1. A terminal for controlling packet duplication in a wireless communication system, the terminal comprising:
a transceiver; and
at least one processor coupled to the transceiver and configured to:
receive, from a base station, a duplication activation/deactivation medium access control (MAC) control element (CE) associated with a plurality of secondary radio link control (RLC) entities for a data radio bearer (DRB); and
in case that the duplication activation/deactivation MAC CE associated with the plurality of the secondary RLC entities for the DRB indicates duplication activation of at least one secondary RLC entity from the plurality of the secondary RLC entities for the DRB, duplicate a first packet data convergence protocol (PDCP) packet, and deliver the first PDCP packet to a primary RLC entity and the duplicated first PDCP packet to the at least one secondary RLC entity,
wherein the duplication activation/deactivation MAC CE associated with the plurality of the secondary RLC entities for the DRB includes an identity of the DRB and a plurality of RLC fields for the DRB, and
wherein an RLC field of the plurality of the RLC fields for the DRB corresponds to a secondary RLC entity of the plurality of the secondary RLC entities and indicates activation or deactivation status of PDCP duplication for the secondary RLC entity.
