1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a first base station, a radio resource control (RRC) message including at least one packet data convergence protocol (PDCP) configuration information including PDCP duplication information;
receiving, from the first base station, a first medium access control (MAC) control element (CE) activating the PDCP duplication for a data radio bearer (DRB) configured with the PDCP duplication;
generating a first PDCP protocol data unit (PDU) and submitting the first PDCP PDU to a primary radio link control (RLC) entity;
generating a second PDCP PDU and submitting the second PDCP PDU to a secondary RLC entity, wherein the second PDCP PDU is a duplicate of the first PDCP PDU; and
transmitting the first PDCP PDU to the first base station and the second PDCP PDU to a second base station.
