Abstract: Provided are a method for operating a terminal in a wireless communication system, and a terminal using the method. The method is characterized in that a cell re-selection is performed during an RRC connection re-establishment process, and if a second cell selected through the cell re-selection does not provide D2D configuration, D2D operation is performed using D2D configuration obtained in a first cell, which is a cell that existed prior to the initiation of the RRC connection re-establishment process.

Abstract: During path switching between sidelink (SL) and uplink (UL) for vehicle-to-everything (V2X) message transmission, a path switching layer of a user equipment (UE), which may be located right above a packet data convergence protocol (PDCP) layer of the UE, stores a vehicle-to-everything (V2X) message, which is not transmitted yet on an old path, in a transmission buffer. And then, the path switching layer of the UE re-submits the V2X message stored in the transmission buffer to a lower layer of a new path.

Abstract: Provided are a method for a terminal receiving a service continuity indicator in a wireless communication system, and a device supporting same. A terminal may transmit a single-cell point-to-multipoint (SCPTM) service list to a serving cell and receive a service continuity indicator from the serving cell. The service continuity indicator may comprise first service information indicating an SCPTM service, among the SCPTM service list, that may be provided to the terminal by a target cell through SCPTM transmission.

Abstract: A method and apparatus for performing a device-to-device (D2D) operation in a wireless communication system is provided. A user equipment (UE) receives a D2D mode criterion from a network, and performs the D2D operation based on a D2D mode indicated by the D2D mode criterion. The D2D mode criterion may indicate various information, and may be either a D2D mode 1 or a D2D mode 2.

Abstract: A method and apparatus for configuring a device-to-device (D2D) discovery specific logical channel group (LCG) in a wireless communication system is provided. A user equipment (UE) calculates a buffer status for D2D discovery announcement, configures a specific LCG identifier (ID) to transmit the D2D discovery announcement, constructs a proximity based services (ProSe) buffer status report (BSR) based on the calculated buffer status and the configured LCG ID, and transmits the constructed ProSe BSR to an evolved NodeB (eNB).
