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.

Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method for a base station of a wireless communication system is provided. The method comprises the steps of receiving, from a user equipment in an inactive mode (INACTIVE) to a distributed unit (DU) of the base station, a radio resource control (RRC) message including uplink data, transmitting from, the DU to a centralized unit-control plane (CU-CP) of the base station, a first message including at least one of indicator information related to transmission of the uplink data and identifier information of a data radio bearer (DRB) corresponding to the uplink data, and transmitting the uplink data to a user plane function (UPF), on the basis of the first message.
