1. A physical downlink control channel detection method, applied to a terminal and comprising:
obtaining at least two search space groups and a switch condition, wherein the at least two search space groups comprise a first search space group and a second search space group; and
switching between the first search space group and the second search space group according to the switch condition, for PDCCH detection;
wherein the switch condition comprises a first switch condition for switching from the first search space group to the second search space group for PDCCH detection, and the first switch condition comprises:
switching to the second search space group for PDCCH detection in a preset time length after a time when a PDCCH that meets a preset condition is detected;
wherein the preset time length is longer than or equal to a processing latency of the PDCCH.
