Disclosed in the present application are a method and apparatus used in a node for
wireless communication. The apparatus comprises: a first
receiver, which receives first information and first signaling, wherein the first information is used for determining that a first PDCCH candidate and a second PDCCH candidate are associated with each other, and both the first PDCCH candidate and the second PDCCH candidate are used for carrying the first signaling; and a first
transmitter, which sends a first PUSCH, a frequency-domain resource occupied by the first PUSCH belonging to a target frequency-domain
resource pool, wherein the first signaling is used for determining, from the target frequency-domain
resource pool, the frequency-domain resource occupied by the first PUSCH, and the target frequency-domain
resource pool is one of a plurality of frequency-domain resource pools; and a reference PDCCH candidate is one of the first PDCCH candidate or the second PDCCH candidate, and the reference PDCCH candidate is used for determining the target frequency-domain resource
pool from among the plurality of frequency-domain resource pools.
