Abstract: An embodiment of the present invention provides a method for receiving a physical sidelink control channel (PSCCH) and a physical sidelink shared channel (PSSCH) by a terminal in a wireless communication system. The method for receiving a PSCCH and a PSSCH comprises the steps of: receiving a PSCCH comprising information, which indicates a time interval between a PSCCH and a PSSCH indicated by means of the PSCCH, and information which indicates whether the PSSCH is retransmission; and receiving the PSSCH in a resource determined by means of the information indicating the time interval and the information indicating whether the PSSCH is retransmission, wherein, on the basis of whether the PSSCH is retransmission, the information indicating the time interval is determined to be used as a positive value or a negative value when the resource is determined.

Abstract: The present invention relates to a method for electricity measurement by a vehicle-to-vehicle (V2V) device for V2V communications in a wireless communication system and to a device therefor. In particular, the present invention includes the steps of: receiving at least one synchronization signal for V2V through a physical sidelink broadcast channel (PSBCH); and measuring received electricity from said at least one synchronization signal if the ID of said at least one synchronization signal is linked to a demodulation reference signal (DMRS) sequence having, applied thereto, an orthogonal cover code (OCC) having one fixed value, wherein the measurement is performed by means of averaging for each ID of said at least one synchronization signal.
