    Abstract: A method by which a terminal transmits feedback information comprises the steps of: determining, in predetermined resource units for receiving the broadcast information in a broadcast resource region, whether broadcast information collides; selecting a first shared resource in a shared resource region corresponding to a first broadcast resource in which the conflict occurs in the broadcast resource region, on the basis of a pre-defined mapping rule of the broadcast resource region and the shared resource region; and transmitting, in the selected first shared resource, feedback information including information on the occurrence of the collision, wherein the broadcast resource region is a resource region, which is defined so as to transmit or receive the broadcast information, and the shared resource region can be determined as a resource region shared between a plurality of terminals. 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.
