Particularly, the method comprises the steps of: receiving a configuration for a resource pool for V2X communication; for a particular wireless resource in a resource pool, when a reception time point of a first ACK/NACK and a transmission time of a second ACK/NACK have been simultaneously configured, determining a use of the particular wireless resource; and transmitting and receiving one ACK/NACK selected from the first ACK/NACK and the second ACK/NACK, on the basis of the use of the particular wireless resource. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.

Abstract: In an embodiment of the present disclosure, proposed is a method in which a first UE transmits a signal to a second UE in a wireless communication system, the method including: a step in which the first UE receives a first signal from the second UE; a step in which the first UE acquires the distance between the first UE and the second UE on the basis of the received first signal; a step in which the first UE selects, on the basis of the calculated distance, a numerology for transmitting a second signal, or a transmit resource in which the numerology is set; and a step in which the first UE transmits the second signal to the second UE on the basis of the selected numerology or the transmit resource. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.
