Abstract
A method and apparatus for supporting XR services is provided. The method of a terminal includes receiving from a base station a Radio Resource Control (RRC) message, wherein the RRC message comprises a set of Packet Data Convergence Protocol (PDCP) parameters for a Data Radio Bearer (DRB), establishing a Data Radio Bearer (DRB) based on the set of PDCP parameters, starting a discard timer for a Service Data Unit (SDU) of the DRB and discarding one or more SDUs. In case that the discard timer expires, the terminal performs a first discard operation. In case that successful delivery of the SDU is confirmed by the PDCP status report, the terminal performs a second discard operation.
