Abstract: A method and apparatus for 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 join a multicast group for a MB service. A CU-UP of a RAN node performs the MLD and/or IGMP Join procedure for the MB service indicated by the identity for the MB service along with an MB-UPF based on the LL MC address. A CU-UP of a RAN node transmits, to the CU-CP of the RAN node, a second message including a Join Complete Indication informing that joining the multicast group for the MB service is completed.

Abstract: A method and apparatus for supporting a link congestion detection in a in an integrated access and backhaul (IAB) network is provided. An IAB-donor-central unit (CU) performs downlink (DL) transmission, receives information about a problem on a backhaul (BH)-radio link control (RLC) channel between a first IAB-node and a second IAB-node, and stop/reduces the DL transmission to the second IAB-node via the BH-RLC channel between the first IAB-node and the second IAB-node based on the information. The IAB-donor-CU may select a path towards the second IAB-node other than the BH-RLC channel between the first IAB-node and the second IAB-node, and perform DL transmission towards the second IAB-node via the selected path.

Abstract: A method and apparatus for enhancing a gNB distributed unit (DU) change procedure to manage radio resource allocation in a wireless communication system is provided. A gNB central unit (gNB-CU), which performs an inter-gNB-DU mobility, receives, from a source gNB-DU, information on a radio link control (RLC) protocol data unit (PDU), which is to be transmitted to a user equipment (UE) at the source gNB-DU but undelivered, and transmits, to a target gNB-DU, the information on the RLC PDU. The gNB CU transmits, to the target gNB-DU, a PDCP PDU based on the information on the RLC PDU, after receiving the information on the RLC PDU.

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: The present disclosure relates to a conflict resolution in wireless communications. According to an embodiment of the present disclosure, a method performed by a central unit (CU) of a first integrated access and backhaul (IAB) donor node serving a wireless device with a second IAB donor node in a dual connectivity (DC) in a wireless communication system comprises: receiving, from a CU of the second IAB donor node, information for a first address of the wireless device allocated by the second IAB donor node; based on that the first address conflicts with an address of one or more IAB nodes served by the first IAB donor node, determining a second address different from the address of the one or more IAB nodes; and transmitting, to the CU of the second IAB node, information for the second address.

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.

Abstract: A method and apparatus for network support indication for user equipment (UE) provided protocol data unit (PDU) session pair information is provided. A wireless device (e.g., UE) transmits, to a network, a first protocol data unit (PDU) session establishment request including (i) PDU session pair information informing PDU sessions paired for redundant transmission, and (ii) first capability information informing that the wireless device supports inclusion of the PDU session pair information in the first PDU session establishment request. The wireless device receives, from the network, second capability information indicating whether the network is aware of the inclusion of the PDU session pair information in the first PDU session establishment request. The wireless device determines whether to include the PDU session pair information in a second PDU session establishment request based on whether the second capability information.
