Abstract: The present disclosure relates to a mobility enhancement in wireless communications. According to an embodiment of the present disclosure, a user equipment (UE) may perform an optimized mobility based on validity information informing which cells/mobility commands are valid for the optimized mobility. Therefore, the UE may identify one or more cells among all neighbor cells in a cell list to which optimized mobility is possible without receiving an additional signaling for the cell list, and prevent mobility failure caused by a mobility to a wrong cell.

Abstract: A method and apparatus for a source cell release indication for dual stack mobility in a wireless communication system is provided. A wireless device, which initiates a mobility from a source node to a target node, keeps communicating with the source node, and receives, from the target node, an indication. Upon receiving the indication, the wireless device stops communicating with the source node.

Abstract: A method and apparatus for supporting a DAPS handover procedure in a wireless communication system is provided. A target BS receives, from a source BS, a first message for a dual active protocol stack (DAPS) handover of a wireless device. A target BS transmits, to the source BS, a second message to inform that the DAPS handover is accepted. A target BS receives, from the wireless device, a third message including an information that the wireless device does not perform the DAPS handover. A target BS transmits, to the source BS, a fourth message including the information received from the wireless device.
