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: comprises: receiving a switching MAC CE from a base station; and activating and/or deactivating an RLC entity and/or a logical channel associated with a bearer that supports the PDCP duplication based on the switching MAC CE.
Claims7
-10. (canceled)
User equipment comprising:
- a processor;
- and
- a memory in electronic communication with the processor,
- instructions stored in the memory being executable to determine that one or more radio link control (RLC) entities associated to a data radio bearer (DRB) are deactivated for packet data convergence protocol (PDCP) duplication,
- the instructions being executable to indicate to the one or more RLC entities deactivated for the PDCP duplication to discard all duplicated PDCP data protocol data units (PDUs).
2 more elements
A base station comprising:
- a processor;
- and
- a memory in electronic communication with the processor,
- instructions stored in the memory being executable to generate a Medium Access Control Control Element (MAC CE) based on which one or more radio link control (RLC) entities associated to a data radio bearer (DRB) are determined as being deactivated for packet data convergence protocol (PDCP) duplication,
- the instructions being executable to transmit the MAC CE to User equipment,
- the MAC CE causing the User equipment to indicate to the one or more RLC entities deactivated for PDCP duplication to discard all duplicated PDCP data protocol data units (PDUs).
3 more elements
A method performed by User equipment, the method comprising:
- determining that one or more radio link control (RLC) entities associated to a data radio bearer (DRB) are deactivated for packet data convergence protocol (PDCP) duplication;
- and
- indicating to the one or more RLC entities deactivated for the PDCP duplication to discard all duplicated PDCP data protocol data units (PDUs).
A method performed by a base station comprising:
- generating a Medium Access Control Control Element (MAC CE) based on which one or more radio link control (RLC) entities associated to a data radio bearer (DRB) are determined as being deactivated for packet data convergence protocol (PDCP) duplication;
- and
- transmitting the MAC CE to User equipment, the MAC CE causing the User equipment to indicate to the one or more RLC entities deactivated for PDCP duplication to discard all duplicated PDCP data protocol data units (PDUs).
