1. A method for sending a physical downlink control channel, comprising:
determining, from a candidate search space set for the physical downlink control channel (PDCCH) multiple repetition transmissions, a search space for sending the PDCCH, wherein the candidate search space set for the PDCCH multiple repetition transmissions comprises all search spaces or at least one search space in one time unit; and
sending the PDCCH based on the determined search space;
wherein the candidate search space set for the PDCCH multiple repetition transmissions comprises two or more search spaces; at least two search spaces of the two or more search spaces correspond to different first configuration parameters; and
the two or more search spaces correspond to the same searchSpaceId, or some or all of the two or more search spaces correspond to different searchSpaceIds respectively; and
the first configuration parameter at least comprises candidate transmission locations of the PDCCH corresponding to each aggregation level in the aggregation level set.
