Claim 6:
7. A network side device, configured to perform the downlink control channel transmission method according to claim 6, comprising a transceiver, a storage, a processor and a computer program stored in the storage and executable by the processor; wherein,
the processor is configured to, in a case that the occasions of transmissions of the downlink control channel that requires to be performed in different CORESETs configured with different beam directions collide, select the target CORESET from the different CORESETs according to the types of the search spaces in the different CORESETs where the collision occurs; the transceiver is configured to transmit the downlink control channel according to the beam direction of the target CORESET; or,
the transceiver is configured to transmit the downlink control channel in the different CORESETs according to respective beam directions of the different CORESETs;
wherein the collision during the occasions of the transmissions of the downlink control channel comprises: that the occasions of the transmissions of the downlink control channel are the same and the configured resources of the different CORESETs overlap, or, that the time interval between the transmissions of the downlink control channel is less than the specified threshold;
wherein the processor is configured to select, 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 the processor is configured to select, 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.
