Assignee: SHARP KABUSHIKI KAISHA
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A user equipment comprising:
a processor; and
a memory in electronic communication with the processor,
instructions stored in the memory being executable by the processor to receive a Medium Access Control (MAC) Control Element (CE) carrying an identity of a data radio bearer (DRB), the MAC CE further carrying a plurality of fields for respective radio link control (RLC) entities associated with the DRB, each of the plurality of fields indicating whether a corresponding one of the RLC entities is activated or deactivated for packet data convergence protocol (PDCP) duplication, the plurality of fields being arranged in ascending or descending order of logical channel identities of the RLC entities,
the instructions stored in the memory further being executable by the processor to determine, based on the MAC CE, that one or more of the RLC entities associated with the DRB are deactivated for the PDCP duplication, and
the instructions further being executable by the processor to indicate to the one or more of the RLC entities deactivated for the PDCP duplication to discard all duplicated PDCP data protocol data units (PDUs).
