Abstract: A method and apparatus for determining to be a relay UE in a wireless communication system. A user equipment (UE) receives reference signal received power (RSRP) based criteria from a network, and determines to be a relay UE when a specific condition corresponding to the RSRP based criteria is met. The UE may further receive a hysteresis value from the network. When a measured RSRP of the UE plus the hysteresis value is below the RSRP threshold, the UE may determine to be a relay UE.

Abstract: The present invention relates to a method for transmitting a sidelink signal by a user equipment (UE) in a wireless communication system. The method comprises receiving, from a network, a threshold value for a transmission of the sidelink signal; receiving, from the network, an indicator indicating at least one of a specific UE category and a specific service type allowed to transmit the sidelink signal regardless of the threshold value; if a category of the UE is not the specific UE category and the UE is not operating with the specific service type, measuring quality of a serving cell of the UE; and if the quality of the serving cell is less than the threshold value, transmitting the sidelink signal to a target UE, wherein, if the category of the UE is the specific UE category or the UE is operating with the specific service type, the sidelink signal is transmitted to the target UE regardless of the threshold value

Abstract: Provided are a method of reselecting a cell by a terminal in a wireless communication system and a device supporting the same. A terminal may measure a cell on the basis of a priority, may calculate a ranking of the cell, using a cell measurement result, and may reselect a cell having the highest ranking. Otherwise, the terminal may measure a cell and evaluate a cell reselection criterion on the basis of a priority, may calculate a CE level with respect to a cell satisfying the cell reselection criterion evaluation, using a cell measurement result, and may reselect a cell having the lowest CE level. The terminal may be a terminal operating in a coverage extension mode and the coverage extension mode enables the cell measurement to be performed for a longer time than a normal mode.

Abstract: In an inter-master eNB (MeNB) handover procedure without secondary eNB (SeNB) change, a user equipment (UE) receives a SeNB kept indicator indicating that a SeNB has been kept successfully from a source MeNB. Upon receiving the SeNB kept indicator, the UE determines that the SeNB has been kept successfully in the inter-MeNB handover without SeNB change, and skips the random access procedure to the SeNB.

Abstract: Provides are a method for performing, by a terminal in a WLAN interworking operation, handover in a wireless communication system and an apparatus supporting the same. The terminal may be instructed to perform handover from a source cell to a target cell, but may receive a handover command including a WLAN interworking configuration indication to indicate that the terminal maintains or releases a WLAN interworking configuration for a WLAN being accessed by the terminal. The terminal may attempt to perform the handover to the target cell in the state in which the terminal has maintained the WLAN interworking configuration if the WLAN interworking configuration indication indicates that the terminal maintains the WLAN interworking configuration.

Abstract: A method and apparatus for indicating a logged multimedia broadcast multicast service (MBMS) measurement availability in a wireless communication system is provided. A user equipment (UE) determines whether to inform a serving cell that the UE has logged MBMS measurement results to be reported based on a first condition and a second condition, and when both the first condition and the second condition are met, the UE informs the serving cell that the UE has the logged MBMS measurement results. The first condition corresponds to that the UE has the logged MBMS measurement results to be reported. The second condition includes at least one MBMS minimization of drive tests (MDT) related condition.
