Abstract: Provided are a method for transmitting a relay signal for V2X communication in a wireless communication system and a device using the same. Specifically, a terminal receives allocation information of a first relay resource and a second relay resource for a communication group from a base station. A first terminal receives a data signal through a reception beam for the first relay resource from a second terminal. The first terminal transfers the data signal to a third terminal through a transmission beam for the first relay resource. Further, the first terminal transmits an ACK/NACK for the data signal to the second terminal through a transmission beam for the second relay resource. The reception beam for the first relay resource is symmetrical to the transmission beam for the second relay resource. The transmission beam for the first relay resource is symmetrical to a reception beam for the second relay resource.

Abstract: The present invention relates to a Vehicle-to-X (V2X) communication method performed by a terminal in a wireless communication system. The method comprises: determining priority of information related to the V2X communication; selecting a transmission time interval (TTI) on the basis of the priority; and transmitting the information on the basis of the selected TTI. If the information related to the V2X communication is information having high priority, a first TTI is selected, and if the information related to the V2X communication is information having relatively lower priority than the information having high priority, a second TTI is selected.
