1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station, first information configuring a packet duplication for a radio bearer, second information on a first logical channel mapped to a first serving cell, and third information on a second logical channel mapped to a second serving cell, wherein a first radio link control (RLC) entity for the radio bearer corresponds to the first logical channel, a second RLC entity for the radio bearer corresponds to the second logical channel, and the first information is set to true;
transmitting, to the base station, a data packet from the first RLC entity and a duplicated data packet from the second RLC entity based on the first information, wherein the data packet is transmitted on the first serving cell based on the second information and the duplicated data packet is transmitted on the second serving cell based on the third information;
receiving, from the base station, a medium access control (MAC) control element (CE) indicating a deactivation of the packet duplication; and
discarding all duplicated data packets in the second RLC entity for the radio bearer, based on the MAC CE.
