Abstract: There is provided a method for transmitting data by a wireless device configured to support WAN communication and V2X communication, the method comprising scheduling a first data transmission to be performed in an N-th subframe, wherein the first transmission uses the WAN communication; scheduling a second data transmission to be performed in an (N−1)-th subframe, wherein the second transmission uses the V2X communication, wherein the (N−1)-th subframe for the second transmission is offset from the N-th subframe by a DFN (Direct Frame Number) offset; determining which one of the first transmission or the second transmission to be dropped, based on a priority between the WAN and V2X communications, wherein the determining is further based on comparison between a length of a last symbol in the (N−1)-th subframe for the second transmission with a length of the DFN offset.

Abstract: A method of receiving a synchronization signal for device-to-device (D2D) communication by a user equipment (UE) in a wireless communication system is provided. A synchronization signal is received from a base station (BS) to acquire synchronization. Information on capability of the UE related with a synchronization mode is transmitted to the BS. Information on the synchronization mode indicating a first synchronization mode or a second synchronization mode is received from the BS. A reference synchronization of transmitting a D2D signal is determined based on the synchronization mode. When the information on the synchronization mode indicates the second synchronization mode, a synchronization signal is received from a device except for the BS to acquire synchronization for D2D communication.

Abstract: Provided is a method for performing measurement by a user equipment (UE). The method may include receiving, by the UE, configuration information on a measurement gap. The UE may be configured with a dual connectivity (DC) to an evolved universal terrestrial radio access (E-UTRA) cell and a new radio access technology (NR) cell. The configuration information on the measurement gap may include a measurement gap length (MGL). The MGL may include one of 3 ms, 4 ms and 6 ms. The method may include determining a total number of slots to be interrupted during the MGL, and performing the measurement during the MGL. The total number of slots to be interrupted may be determined based on a subcarrier spacing (SCS) of the NR cell and the MGL
