A node first receives a first signaling and a second signaling, wherein the first signaling and the second signaling are used to determine a first time-domain resource set and a second time-domain resource set; and then transmits a first signal in the first time-domain resource set, and transmits a second signal in a target time-domain resource set; the second time-domain resource set is reserved for transmission of a first bit set, a first bit block comprised in the first bit set being used to generate the second signal; the second time-domain resource set comprises K1 first-type time-domain resource subsets; whether the first time-domain resource set is overlapping with the second time-domain resource set is used to determine time-domain resources comprised in the target time-domain resource set. The present disclosure optimizes the method and device of designs of UCI transmission during PUCCH collisions, thus optimizing the system performance.
