This application provides a beam selection method and apparatus, and a storage medium. The method includes: separately measuring a sounding reference signal SRS sent by at least one terminal, to determine a first spectral efficiency of each terminal; calculating a second spectral efficiency of each beam group based on the first spectral efficiency of each terminal, where each beam group includes at least one beam, and each beam covers at least one terminal; and determining a target beam group based on the second spectral efficiency of each beam group.
