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.

Abstract: A method and an apparatus for multicast transmission with separation of CP and UP in a wireless communication system are provided. A CU-UP of a RAN node receives, from a CU-CP of the RAN node, a first message for a MBS, wherein the first message includes (1) an ID of the MBS, and (2) a C-TEID for the MBS. A CU-UP establishes a bearer for the MBS based on the ID of the MBS. A CU-UP receives, from a core network, data for the MBS via a tunnel indicated by the C-TEID. A CU-UP transmit, to the DU, the received data via the established bearer.

Abstract: A method and apparatus for controlling radio resource of a redundant route for a dual-connecting Integrated Access and Backhaul (IAB) node in a wireless communication system will be provided. The CU of the IAB-donor is connected with a dual-connecting IAB-node via a master cell group (MCG) IAB-node. The CU of the IAB-donor initiates an establishment of a connection with the dual-connecting IAB-node via a secondary cell group (SCG) IAB-node. The CU of the IAB-donor transmits, to the SCG IAB-node, a first information which informs not allocating radio resource for a bearer. The CU of the IAB-donor determines to use the connection with the dual-connecting IAB-node via the SCG IAB-node. The CU of the IAB-donor transmits, to the SCG IAB-node, a second information to request allocating the radio resource for the bearer.
