Abstract: A PDCCH blind detection method, a terminal and a network side device are provided. The method includes: 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, a distance between the target time and a position where the energy saving signal is detected is within a preset time distance range.
