Abstract: Provided is a method for transmitting a signal by means of a sidelink terminal in a wireless communication system, according to an embodiment of the present invention. The method for transmitting a signal comprises the steps of: selecting any one of an eNB and a gNB as a synchronization reference; and transmitting a sidelink channel/signal including an SSB (SS/PBCH block) on the basis of synchronization of the base station selected as the synchronization reference, wherein when dual connectivity (DC) is configured for the terminal, the terminal selects a master NB (NodeB) among the eNB as the synchronization reference. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, the BS or a network.

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.

Abstract: The present invention relates to a method and apparatus for feeding back acknowledgement/negative-ACK (ACK/NACK) by a receiving device in a wireless communication system. Specifically, the method comprises the steps of: receiving data from a transmitting device; and feeding back ACK/NACK for data to the transmitting device, wherein the size of resource for ACK/NACK is determined on the basis of a distance between the transmitting device and the receiving device. The receiving device is capable of communicating with at least one of another transmitting device, a transmitting device related to an autonomous driving vehicle, a base station or a network.
