1. A Physical Downlink Control Channel (PDCCH) detection method performed by a User Equipment (UE), the PDCCH detection method comprising:
receiving a relevant parameter of a PDCCH monitoring window, wherein the parameter comprises at least one of the quantity of time domain units in the PDCCH monitoring window, or the quantity of Monitoring Occasions (MOs) in the PDCCH monitoring window;
determining the PDCCH monitoring window in accordance with the parameter; and
detecting and receiving a PDCCH within the PDCCH monitoring window,
wherein in the case that the parameter comprises the quantity of time domain units in the PDCCH monitoring window, the determining the PDCCH monitoring window comprises determining all search space monitoring time domain positions in the PDCCH monitoring window in accordance with a first association relationship between serial numbers of the time domain units where the MOs in a search space are located and the quantity of time domain units in the PDCCH monitoring window; or
wherein in the case that the parameter comprises the quantity of time domain units in the PDCCH monitoring window, the determining the PDCCH monitoring window comprises determining all time domain units in the PDCCH monitoring window in accordance with a second association relationship between serial numbers of the time domain units and the quantity of time domain units in the PDCCH monitoring window.
