Abstract: An embodiment of the present invention relates to a method for a UE transmitting a signal in a wireless communication system supporting a plurality of transmission time interval (TTI) lengths, wherein the signal transmission/reception method comprises the steps of: performing a measurement for each first-TTI resource unit; selecting a first-TTI resource that is the closest to first-TTI resources having measurement results that are greater than or equal to a preset value on the time axis; and transmitting a signal using the selected first-TTI resource. 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: An embodiment of the present invention relates to a method in which a first terminal transmits/receives a message including platoon information in a wireless communication system. The method include: a step for receiving, by a first terminal, resource information from a second terminal in a terminal group forming a platoon; a step of transmitting, by the first terminal, a Cooperative Awareness Message (CAM) including the platoon information after receiving the resource information, wherein when the platoon information is for a terminal not belonging to the terminal group, the first terminal transmits the CAM message through a resource instructed in the resource information.
