Abstract: Disclosed is a method by which a terminal transmits an acknowledgement (ACK)/negative ACK (NACK) signal in a wireless communication system. In particular, the method is characterized by receiving data from a base station, generating an ACK signal or a NACK signal corresponding to the data, transmitting the ACK signal to the base station on the basis of a first hopping pattern when the ACK signal is generated according to the data, and transmitting the NACK signal to the base station on the basis of a second hopping pattern different from the first hopping pattern when the NACK signal is generated according to the data. The terminal is capable of communicating with at least one of another terminal, a terminal related to an autonomous driving vehicle, the base station or a network.
