Abstract: The present invention relates to a device-to device (D2D) operation method performed by a terminal in a wireless communication system. The method comprises: separately receiving, from a serving cell, measurement bandwidth information about a frequency not included in information indicative of a measurement object for the purpose of supporting the mobility of the terminal; measuring the frequency not included in the measurement object for the purpose of supporting the mobility on the basis of the measurement bandwidth information; selecting a cell on the frequency; and performing discovery announcement on the cell.

Abstract: Provided are a method for performing interworking of a terminal in a wireless communications system, and a terminal using said method. The method comprises the steps of: receiving a threshold value with respect to a single parameter in which a plurality of parameters for determining whether a traffic control is performed between a first network and a second network are combined; measuring the value of the single parameter with respect to the second network; and determining whether traffic control has been performed by comparing the result of the measurement of the single parameter to the threshold value.

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: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for changing a connection by a user equipment (UE) connected with a relay UE through a device to device (D2D) link in a wireless communication system, the method comprising: receiving information on a threshold value through a broadcast signaling; measuring a quality of a channel from a cell; establishing a radio resource control (RRC) connection with the cell when the measured quality is higher than the threshold value; and releasing the D2D link with the relay.

Abstract: A method of selecting a relay user equipment (UE) performed by a remote UE in wireless communication system, and a UE using the method are provided. The method includes determining whether a measurement of a current relay UE is smaller than a threshold and selecting a candidate relay UE satisfying a specific condition as a relay UE when the measurement of the current relay UE is smaller than the threshold. Here, the candidate relay UE is selected as a relay UE only when a measurement of the candidate relay UE is greater than a minimum hysteresis value (minHyst) based on the threshold.

Abstract: A method and apparatus for performing multimedia broadcast multicast service (MBMS) minimization of drive test (MDT) in a wireless communication system is provided. A user equipment (UE) receives a MBMS-MDT timer configuration from a network. A MBMS-MDT timer is newly defined for the MBMS-MDT. The UE starts the MBMS-MDT timer based on the received MBMS-MDT timer configuration when a specific condition, which relates to degradation of quality of MBMS, is met, and while the MBMS-MDT timer is running, the UE performs the MBMS-MDT.

Abstract: A method and apparatus for performing traffic steering from a 3rd generation partnership project (3GPP) access network to a wireless local area network (WLAN) in a wireless communication system is provided. A user equipment (UE) receives radio access network access network (RAN) assistance information for evaluating traffic steering from the 3GPP access network to the WLAN, and attempts to acquire attributes related to the RAN assistance information from a specific WLAN. If at least one of the attributes is not acquired from the specific WLAN, the UE evaluates traffic steering from the 3GPP access network to the WLAN excluding the specific WLAN. The RAN assistance information includes a WLAN signal power threshold and a WLAN load threshold.

Abstract: A method and apparatus for performing a random access procedure in a wireless communication system is provided. In one embodiment, a user equipment (UE) determines a required amount of repetitions for uplink transmissions during a random access procedure, and performs repetitions for uplink transmissions based on the determined required amount of repetitions for uplink transmissions.

Abstract: A method for changing a coverage enhancement (CE) mode at a user equipment (UE) in a wireless communication system in a wireless communication system is disclosed. The method includes steps of determining a CE mode level to be changed, transmitting a CE mode change request message to a network based on the determined CE mode level, and receiving a CE mode change message from the network via a physical downlink control channel. Especially, when the determined CE mode level is greater than a current CE mode level, a random access preamble associated with the determined CE mode level is transmitted to the network as the CE mode change request message.
