1. A Physical Downlink Control Channel (PDCCH) blind detection method, comprising:
detecting, by a terminal, an energy saving signal in an energy saving signal window;
blindly detecting, by the terminal, the PDCCH within a target time if the energy saving signal is detected, wherein a distance between the target time and a position where the energy saving signal is detected is within a preset time distance range, the target time is an activation time of Discontinuous Reception (DRX);
the energy saving signal window is located before the activation time, and the energy saving signal window includes one or more candidate positions; or
the energy saving signal window includes candidate positions located before the activation time, and further includes candidate positions located within the activation time.
