Abstract

Provided in the present disclosure are user equipment and a method thereof, and a base station and a method thereof. The method performed by the user equipment includes: receiving a radio resource control (RRC) message from a base station, wherein the RRC message includes information related to an activation configuration of packet data convergence protocol (PDCP) duplication of a radio bearer and/or associated radio link control (RLC) entities; and performing the activation configuration of the PDCP duplication and/or the associated RLC entities on the basis of the information. Thus, the communication efficiency and reliability of a wireless communication system can be improved.

Claims (13)

1. User equipment (UE), comprising:

receiving circuitry configured to receive a radio resource control (RRC) message; and

processing circuitry configured to determine whether packet data convergence protocol (PDCP) duplication of a data radio bearer (DRB) is activated or deactivated based on at least whether the RRC message includes an indication indicating that at least one associated radio link control (RLC) entity other than a primary RLC entity is activated for the PDCP duplication; wherein

the processing circuitry determines that the PDCP duplication of the DRB is activated in a case that the indication included in the RRC message indicates that at least one associated RLC entity other than the primary RLC entity is activated for the PDCP duplication; and

the processing circuitry determines that the PDCP duplication of the DRB is deactivated in a case that the RRC message does not include the indication which indicates that at least one associated RLC entity other than the primary RLC entity is activated for the PDCP duplication.

2. The UE according to claim 1 , wherein the indication is only configured for the DRB.

3. A base station, comprising:

generation circuitry configured to generate a radio resource control (RRC); and

transmission circuitry configured to transmit the RRC message to user equipment (UE), wherein the UE determines whether packet data convergence protocol (PDCP) duplication of a data radio bearer (DRB) is activated or deactivated based on at least whether the RRC message includes an indication indicating that at least one associated radio link control (RLC) entity other than a primary RLC entity is activated for the PDCP duplication, wherein the UE determines that the PDCP duplication of the DRB is activated in a case that the indication included in the RRC message indicates that at least one associated RLC entity other than the primary RLC entity is activated for the PDCP duplication, and determines that the PDCP duplication of the DRB is deactivated in a case that the RRC message does not include the indication which indicates that at least one associated RLC entity other than the primary RLC entity is activated for the PDCP duplication.

4. The base station according to claim 3 , wherein the indication is only configured for the DRB.

5. A method performed by a base station, comprising:

generating a radio resource control (RRC); and

transmitting the RRC message to user equipment (UE), wherein the UE determines whether packet data convergence protocol (PDCP) duplication of a data radio bearer (DRB) is activated or deactivated based on at least whether the RRC message includes an indication indicating that at least one associated radio link control (RLC) entity other than a primary RLC entity is activated for the PDCP duplication, wherein the UE determines that the PDCP duplication of the DRB is activated in a case that the indication included in the RRC message indicates that at least one associated RLC entity other than the primary RLC entity is activated for the PDCP duplication, and determines that the PDCP duplication of the DRB is deactivated in a case that the RRC message does not include the indication which indicates that at least one associated RLC entity other than the primary RLC entity is activated for the PDCP duplication.
