Claim 0:
1. A downlink control channel reception method, applied to a terminal, comprising:
selecting, in a case that monitoring occasions of search spaces transmitted in different Control Resource Sets (CORESETs) configured with different beam directions collide, a target CORESET from the different CORESETs according to types of the search spaces where the collision occurs, wherein the collision during the monitoring occasions comprises that the monitoring occasions are the same and configured resources of the different CORESETs overlap, or, that a time interval between the monitoring occasions is less than a specified threshold; and
detecting and receiving a downlink control channel according to a beam direction of the target CORESET;
wherein, selecting the target CORESET from the different CORESETs according to the types of the search spaces where the collision occurs comprises:
selecting, in a case that at least two of the search spaces where the collision occurs are common search spaces, a CORESET with a lowest index as the target CORESET from at least two CORESETs for transmitting the common search spaces;
or, selecting the target CORESET from the different CORESETs according to the types of the search spaces where the collision occurs comprises:
selecting, in a case that the search spaces where the collision occurs are all UE-specific search spaces, a CORESET with a lowest index as the target CORESET from the different CORESETs.
