    Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. More particularly, the disclosure relates to a method performed by a control plane (CP) of a base station in a wireless communication system. The method comprises transmitting, to a user plane (UP) of the base station, a first message comprising information on a packet data convergence protocol (PDCP) for each data radio bearer (DRB). As a response to the first message, the method further comprises receiving, from the UP of the base station, a second message. The information on the PDCP for each DRB comprises at least one PDCP version.
