Method for v2x communication performed by means of terminal in wireless communication system and terminal using same

The present invention relates to a method for V2X (vehicle-to-everything) communication performed by means of a terminal in a wireless communication system, the method characterized by: determining whether or not the transmission points of feedback information for sidelink semi-persistent scheduling (SPS) information and feedback information for a wide area network (WAN) physical downlink shared channel (PDSCH) overlap; and transmitting the feedback information for the sidelink SPS information and the feedback information for the WAN PDSCH on the basis of the determination, wherein, if the transmission points of the feedback information for the sidelink SPS information and the feedback information for the WAN PDSCH overlap, the feedback information for the sidelink SPS information and the feedback information for the WAN PDSCH are transmitted by means of multiplexing or transmitted on the basis of priority.
