1. A search space monitoring method implemented by a terminal, wherein the search space monitoring method comprises:
determining M candidate monitoring occasions of a search space, wherein M is a positive integer;
determining N target monitoring occasions from the M candidate monitoring occasions based on a time domain location of an on duration of a discontinuous reception (DRX) cycle,
wherein N is a positive integer less than or equal to M, wherein the N target monitoring occasions are N candidate monitoring occasions in a time window, wherein a first difference between a start time of the time window and a start time of the on duration is equal to a second preset value, and
wherein a second difference between an end time of the time window and the start time of the on duration is equal to a third preset value; and
monitoring, on the N target monitoring occasions, a power saving signal indicating power saving information of the terminal.
