Abstract: An embodiment of the present invention relates to a method for transmitting a sidelink signal by a terminal in a wireless communication system, the method comprising the steps of: generating a sequence for transmitting a sidelink signal; mapping the sequence to a plurality of subcarriers around a sidelink direct current (DC) subcarrier; and transmitting a sequence for transmitting the mapped sidelink signal, wherein the location of the sidelink DC subcarrier has been inherited from a location of a DC subcarrier when the terminal transmits an uplink signal to a base station or a location of a DC subcarrier when the terminal receives a downlink signal from the base station. The first terminal is included in an autonomous vehicle.

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: An embodiment of the present invention relates to a method for a device-to-device (D2D) terminal transmitting a physical sidelink shared channel (PSSCH) in a wireless communication system. The PSSCH transmission method comprises the steps of: receiving a physical sidelink control channel (PSCCH) and a PSSCH transmitted in a resource region indicated by means of the PSCCH; if an energy measurement value with respect to the PSSCH is greater than a preset threshold, selecting a transmission resource excluding the resource region in which the PSSCH has been transmitted; and transmitting a D2D signal by means of the selected transmission resource, wherein the threshold has a value that varies in accordance with whether or not the PSSCH is retransmission or the redundancy version (RV) of the PSSCH.
