METHOD AND DEVICE IN NODES USED FOR WIRELESS COMMUNICATION
The present disclosure provides a method and device in a node for wireless communications. A first node determines a first resource set and a first resource set group out of M resource sets; monitors a first-type channel in the first resource set group in a first time window. Any two of the M resource sets are overlapped in time domain, and the first resource set group comprises the first resource set; any of the M resource sets is connected to one or two spatial states; a reference resource set is any of the M resource sets different from the first resource set; whether the reference resource set satisfies a first condition is used to determine whether the reference resource set belongs to the first resource set group. The above method avoids the performance loss incurred by UE's unnecessary dropping the monitoring on some PDCCH candidates.
