The present invention relates to a method and apparatus for transmitting and receiving an acknowledgement/negative-acknowledgement (ACK/NACK) by a terminal for vehicle-to-everything (V2X) communication in a wireless communication system. 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.
