摘要： A first node receives a first signaling; and transmits a first signal and a second signal respectively in a first time-domain resource block and a second time-domain resource block. The first time-domain resource block and the second time-domain resource block both belong to a reference time window; the first node maintains power consistency and phase continuity between multiple first-type signals that belong to a same first-type time window in time domain; whether a first condition set is satisfied is used to determine a number of first-type time window(s) comprised by the reference time window; the first condition set comprises a first condition, the first condition comprising that the first node transmits a third signal in a third time-domain resource block and the third time-domain resource block is overlapped with only one of the first time-domain resource block or the second time-domain resource block.
