Claim 15:
16. A base station (BS) in a wireless communication system, the BS comprising:
a transceiver; and
a controller configured to:
transmit, to a user equipment (UE) via the transceiver, a first message configuring a Packet Data Convergence Protocol (PDCP) duplication for a radio bearer, wherein the first message is associated with a primary Radio Link Control (RLC) entity and one or more secondary RLC entities being configured for the PDCP duplication in the UE,
transmit, to the UE via the transceiver, a second message related to a deactivation of the PDCP duplication, and
in case that the PDCP duplication is deactivated for the radio bearer and a split secondary RLC entity is configured among the one or more secondary RLC entities, receive, from the UE via the transceiver, a PDCP Protocol Data Unit (PDU) which is transmitted based on either the primary RLC entity or the split secondary RLC entity.
