Referring to fig. 3, fig. 3 provides a configuration method of a DRB, which is implemented under a network architecture as shown in fig. 1a or fig. 1b, where the type of the MAC CE in this embodiment is the first type as shown in fig. 2 a. The method may be performed by a terminal, as shown in fig. 3, and includes the following steps:

step S301, the terminal receives an RRC message sent by the base station, where the RRC message may include: one or any combination of DRB identification, PDCP duplicate activation information of DRB, activation information of logical channel LCH, activation information of RLC leg, configuration information of LCH.

Wherein, the PDCP duty activation information of the DRB is indication information indicating whether the PDCP duty is activated.

The activation information of the LCH or RLC leg refers to indication information of whether the LCH is activated for transmitting data.

The configuration information of the LCH refers to one or more LCHs configured by the DRB, and indicates LCH ids corresponding to primary path1 and primary path2, and may also include configuration parameters of the LCH. Wherein primary path1 refers to primary path in MCG and primary path2 refers to primary path in SCG. Upon DC deactivation, PDUs of the PDCP are routed and may be transmitted in primary path1 and/or primary path 2.

The RRC message may include configuration information of one or more DRBs.

If the initial status of the PDCP duty of the DRB is active, the RRC message indicates that the PDCP duty is active. The RRC message also indicates the activated RLC leg/entry/LCH.

The implementation method of step S301 may specifically include:

and the terminal performs configuration corresponding to the DRB, and performs duplicate operation on the PDCP layer and sends the PDCP PDU to the corresponding RLC entity if the PDCP duplicate activation is indicated in the RRC message. If the PDCP duplication is not activated as indicated in the RRC message, the terminal does not perform duplication operation in the PDCP layer, and if the terminal is configured as a CA, performs CA operation, that is, maps the corresponding LCH to the corresponding cell group.

The RRC message may include, but is not limited to, RRC Reconfiguration, RRC Reestablishment, RRC Resume, RRC Setup messages.

Step S302, the terminal receives the MAC CE sent by the base station, and the MAC CE comprises: a status indication of a DRB;

the status indication of the DRB may include: activation or deactivation.

Step S303, the terminal configures the DRB according to the status indication of the DRB and the current status of the DRB.

The MAC CE may include PDCP duplicates of multiple DRBs, for example, as shown in fig. 2a, the MAC CE may include status indications of 8 DRBs, where the status indication of each DRB may be represented by 1 bit, and in an alternative scheme, for example, a value D0 being 1 may represent that the PDCP duplicates of D0 are in an active state, and a value D0 being 0 may represent that the PDCP duplicates of D0 are in a deactivated state.

The following is a practical example to illustrate a specific implementation manner of the method of the embodiment of the present application. Assume that the MAC CE is: 11000110, according to the corresponding relationship of DRB of MAC CE as shown in FIG. 2a, D1, D2, D6, D7 are activated, D0, D3, D4, D5 are deactivated. The PDCP duplicate of D1, D2, D6 and D7 is activated at the current state, and the terminal does not carry out activation or deactivation operation; if the PDCP duplicate states of D1, D2, D6 and D7 are deactivated, the PDCP duplicate states of D1, D2, D6 and D7 are changed to be activated, and all RLC leg/entry corresponding to D1, D2, D6 and D7 are activated. Taking D1 as an example, if D1 has 3 RLC legs/entries, the terminal activates all 3 RLC legs/entries, the terminal copies 3 PDCP PDUs to obtain 3 PDCP PDUs, and sends the 3 PDCP PDUs to the 3 activated RLC legs/entries.

For the PDCP duplicate current states of D0, D3, D4 and D5 being active, under the network architecture shown in FIG. 1a, the RLC leg 1/entry 1 corresponding to the primary path1 of D0, D3, D4 and D5 is kept active, and the rest RLC legs/entries (i.e. RLC leg/entries except RLC leg 1/entry 1) of D0, D3, D4 and D5 are changed to be deactivated; as under the network architecture shown in FIG. 1b, RLC leg 1/entry 1 corresponding to primary path1 of D0, D3, D4 and D5 and RLC leg 2/entry 2 corresponding to primary path2 are reserved as active, and the remaining RLC legs/entries (i.e., RLC leg/entries other than RLC leg 1/entry 1 and RLC leg 2/entry 3) of D0, D3, D4 and D5 are deactivated instead.

For the PDCP duplicate current states of D0, D3, D4 and D5 being deactivated, if the RLC leg 1/entry 1 currently activated by D0, D3, D4 and D5 is non-primary path (), the RLC leg 1/entry 1 of D0, D3, D4 and D5 is switched to primary path1 under the network architecture shown in FIG. 1 a; under the network architecture shown in FIG. 1b, currently activated RLC leg 1/entry 1 and RLC leg 2/entry 2 are non-primary path, RLC leg 1/entry 1 of D0, D3, D4 and D5 is switched to primary path1, and RLC leg 2/entry 2 of D0, D3, D4 and D5 is switched to primary path 2.

Optionally, after step S303, the method may further include: under the network architecture shown in fig. 1a, a terminal sends PDCP PDUs to a primary path1 corresponding to the primary path1 according to the data volume; under the network architecture shown in FIG. 1b, the terminal sends PDCP PDUs to RLC leg 1/entry 1 and RLC leg 2/entry 2 corresponding to primary path1 and primary path2 or only to RLC leg 1/entry 1 corresponding to primary path1 according to the data volume.

As shown in fig. 3, the base station may flexibly implement the operation of DRB PDCP duration activation and deactivation and the operation of DRB RLC leg activation and deactivation through the MAC CE, and signaling overhead may also be saved through the MAC CE.

Referring to fig. 4, fig. 4 provides a configuration method of a DRB, which is implemented under a network architecture as shown in fig. 1a or fig. 1b, where the type of the MAC CE in this embodiment is the second type as shown in fig. 2 b. The method may be performed by a terminal, as shown in fig. 4, and includes the following steps:

step S401, the terminal receives an RRC message sent by the base station, where the RRC message may include: one or any combination of DRB identification, PDCP duplicate activation information of DRB, activation information of logical channel LCH, activation information of RLC leg, configuration information of LCH.

The implementation method of step S401 may specifically include: and the terminal performs configuration corresponding to the DRB, and performs duplicate operation on the PDCP layer and sends the PDCP PDU to the corresponding RLC entity if the PDCP duplicate activation is indicated in the RRC message. If the PDCP duplication is not activated as indicated in the RRC message, the terminal does not perform duplication operation in the PDCP layer, and if the terminal is configured as a DC, the terminal performs DC operation, that is, PDCP PDUs can be transmitted in the MCG and the SCG.

Step S402, the terminal receives the MAC CE sent by the base station, and the MAC CE comprises: status indication of DRB and/or RLC leg status indication;

in an alternative scheme, as shown in fig. 2b, the RLC leg status indication may be a first bitmap, and the first bitmap may be 4 bits, specifically as shown in fig. 2 b. One sequence of the 4 bits is: a primary cell MCG primary RLC leg, a secondary cell SCG primary RLC leg, an MCG RLC legs and SCG RLC legs, namely RLC _0 represents the MCG primary RLC leg, RLC _1 represents the SCG primary RLC leg, RLC _2 represents the MCG RLC leg and RLC _3 represents the SCG RLC leg; the other sequence of the 4 bits is: MCG primary RLC leg, MCG RLC legs, SCG primary RLC leg and SCG RLC legs; that is, RLC _0 represents MCG primary RLC leg, RLC _1 represents MCG RLC leg, RLC _2 represents SCG primary RLC leg, and RLC _3 represents SCG RLC leg.

The status indication of the DRB may include: activation or deactivation.

In an alternative, the MAC CE may further include: a second bitmap, which may be an identity of the DRB, indicating said identity of the DRB explicitly or implicitly, e.g. the second bitmap is indicated by the DRB id in order of small to large or large to small.

Step S403, the terminal configures the DRB according to the status indication and the current status of the DRB.

The implementation method of step S403 may specifically include:

and if the MAC CE does not contain the DRB ID, for each DRB, activating or deactivating the corresponding RLC leg/entry according to the activation state indication of all the RLC legs/entries of the DRB in the MAC CE. For example, the MAC CE is 1101, RLC _0, RLC _1, and RLC _3 are set to active, and RLC _2 is set to inactive. And if the MAC CE contains the DRB ID, activating or deactivating the corresponding RLC leg/entry for the DRB corresponding to the ID according to the activation state indication of all RLC leg/entries of the DRB in the MAC CE. For example, if the MAC CE is 101101, RLC _0, RLC _1, and RLC _3 of D2 (DRB corresponding to D11) are set to be activated, and RLC _2 of D2 is set to be deactivated, where the DRB ID takes 2 bits as an example, and in practical applications, the DRB ID may include 4 bits or other number of bits.

In an alternative scheme, in the network architecture shown in fig. 1a, if only one (i.e. only) RLC leg of the first bitmap is activated (for example, the first bitmap is 1000), the terminal sets the PDCP duplicate of the DRB to be deactivated.

In the embodiment shown in fig. 4, the base station can flexibly implement the operation of activating and deactivating the DRB PDCP duration and the operation of activating and deactivating the RLC leg of the DRB through the MAC CE, and signaling overhead can be saved through the MAC CE.

In the embodiment shown in fig. 4, the method may further include:

if the MAC CE includes the PDCP duty information of the DRB as deactivation, under the network architecture shown in fig. 1a, if only one RLC leg/entry is activated (e.g., RLC leg 1/entry 1 is activated), the terminal configures the LCH corresponding to RLC1 leg1 as primary path 1.

Under the network architecture shown in fig. 1b, the PDCP duty information of the DRB is deactivated, and if both the MCG and the SCG have only one RLC leg/entry activated, the terminal configures an LCH corresponding to the only activated RLC leg 1/entry 1 in the MCG as primary path1, and configures an LCH corresponding to the only activated RLC leg 2/entry 2 in the SCG as primary path 2.

The technical scheme can realize the updating of primary path1 and primary path2 through the MAC CE.
