Abstract: A method and apparatus for handling QoE report in a secondary node in a wireless communication system is provided. An SN transmits, to a UE, a configuration for Quality of Experience (QoE) measurement. The QoE measurement is initiated by an Operations, Administration and Maintenance (OAM) and/or a master node (MN). An SN receives, from the UE, a QoE report based on the configuration. An SN determines whether to forward the QoE report to (i) a Trace Collection Entity (TCE) and/or a Measurement Collection Entity (MCE) and/or (ii) the MN, based on which entity among the OAM and/or the MN initiates the QoE measurement. An SN forwards the QoE report based on the determination.

Abstract: A method and apparatus for stopping multicast and broadcast service in a wireless communication system is provided. A CU-UP of a RAN node receives, from a CU-CP of the RAN node, a first message to initiate a MLD) and/or IGMP Leave procedure. A CU-UP of a RAN node performs the MLD and/or IGMP Leave procedure for the MB service indicated by the identity for the MB service along with an MB-UPF based on the Transmission Stop Indication. A CU-UP of a RAN node transmits, to the CU-CP of the RAN node, a second message informing that the MLD and/or IGMP Leave procedure is completed.
