Abstract: A method and apparatus for switching between unicast and multicast by considering degraded user experience in a wireless communication system is described. A CU of a RAN node receives, from the DU, a first switching message including status of the MBS for each of the first wireless device and the second wireless device. A CU of a RAN node determines to switch the first transmission to a third transmission only for the first wireless device for the MBS, based on the received status of the MBS.

Abstract: A method and apparatus for managing measurement results for early measurement in a wireless communication system is provided. A wireless device receives, from a network, measurement configuration for early measurement, wherein the measurement configuration includes 1) a first frequency group for a first Radio Access Technology (RAT), and 2) a second frequency group for a second RAT. A wireless device transmits a measurement report including the measurements results of only one of the first frequency group and the second frequency group. A wireless device discards the stored measurement results of the other one of the first frequency group and the second frequency group which are not transmitted to the network.

Abstract: Proposed is a method for performing a sidelink operation in a wireless communication system, the method being performed by a terminal. The method comprises: selecting a preferred resource pool from among a plurality of resource pools, wherein the preferred resource pool is one of a first resource pool including a physical sidelink feedback channel (PSFCH) resource and a second resource pool without the PSFCH resource; and, on the basis of a re-selection condition, performing the sidelink operation on the first resource pool or the second resource pool.

Abstract: The present invention relates to a method of performing a handover procedure by a user equipment (UE) in a wireless communication system. Especially, the method includes the steps of initializing state variables for at least one radio bearer (RB) based on receiving a handover command from a source network; performing the handover procedure to a target network while maintaining the connection with the source network; based on detecting a handover failure to the target network, reverting back the state variables for the at respectively, and applying the first network configuration least one RB to the state variables used in the source network; and reporting information related to the handover failure to the source network.

Abstract: A method and apparatus for validating time alignment for preconfigured uplink resource in a wireless communication system is provided. A wireless device receives, from a network at a first time point, configuration of uplink transmission which is to be performed at a second time point. A wireless device configures a window which starts at a third time point between the first time point and the second time point. A wireless device checks whether time alignment (TA) is valid or not inside of the window.
