Patent attributes
Embodiments provide a power adjustment method and an access network device, and the embodiments relate to the field of communication technologies. A target power increase value is adaptively determined based on a target key characteristic of a target cell, so that a cell coverage loss and a cell capacity loss caused by channel shutdown are compensated for, and a good energy-saving effect is obtained. The access network device blocks transmit channels that are of some of a plurality of antennas and that correspond to the target cell. Then, the access network device obtains the target key characteristic of the target cell, and determines the target power increase value based on the target key characteristic. The access network device increases, based on the target power increase value, transmit power of the access network device corresponding to the target cell or a target user.
