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: Provided are a method in which a source base station (BS) transmits a Quality of Service (QoS) flow-to-data radio bearer (DRB) mapping rule to a target BS in a wireless communication system, and a device supporting the same. The method may include: receiving, from a user equipment (UE), a measurement result of a target cell; determining the handover of the UE to the target BS on the basis of the measurement result; and transmitting, to the target BS, a handover request message including a QoS flow-to-DRB mapping rule of the source BS.

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 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 apparatus for controlling mobile early data transmission (EDT) procedure in a wireless communication system is provided. A first core network node, in a wireless communication, receives, from a second core network node, a message for a downlink Data including a size of the downlink data. The first core network node determines whether to initiate an early data transmission (EDT) procedure for the downlink data based on the size of the downlink data. The first core network node transmits, to a radio access network (RAN) node, a paging message including information related to the EDT procedure for the downlink data based on the decision to initiate the EDT procedure for a wireless device.
