Claim 11:
12. A method, performed by a terminal, for controlling packet duplication in a wireless communication system, the method comprising:
receiving a duplication activation/deactivation information associated with a plurality of secondary Radio Link Control (RLC) entities for a Data Radio Bearer (DRB) as a format of Medium Access Control (MAC) Control Element (CE); and
in case that the duplication activation/deactivation information 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, duplicating a first Packet Data Convergence Protocol (PDCP) packet for the at least one secondary RLC entity, and deliver the duplicated first PDCP packet to the at least one secondary RLC entity,
wherein the duplication activation/deactivation information 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 the plurality of the RLC fields for the DRB indicate activation or deactivation status of PDCP duplication for the plurality of the secondary RLC entities.
