Channel aggregation level allocation method and device, base station and storage medium

The invention provides a channel aggregation level allocation method and device, a base station and a storage medium. The method comprises the following steps: determining a first ratio corresponding to the total DTX frequency of a PDSCH and a PUSCH in a previous first detection period; in a second detection period, sending a detection PDCCH and a corresponding detection PDSCH to the terminal based on a second aggregation level of the PDCCH lower than the first aggregation level of the currently allocated PDCCH of the terminal; and determining a second proportion value corresponding to PDSCH DTX detection in a second detection period, and determining a PDCCH aggregation level allocated to the terminal. According to the method and the device, the problem that PDCCH resources are limited during service deployment can be solved, the condition that PDCCH receiving or demodulation fails can be reflected more accurately by using the detection indexes, accurate allocation of aggregation levels can be realized, and t
