Abstract: The present disclosure provides a method and a device in a node for wireless communications. A first node determines a first resource set and a first resource set group from M resource sets; and monitors a first-type channel in the first resource set group in a first time window. Any two of the M resource sets are overlapping in time domain, and the first resource set group comprises the first resource set; any of the M resource sets is linked to one or two spatial states; a second resource set is any of the M resource sets different from the first resource set; whether a first condition is fulfilled is used to determine whether the second resource set belongs to the first resource set group. The above method avoids performance loss resulting from the UE's unnecessary abandonment of monitoring over some PDCCH candidates.
