Abstract: For continuous data transmission during a handover procedure, Make-Before-Break handover may be introduced, which maintains source evolved NodeB (eNB) connection after reception of radio resource control (RRC) message for handover. In order to reduce ambiguity of Make-Before-Break handover, the present invention provides receiving a handover command from a network, after receiving the handover command from the network, keeping exchanging data with a source cell, stopping exchanging data with the source cell when a condition is met, and after stopping exchanging data with the source cell, starting exchanging data with a target cell.

Abstract: Provided are a method of measuring by using a terminal in a wireless communication system, and a device supporting same. The terminal may: measure on the basis of a reference signal; receive a reference signal flag from a network; and derive a new measurement result on the basis on the received reference signal flag. The reference signal flag issues instructions as to whether a reference signal is sent from a target subframe, and the target subframe is a subframe used to derive the new measurement result.

Abstract: Provided is a method for denying transmission by a terminal in a wireless communication system. A terminal may receive an effective period and a threshold value, count the number of autonomous denial subframes during the effective period, and deny transmission in a current subframe if the counted number of the autonomous denial subframes is less than the threshold value.

Abstract: A method and apparatus for performing multimedia broadcast multicast service (MBMS) minimization of drive test (MDT) in a wireless communication system is provided. Upon receiving a MBMS-MDT configuration from a network, a user equipment (UE) selects a subset of multicast broadcast single frequency network (MBSFN) areas among multiple MBSFN areas providing interested MBMS services, and performs MBMS-MDT only for the selected subset of MBSFN areas. The subset of MBSFN areas may be selected based on priorities of the multiple MBSFN areas.

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.
