Abstract
Provided in the present invention are user equipment and a method thereof, and a base station and a method thereof. The method in user equipment comprises: receiving, from a base station, a MAC control element (MAC CE) for deactivating a packet data convergence protocol (PDCP) duplication; and deactivating the PDCP duplication based on the received MAC CE.
Claims5
-10. (canceled)
User equipment comprising:
- receiving circuitry configured to receive a Medium Access Control Control Element (MAC CE) used to indicate that one or more radio link control (RLC) entities associated to a data radio bearer (DRB) are activated or deactivated for packet data convergence protocol (PDCP) duplication;
- and
- processing circuitry configured to indicate, in a case that the MAC CE indicates that the one or more RLC entities are activated for PDCP duplication, to upper layers the activation of PDCP duplication for the indicated one or more RLC entities of the DRB, wherein
- an identity of the DRB is included in the MAC CE.

A method performed by user equipment comprising:
- receiving a Medium Access Control Control Element (MAC CE) used to indicate that one or more radio link control (RLC) entities associated to a data radio bearer (DRB) are activated or deactivated for packet data convergence protocol (PDCP) duplication;
- and
- indicating, in a case that the MAC CE indicates that the one or more RLC entities are activated for PDCP duplication, to upper layers the activation of PDCP duplication for the indicated one or more RLC entities of the DRB, wherein
- an identity of the DRB is included in the MAC CE.
1 more element
Abase station comprising:
- processing circuitry configured to generate a Medium Access Control Control Element (MAC CE) used to indicate that one or more radio link control (RLC) entities associated to a data radio bearer (DRB) are activated or deactivated for packet data convergence protocol (PDCP) duplication;
- and
- transmitting circuitry configured to transmit the MAC CE to user equipment, wherein
- in a case that the MAC CE indicates that the one or more RLC entities are activated for PDCP duplication, the MAC CE causes the user equipment to indicate, to upper layers of the user equipment, the activation of PDCP duplication for the indicated one or more RLC entities of the DRB, and
- an identity of the DRB is included in the MAC CE.

A method performed by a base station comprising:
- generating a Medium Access Control Control Element (MAC CE) used to indicate that one or more radio link control (RLC) entities associated to a data radio bearer (DRB) are activated or deactivated for packet data convergence protocol (PDCP) duplication;
- and
- transmitting the MAC CE to user equipment, wherein
- in a case that the MAC CE indicates that the one or more RLC entities are activated for PDCP duplication, the MAC CE causes the user equipment to indicate, to upper layers of the user equipment, the activation of PDCP duplication for the indicated one or more RLC entities of the DRB, and
- an identity of the DRB is included in the MAC CE.
