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 switching of multicast and broadcast service between multicast and unicast in a wireless communication system is described. A CU-CP establishes a connection with a wireless device for a Multicast and/or Broadcast Service (MBS). A CU-CP receives, from the CU-UP, a first message including a retransmission information on data transmission related to the MBS. A CU-CP determines whether to perform a switch of the first transmission to a second transmission for the MBS based on the retransmission information.

Abstract: A method and apparatus for supporting an early data transmission (EDT) in a radio resource control (RRC) inactive state is provided. The current gNB receives a resume request message including uplink (UL) data from the wireless device, and transmits a logical channel identifier (LCID) for the UL data to the last serving gNB. The last serving gNB transmits UL forwarding user plane (UP) transport network layer (TNL) information to the current gNB based on mapping between the LCID for the UL data and data radio bearer (DRB) ID or protocol data unit (PDU) session ID in a UE context stored in the last serving gNB. The current gNB forwards the UL data to a core network via the last serving gNB based on the UL forwarding UP TNL information.
