Abstract: A method and apparatus for switching between unicast and multicast by considering degraded user experience in a wireless communication system is described. A CU of a RAN node receives, from the DU, a first switching message including status of the MBS for each of the first wireless device and the second wireless device. A CU of a RAN node determines to switch the first transmission to a third transmission only for the first wireless device for the MBS, based on the received status of the MBS.

Abstract: The present disclosure relates to manual closed access group (CAG) selection in wireless communications. According to an embodiment of the present disclosure, a method performed by a central unit (CU) in a wireless communication system comprises: receiving, from a distribution unit (DU), information informing whether to allow a manual closed access group (CAG) selection on a CAG identifier (ID) not included in a list of allowed CAG IDs of a wireless device for each of public land mobile networks (PLMNs); receiving, from an access and mobility management function (AMF), a list of PLMNs supported by the AMF; determining CAG control information informing at least one PLMN for which a manual CAG selection on a CAG ID not included in the list of allowed CAG IDs of the wireless device is allowed, based on the list of PLMNs supported by the AMF and the information received from the DU; and transmitting, to the DU, the CAG control information.

Abstract: A method and apparatus for determining to switch between unicast and multicast in a wireless communication system is provided. A CU of a RAN node provides, via the DU, the MBS by using a first transmission to the wireless device. A CU of a RAN node receives, from the DU, measurement report for the MBS generated by the wireless device. A CU of a RAN node determines whether to switch the first transmission to a second transmission for the MBS based on the measurement report. A CU of a RAN node provides, via the DU, the MBS by using the second transmission to the wireless device.

Abstract: A method and apparatus for enhancing a handover procedure for supporting conditional handover in a wireless communication system. A source base station (e.g. source gNB/eNB) receives a message informing that a wireless device is handed over from the source base station to a target base station (e.g. target gNB/eNB). The target base station is one of candidate target base stations in the conditional handover procedure. After receiving the message, the source base station transmits a sequence number (SN) status transfer message to the target base station.

Abstract: A method and apparatus for lossless uplink data transmission of IAB network in a wireless communication system will be provided. A user plane (UP) of an integrated access and backhaul (IAB)-donor central unit (CU) in a wireless communication system receives, from a wireless device, uplink data through a source IAB-node. A UP of an IAB-donor CU receives, from the source IAB-node, at least one of a delivery status of the uplink data on the source IAB-node, wherein the wireless device handovers from the source IAB-node to a target IAB-node. A UP of an IAB-donor CU transmits, to a unit-control plane (CP) of the IAB-donor CU, a first message based on the at least one of the delivery status of the uplink data.

Abstract: Provided is a method for supporting E-UTRAN-NR dual connectivity (EN-DC) indicating dual connectivity between Long-Term Evolution (LTE), that is, Evolved UMTS Terrestrial Radio Access Network (E-UTRAN), and New Radio (NR) Access Technology (NR) in a wireless communication system. A first radio access network (RAN) node transmits an X2 configuration request message, including a first indication indicating that the first RAN node supports EN-DC, to a second RAN node, and receives an X2 configuration response message, including a second indication indicating that the second RAN node supports the EN-DC, from the second RAN node.
