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

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