METHOD AND APPARATUS FOR REPORTING PDCP CONTROL MESSAGE FOR DISCARDED PDCP SDUS IN THE IDENTIFIERS IN MOBILE WIRELESS COMMUNICATION SYSTEM
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 the DRB based on the set of PDCP parameters, starting a discard timer for a Service Data Unit (SDU) of the DRB, discarding one or more SDUs of the DRB upon expiry of the discard timer and transmitting to the base station a PDCP discard report in case that the set of PDCP parameters for the DRB comprises a parameter related to the PDCP discard report. The PDCP discard report comprises a first field related to COUNT of a first discarded SDU.
