Claim 10:
11. A user equipment (UE) in a wireless communication system, the UE comprising:
a transceiver; and
a controller configured to:
receive, from a base station (BS) via the transceiver, a first message configuring a Packet Data Convergence Protocol (PDCP) duplication for a radio bearer,
configure a primary Radio Link Control (RLC) entity and one or more secondary RLC entities for the PDCP duplication, and
