1. A method of a terminal in a wireless communication system, the method comprising:
receiving, from a base station, a radio resource control (RRC) message configuring a data radio bearer (DRB), the RRC message configuring the DRB including service data association protocol (SDAP) configuration information for the DRB, a DRB identity for the DRB, and packet data convergence protocol (PDCP) configuration information for the DRB; and
configuring an SDAP entity associated with at least one PDCP entity based on the received RRC message configuring the DRB,
wherein the SDAP configuration information for the DRB included in the RRC message configuring the DRB includes an indicator indicating whether an SDAP header is present or absent for the DRB.
