1. A method for determining a control channel, comprising:
receiving, by a terminal, at least one first control resource set (CORESET) information; and
receiving, by the terminal, a physical downlink control channel (PDCCH) based on at least one second CORESET information, wherein the at least one second CORESET information is determined based on the at least one first CORESET information and a first resource, and the at least one second CORESET information corresponds to the first resource;
wherein the first resource comprises a first time-domain resource, and correspondence between the at least one second CORESET information and the first resource comprises:
the second CORESET information being valid on the first time-domain resource;
wherein the first CORESET information is switched to the second CORESET information on the first time-domain resource;
wherein the first resource comprises a first frequency-domain sub-band and a second frequency-domain sub-band;
the at least one first CORESET information corresponds to the first frequency-domain sub-band, and the at least one second CORESET information corresponds to the second frequency-domain sub-band; and
the first frequency-domain sub-band and the second frequency-domain sub-band belong to different bandwidth parts (BWPs).
