Abstract
Embodiments of the present disclosure provide a beamforming method and device based on phase shifter switching control, and a system. The method includes: acquiring a channel vector of a channel of each of low-load terminals; acquiring, based on the channel vector, contribution degrees of phase shifters corresponding to the channel; sequentially changing a connected state of each of the phase shifters from closing to opening based on the contribution degrees of the phase shifters corresponding to the channel, calculating a to-be-processed signal-to-interference-plus-noise ratio (SINR) of the low-load terminal after changing the connected state of the phase shifter once, stopping to change the connected state of the phase shifter if the to-be-processed SINR meets a preset condition, and changing the connected state of the phase shifter meeting the preset condition to the closing.
