresponds to a PDCP entity in the MCG, an RLC entity 1 in the MCG and a MAC entity in the MCG; the transmission path a2 corresponds to the PDCP entity in the MCG, the RLC entity 1 in the SCG, and the MAC entity in the SCG.

Copy bearer (Duplicate bearer): for the same duplicate bearer, 1 PDCP entity, 2 RLC entities and 1 MAC entity are in 1 cell group.

Exemplarily, as shown in fig. 2b, the duplicate bearer a is illustrated. The duplicate bearer a is configured with a transmission path a1 and a transmission path a2, wherein the transmission path a1 corresponds to a PDCP entity in the MCG, an RLC entity 1 in the MCG, and a MAC entity in the MCG; the transmission path a2 corresponds to the PDCP entity in the MCG, the RLC entity 2 in the MCG, and the MAC entity in the MCG.

In addition, for the duplicate bearer, data from different RLC entities may be sent through different cells, and a Cell for transmitting data may be an SCell (Secondary Cell) or a PCell (Primary Cell).

It should be noted that, in the embodiment of the present invention, if the RLC entities corresponding to bearers are distributed in different cell groups, the bearers may be referred to as separate bearers; if the RLC entities corresponding to the bearers are distributed in the same cell, the bearers may be referred to as duplicate bearers, but other names may be made by the standard organization, and the present invention is not affected by the names.

In the embodiment of the present invention, a target RB corresponding to a terminal is configured with a data copy function, and the target RB is configured with N transmission paths, where N is an integer greater than 2. However, for a scenario in which the network side device configures N transmission paths for the RB, the determination of an available transmission path of the RB and the determination of the transmission BWP of the transmission path of the RB, there is no solution at present.

Therefore, the present invention provides a bearer control method, which may determine an available transmission path of the target RB and/or determine a transmission bandwidth portion BWP associated with the transmission path of the target RB, so that when a terminal performs data transmission using the transmission path of the target RB and/or performs data transmission on the BWP associated with the transmission path of the target RB, a success rate of data transmission may be increased, and thus reliability of data transmission may be increased.

It should be noted that the bearer control method according to the embodiment of the present invention may be applied to a DC (dual connectivity) and/or CA (Carrier Aggregation) architecture. That is, the present invention can study the PDCP data copy of more than 2 copies using at least one of DC (Dual Connectivity) and CA (Carrier Aggregation).

The following describes a bearer control method according to an embodiment of the present invention.

Referring to fig. 3, fig. 3 is a flowchart of a bearer control method according to an embodiment of the present invention. The bearer control method of this embodiment may be applied to a terminal. As shown in fig. 3, the bearer control method of this embodiment may include the following steps:

step 301, receiving an RB configuration message sent by a network side device.

Wherein the RB configuration message may include at least one of:

BWP restriction information.

In one embodiment, optionally, the BWP restriction information is used to configure an association relationship between a transmission path and BWP; wherein the BWP in the association is: BWP available or BWP unavailable.

In this embodiment of the present invention, optionally, the transmission path may be identified by at least one of: cell group identification and/or logical channel identification. The transmission path corresponds to a unique RLC entity and different RLC entities correspond to different logical channels, and thus, it can be understood that the transmission path corresponds to a unique logical channel.

Therefore, in another embodiment, optionally, the BWP restriction information is used to configure an association relationship between a logical channel and BWP; wherein the BWP in the association is: BWP available or BWP unavailable.

In a specific implementation, if the BWP in the association relationship is an available BWP, the UE may transmit data from the transmission path associated with the BWP on the BWP, that is, the UE may transmit data transmitted via the transmission path associated with the BWP on the BWP; if the BWP in the association is an unavailable BWP, the UE may not transmit the data from the transmission path associated with the BWP on the BWP, that is, for each transmission path in the association, the data transmitted from a certain transmission path may not be transmitted on the BWP associated with the transmission path.

It should be noted that, in the embodiment of the present invention, different transmission paths of the same RB may correspond to different BWPs of the same serving cell (e.g., SCell). For this scenario, the network-side device may configure different BWPs for multiple transmission paths of the same RB corresponding to the serving cell. In this way, the UE may transmit data of different transmission paths on different BWPs, and due to different risks of data transmission on different BWPs, compared with transmitting data from different transmission paths on the same BWP, the UE may reduce the risk of data transmission failure, thereby improving reliability of data transmission.

Exemplarily, it is assumed that the first RB includes a transmission path 1 and a transmission path 2, and the first SCell is configured with BWP1 and BWP2, wherein in the BWP restriction information, the transmission path 1 is associated with BWP1, the transmission path 2 is associated with BWP2, and BWP1 and BWP2 are available BWPs. The UE may transmit data from the transmission path 1 on BWP1 and data from the transmission path 2 on BWP2, so that reliability of data transmission may be improved.

Therefore, in the above association relationship, the associated BWP may be different for transmission paths (or logical channels) corresponding to different cells; for a transmission path (or logical channel) corresponding to the same cell, there may be at least two transmission paths associated with different BWPs.

Optionally, BWP may be identified by at least one of: cell group identification; a cell identity; BWP identification.

In addition, it should be understood that, when the initial state of the data copy function of the target RB is the active state, the number of the initial available transmission paths of the target RB may be greater than or equal to 2, that is, the RB configuration message may include an initial available transmission path set.

When the data copy function of the target RB is deactivated, the number of available transmission paths of the target RB may be greater than or equal to 1. When the number is greater than 1, the RB configuration message may include an available transmission path set of the target RB when the data copy function of the target RB is deactivated.

In the embodiment of the present invention, the target RB is configured with N transmission paths. In practical application, the network side device may send a first configuration message to the terminal, where the first configuration message is used to configure N transmission paths associated with the target RB.

In a specific implementation, the first configuration message may include: identification of the target RB (e.g., SRB identification or DRB identification) and configuration information of the N RLC entities. Thereby establishing the association relation between the N transmission paths corresponding to the N RLC entities and the target RB.

The N RLC entities may belong to the same cell group or different cell groups.

It should be noted that, in practical application, the first configuration message and the RB configuration message may be the same configuration message or different configuration messages, which may be determined specifically according to practical needs, and this is not limited in the embodiment of the present invention.

Step 302, determining an available transmission path of the target RB according to the RB configuration message, and/or determining a transmission bandwidth portion BWP associated with the transmission path of the target RB.

In a specific implementation, the UE may determine the UE according to the content included in the RB configuration message, which is specifically described as follows:

in case that the RP configuration message includes BWP restriction information, the UE may determine BWP associated with the transmission path of the target RB according to the RB configuration message.

Optionally, the association relationship includes a first transmission path and a first BWP associated with each other;

the determining a transmission bandwidth part BWP associated with the transmission path of the target RB includes:

when the first BWP is available, allocating an uplink grant received from the first BWP to the first transmission path by a Media Access Control (MAC) entity corresponding to the first transmission path; or the like, or, alternatively,

and under the condition that the first BWP is unavailable, the MAC entity corresponding to the first transmission path allocates the uplink grant received from the first BWP to other transmission paths except the first transmission path.

And under the condition that the first BWP is available, allocating the uplink grant received from the first BWP to the first transmission path by the MAC entity corresponding to the first transmission path, so that the data transmitted from the first transmission path can be transmitted on the first BWP.

And under the condition that the first BWP is unavailable, the MAC entity corresponding to the first transmission path allocates the uplink grant received from the first BWP to other transmission paths except the first transmission path. In this way, data transmitted from the first transmission path may not be transmitted on the first BWP.

It can be seen that, by the above method, a transmission BWP of data transmitted via a certain transmission path can be defined, and thus data transmission reliability can be improved. It should be noted that the above method may be equally applied to a scenario where two transmission paths are configured by the target RB.

The RB configuration message comprises: when the initial state of the data copying function of the target RB is an activated state, the initial available transmission path of the target RB; and/or when the data replication function of the target RB is deactivated and the available transmission path of the target RB is available, the UE may determine the available transmission path of the target RB according to an RB configuration message.

Specifically, when the UE may set the initial state of the data copy function of the target RB to an active state, the UE may set an initial available transmission path of the target RB; and/or when the data copying function of the target RB is deactivated, determining the available transmission path of the target RB as the available transmission path of the target RB.

Therefore, when data are transmitted through the available transmission path of the target RB, the reliability of data transmission can be improved; in addition, compared with the transmission through N transmission paths, the resource utilization rate can be improved.

The bearer control method of this embodiment may not only improve the reliability of determining the available transmission path of the target RB and/or the BWP associated with the transmission path of the target RB; further, when the terminal performs data transmission by using the transmission path of the target RB and/or performs data transmission on the BWP associated with the transmission path of the target RB, the success rate of data transmission can be increased, thereby increasing the reliability of data transmission. Therefore, the invention can improve the data transmission performance.

In this embodiment of the present invention, when the target RB is a split bearer, optionally, the RB configuration message further includes at least one of the following:

k separate bearer thresholds, wherein K is a positive integer;

and separating the association relation between the bearing threshold and the available transmission path.

In this way, the UE may further determine the available transmission path of the target RB according to the K separate bearer thresholds and/or the association relationship between the separate bearer thresholds and the available transmission path, so as to further improve the data transmission performance.

After step 302, after determining an available transmission path of the target RB and/or determining a transmission bandwidth part BWP associated with the transmission path of the target RB according to the RB configuration message, the method further includes:

receiving an indication message sent by the network side device, where the indication message is used to indicate to activate or deactivate a data copy function of the target RB, and/or is used to indicate to activate or deactivate a transmission path of the target RB;

and acquiring the states of the N transmission paths according to the indication message.

The state of the transmission path may be used to characterize whether the transmission path is available or activated. Of course, it should be understood that a transmission path may be used to transmit data if the transmission path is activated.

It should be noted that, in the embodiment of the present invention, when the indication message is used to indicate to activate or deactivate the transmission path of the target RB, the indication message may indicate to activate or deactivate the entire transmission path of the target RB, or indicate to activate or deactivate a part of the transmission path of the target RB, which may be specifically determined according to actual needs, and this is not limited in the embodiment of the present invention.

In a specific implementation, optionally, the indication message is:

radio resource control, RRC, signaling, the RRC signaling being used to instruct activation or deactivation of a data copy function of the target RB and/or to instruct activation or deactivation of a transmission path of the target RB; or the like, or, alternatively,

a first media access control layer control element (MAC CE) signaling, wherein the first MAC CE signaling is used for indicating to activate or deactivate a data copying function of the target RB; or the like, or, alternatively,

second MAC CE signaling for indicating activation or deactivation of a transmission path of the target RB.

Optionally, the second MAC CE signaling includes: a cell group identity and/or a logical channel identity; or, the second MAC CE signaling includes: a first field for identifying the target RB and a second field for indicating the state of a transmission path with sequence number i in N transmission paths of the target RB;

wherein i is an integer greater than or equal to 0 and less than or equal to N.

Optionally, when the target RB is a split bearer, the second MAC CE further includes a split bearer indication field, configured to indicate whether the target RB deactivates a data replication function and rolls back to a split bearer mode.

In practical applications, the signaling format of the first MAC CE may be as shown in fig. 4. In fig. 4, the first MAC CE signaling may include a Di field, which may be used to indicate whether a data copy function of an RB with sequence number i (e.g., DRB) is activated.

Illustratively, if the value of the Di field is "1", it indicates that the data copy function of the RB with the serial number i is activated; and if the Di field takes a value of 0, the data copying function of the RB with the sequence number of i is deactivated.

It should be noted that fig. 4 is only an example, and the embodiment of the present invention does not limit the format of the first MAC CE signaling.

The second MAC CE signaling may include a MAC CE subheader and a MAC CE body. The format of the MAC CE subheader may refer to fig. 5a, and the MAC CE body may refer to fig. 5b, fig. 5c, and fig. 5 d. It should be noted that the second MAC CE signaling corresponding to fig. 5b is the second MAC CE signaling of the scenario one, and the second MAC CE signaling corresponding to fig. 5c and fig. 5d is the second MAC CE signaling of the scenario two.

As shown in fig. 5a, the MAC CE subheader may include an R field, an F field, an LCID field, and an L field.

Wherein the R field is a reserved bit. As shown in fig. 5a, the R field may be set at the first bit of Oct (byte) 1 as the R field.

The F field is used to indicate the length of the L field in bytes. Illustratively, the F field value is "0", which indicates that the L field length is one byte, and the F field value is "1", which indicates that the L field length is two bytes. As shown in fig. 5a, the F field may be set at the second bit of Oct 1.

The LCID field is used to indicate a type of the MAC CE signaling corresponding to the subheader, for example, the data copy function activates and deactivates the MAC CE signaling, where a value of the LCID field may multiplex an LCID value used to indicate the type of the first MAC CE signaling in the first MAC CE signaling, or may be a newly introduced LCID value, which may be specifically determined according to actual needs. As shown in fig. 5a, the LCID field may be set at the last 6 bytes of Oct 1.

The L field is used to indicate the length of the MAC CE that is lengthened. As shown in fig. 5a, the L field may be provided at Oct2 and Oct 3.

As shown in fig. 5b, the body of the MAC CE includes a Dn domain, a Serving Cell Group ID (Serving Cell Group identity) domain, and an LCID domain.

The Dn field is used to identify whether the RB with sequence number n is in the data copy active mode or the split bearer mode, and may correspond to the split bearer indication field. For example, if the value of the Dn field is "0", it may indicate that the RB is in the data copy function activation mode; if the value of the Dn field is "1", it may indicate that the RB is in the split bearer mode.

The Dn domains may be arranged in ascending order according to DRB (Data Radio Bearer) identities of Radio bearers configured with a Data copy function.

It should be noted that the RB identified by the Dn domain needs to satisfy that it has a corresponding RLC entity belonging to the cell group where the MAC entity receiving the MAC CE signaling is located. In this embodiment of the present invention, the second MAC CE signaling may be used to indicate to activate or deactivate the transmission path of the target RB, which indicates that the target RB satisfies: and the RLC entity corresponding to the target RB comprises an RCL entity which belongs to the same cell group with the MAC entity receiving the second MAC CE signaling.

The Serving Cell Group ID field may be used to identify a Cell Group identity, and the LCID field may be used to identify a logical channel identity. It should be understood that the Serving Cell Group ID field and/or LCID field may uniquely identify a transmission path.

In a specific implementation, when the target RB is in the data copy activation mode, if the second MAC CE signaling carries a domain identifying a transmission path associated with the target RB, the transmission path identified by the domain in the target RB may be activated, otherwise, the transmission path is deactivated by default. When the target RB is in the split bearer mode (i.e., the data duplication function deactivation mode), if the second MAC CE signaling carries a domain identifying a transmission path associated with the radio bearer, it indicates that the transmission path identified by the domain in the target RB is an available transmission path, otherwise, the transmission path is an unavailable transmission path.

As shown in fig. 5c and 5D, the body of the MAC CE includes a D/Sm field, a DRB IDm field, an Lmi field, and an R field.

Wherein, the R field is a reserved bit.

The D/Sm field may be used to identify whether the RB with sequence number m is in data copy active mode or split bearer mode. For example, the D/Sm field takes a value of "0", indicating that RB with sequence number m is in the data copy active mode; the D/Sm field takes the value "1", indicating that RB with sequence number m is in split bearer mode.

The DRB IDm field may be used to identify an RB identity configured with a data copy function, and may correspond to the first field described above.

Lmi, it is indicated whether or not the transmission path with sequence number i associated with the radio bearer for identifying DRB IDm is activated, and may correspond to the second domain described above. For example, Lmi takes a value of "1" to indicate that the transmission path with sequence number i is activated, and Lmi takes a value of "0" to indicate that the transmission path with sequence number i is deactivated.

Wherein, the numbering rule of the transmission path associated with the RB is as follows: for transmission paths in different cell groups, numbering the transmission paths in ascending order of cell group identification; for transmission paths in the same cell group, the transmission paths may be numbered in the ascending order of their corresponding LCIDs.

It should be noted that, in practical applications, the format of the second MAC CE signaling may be represented by fig. 5a and fig. 5b, or represented by fig. 5a and fig. 5c, or represented by fig. 5a and fig. 5 d. It should be understood, however, that the formats in fig. 5a, 5b, 5c and 5d are only examples, and the embodiment of the present invention does not limit the specific representation form of the second MAC CE signaling.

In practical application, the UE may determine the state of the transmission path of the target RB by combining the RB configuration message and the indication message, and further determine the processing behavior of the UE according to the state of the transmission path of the target RB, which is specifically described as follows:

implementation mode one

In this embodiment, the data copy function of the target RB is in an active state, and the N transmission paths include i active state transmission paths. Optionally, after obtaining the states of the N transmission paths according to the indication message, the method further includes:

if the target data to be transmitted by the target RB is detected, performing at least one of the following operations:

a first operation: the PDCP entity of the target RB sends first indication information to MAC entities corresponding to the i active transmission paths respectively, the number of the first indication information received by each MAC entity is equal to that of the active transmission paths corresponding to the MAC entity, and the first indication information is used for indicating the PDCP data capacity;

a second operation: the PDCP entity of the target RB sends the target data to Radio Link Control (RLC) entities respectively corresponding to the i active transmission paths;

a third operation: the MAC entities respectively corresponding to the i active transmission paths determine BWPs (virtual machines/servers) which are respectively associated with the i active transmission paths and are used for transmitting the target data according to the BWP restriction information;

wherein i is an integer greater than or equal to 2.

For the first operation, the PDCP entity of the target RB sends i pieces of first indication information, configured to indicate PDCP data capacities to MAC entities corresponding to the i active transmission paths, respectively, where the number of the first indication information received by each MAC entity is equal to the number of the active transmission paths corresponding to the MAC entity. Therefore, each MAC entity can apply for corresponding network resources for transmitting the received target data, and the success rate of target data transmission can be improved.

and adding the activated transmission path as an available transmission path of the target RB.

In this way, the UE can perform data transmission by using the active transmission path in the present embodiment, so that the reliability of data transmission can be improved.

It should be noted that, various optional implementations described in the embodiments of the present invention may be implemented in combination with each other or implemented separately, and the embodiments of the present invention are not limited thereto.

For convenience of understanding, the control method of the bearer according to the embodiment of the present invention may include the following steps:

step 1: the network side equipment issues 'radio bearer configuration information of multiple transmission paths' to the UE.

It should be understood that the "radio bearer configuration information of multiple transmission paths" in this step may correspond to the "RB configuration message" in the above-described method embodiment.

The configuration information may comprise one or more of the following in combination:

a radio bearer identification, such as SRB ID, or DRB ID;

configuration information of N (N > -3) RLC entities associated with the radio bearer, wherein the N RLC entities may belong to the same cell group or different cell groups;

an indication of whether a data copy function is configured;

an initial state of the data copy function, e.g., activated, deactivated;

available transmission paths (sets) when the data copy function is disabled;

carrier or BWP (bandwidth part) restriction information;

one or more split bearer thresholds;

separating the association relationship of the bearer threshold value and the available transmission path (set);

wherein, the "transmission path" is identified by one or more of the following information combinations:

cell group identification, such as serving cell ID;

When the initial state of the data copy function of the radio bearer is active, the configuration information may further include:

an initial set of available transmission paths for a data replication function;

wherein, the number M of the initial available transmission paths of the data copying function is less than or equal to N;

the "carrier or BWP (bandwidth part) restriction information" is used to configure an association relationship between the logical channel and the carrier or BWP, where the association relationship may be:

data from a certain logical channel may be transmitted on a certain carrier (set) or BWP (set);

data from a certain logical channel may not be transmitted on a certain carrier (set) or BWP (set);

wherein, the BWP is identified by one or more of the following combinations of information: cell group identification; a serving cell identity; a bandwidth part identification;

the network node that issues the "radio bearer configuration information of multiple transmission paths" may be any one of the following: a serving base station under a single connection architecture; a master node under a multi-connection architecture; and (5) auxiliary nodes under the multi-connection architecture.

Step 2: and the UE receives a data copying function activation and deactivation indication signaling from the network side equipment. It should be understood that the "activation/deactivation indication of the data copy function" in this step may be equivalent to the "indication message" in the above-described method embodiment.

Wherein, the type of the indication signaling is any one of the following types:

RRC signaling;

legacy activation/deactivation MAC CE signaling;

newly introduced duty activation/deactivation MAC CE signaling.

It should be noted that the "Legacy activation/deactivation MAC CE signaling" may be equivalent to the first MAC CE signaling in the method embodiment; the above-mentioned "newly introduced duty/deactivation MAC CE signaling" may be equivalent to the second MAC CE signaling in the above-mentioned method embodiment.

The UE processes the indication signaling, and indicates a sending PDCP entity corresponding to the radio bearer to acquire one or more of the following combination information: m deactivated transmission paths; n active transmission paths, wherein m + N is less than or equal to N.

Case 1: if the number of transmission paths currently in an activated state is less than two after the UE executes the data copy function activation/deactivation instruction received from the network side device, the sending PDCP entity of the UE disables the data copy function of the radio bearer, and the subsequent data transmission is transmitted via an available transmission path (set) when the data copy function configured by the network side device is disabled.

Case 2: if the UE has the transmission path deactivated after executing the data copy function activation deactivation instruction received from the network side device, the sending PDCP entity indicates the RLC entity corresponding to the deactivated transmission path to discard all the copy data received from the upper layer.

Case 3: if the UE has a transmission path activated after executing the data copy function activation/deactivation instruction received from the network side device, the UE adds the activated transmission path or paths to the available transmission path of the radio bearer.

And step 3: when the data copy function of a certain radio bearer is in an active state and the number of available transmission paths in the active state is a (a ≧ 2), if the data of the radio bearer needs to be sent, the processing behavior of the UE includes one or more of the following combinations:

the sending PDCP entity corresponding to the radio bearer respectively indicates the PDCP data capacity to the MAC entity of the cell group to which the RLC corresponding to the a transmission path in the activated state belongs;

when a PDCP entity is sent to deliver a data packet to a lower layer, firstly copying a parts of the data packet, and then respectively delivering the data packet to RLC entities corresponding to a transmission paths in an activated state;

the MAC entity transmits data from a transmission path in an active state through an available carrier or BWP configured by a network side device; or not via an unavailable carrier or BWP configured by the network side device;

and 4, step 4: additionally, when the PDCP entity receives a notification of successful transmission of a PDCP data PDU from the currently active transmission path, the sending PDCP entity instructs the RLC entities corresponding to the remaining (a-1) active transmission paths to discard the duplicated PDCP data PDU;

wherein, the notification indicating the successful transmission of a certain PDCP data PDU may come from the following entities:

any RLC entity corresponding to the transmission path in the activated state currently;

any MAC entity corresponding to the transmission path in the activated state;

the RLC entity processes the discarded PDCP data PDU indication sent by the PDCP as follows:

for radio bearer of AM (Acknowledged Mode), if RLC has delivered PDCP data PDU indicated by PDCP to (over) underlay, RLC ignores PDCP indication information;

for a radio bearer of UM (Unacknowledged Mode), the RLC entity discards PDCP data PDUs indicated by PDCP.

By adopting the method of the invention, the network side equipment can configure a plurality of transmission paths and a data replication function for the radio bearer of the UE, and the UE can control the uplink data to be transmitted only by a specific BWP in the process of passing through a specific number of transmission paths based on the RB configuration message configured by the network side, thereby improving the reliability of data transmission. In addition, when receiving the indication message of the network side device, the UE can determine a subsequent available transmission path based on the indication message, and perform data transmission based on the determined available transmission path, which can improve the reliability of data transmission and improve the resource utilization rate.
