Abstract: A method and apparatus for small data transmission in RRC inactive state in MR-DC is provided. A MN, in a DC for a wireless device, transmits, to the wireless device, a paging message including an indication related to an EDT procedure for the SN. A MN receives, from the wireless device, an AS-RAI related to the EDT procedure for SN. A MN decides whether to continue the EDT procedure to the wireless device for the DL data or to transit the wireless device to the RRC-CONNECTED state based on the received AS-RAI.

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 support of CU-DU split in MT-EDT procedure in a wireless communication system is provided. A Central Unit (CU) of a Radio Access Network (RAN node) receives, from a Distributed Unit (DU) of the RAN node, second information related to a transport block used for the wireless device. The CU decides a Radio Resource Control (RRC) state for transmitting the downlink (DL) data to the wireless device based on the first information related to the DL data and the second information related to the transport block.

Abstract: One disclosure of the present specification provides a method for supporting redundant protocol data unit (PDU) sessions. The method may be performed by a unified data management (UDM) node and comprise: receiving, from a first session management function (SMF) node, a first message including a first redundancy sequence number (RSN) which is allocated by the first SMF node for managing a first PDU session and an identifier of the first PDU session; transmitting, to a second SMF node for managing a second PDU session, a second message including the first RSN and a PDU session pair ID, which is identical to the identifier of the first PDU session; and receiving, from the second SMF node, a third message including a second RSN which is allocated by the second SMF node and an identifier of the second PDU session. The second PDU session may be duplication of the first PDU session.

Abstract: Provided are a method of managing UE context and a device supporting the method. According to one embodiment of the present invention, a method for managing UE context in a wireless communication system includes: receiving a UE context request message including a radio resource control (RRC) establishment cause from a second BS, wherein the first BS and the second BS are located in a same radio access network (RAN)-based notification area (RNA); and when the RRC establishment cause is related to RNA update, transmitting a UE context response message to the second BS, wherein the UE context response message piggybacks a RRC message requesting a UE to move to a RRC inactive state.
