Abstract
The present disclosure relates to a 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE). Embodiments herein disclose methods for handling lossless operations for a MBS in a wireless communication network (). The method includes receiving, by a network entity (), a PDCP status report from a UE (). The PDCP status report includes missing PDU. The missing PDU is detected during at least one of a MBS bearer type change, a MBS data transfer and a handover procedure involving a MBS bearer. Further, the method includes determining, by the network entity (), a PDCP PDU for retransmission of the missing PDU. Further, the method includes retransmitting, by the network entity (), the determined PDCP PDU to the UE () over a PTP path. The method can be used to is enable reliability with efficient retransmission during a PTM-PTP switching, a handover and a normal operation for a NR MBS. Based on the proposed method, a UE MBS service reception performance is enhanced.
