摘要： The disclosure relates to a pre-5th generation (5G) or 5G communication system for supporting higher data rates beyond a 4th generation (4G) communication system such as long term evolution (LTE). A method performed by a network entity for handling a multicast and broadcast service (MBS) in a 5G communication network is provided that includes receiving a request for receiving at least one multicast service from a user equipment (UE), which includes at least one of a session join request or a service request, configuring the at least one multicast service based on the request, and sending the at least one multicast service to the UE over a radio resource control (RRC) reconfiguration message, which includes at least one of a point-to-multipoint (PTM) bearer configuration for a point-to-point (PTM) mode, a PTP bearer configuration for a PTP mode, or a split bearer configuration for a split bearer mode.

摘要： 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 (1000). The method includes receiving, by a network entity (200), a PDCP status report from a UE (100). 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 (200), a PDCP PDU for retransmission of the missing PDU. Further, the method includes retransmitting, by the network entity (200), the determined PDCP PDU to the UE (100) 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.

摘要： Embodiment herein provides a method for handling packet duplication and resumption of Radio Bearers (RBs) in a wireless communication system. The method includes receiving, by a base station, a Radio Resource Control (RRC) connection reestablishment request message from a User Equipment (UE). Further, the method includes sending, by the base station, a RRC connection reestablishment message on a default Signaling Radio Bearer (SRB) to the UE. The RRC connection reestablishment message is sent on the default SRB for allowing a re-establishment of Dedicated Radio Bearers (DRBs), a first SRB, and a second SRB without waiting for reception of a RRC reestablishment complete message from the UE. Further, the method includes receiving, by the base station, the RRC reestablishment complete message from the UE.

摘要： Method for reporting latency of packet transmission in a communication network. The method includes receiving by an entity an UL packet from a UE at a first time unit, wherein the UL packet includes a second time unit at which the packet is sent from the UE. Measuring by the entity a latency in transmission of the packet based on a time difference between the first time unit and the second time unit and performing by the entity at least one action based on the latency.Receiving by a UE a DL packet from an entity at a first time unit, wherein the DL packet comprises a second time unit at which the packet is transmitted from the entity. Measuring by the UE a time difference between the first time unit and the second time unit for the DL packet. Reporting by the UE a latency report to the entity.
