Abstract: A method and an apparatus for balancing power between antennas, and a base station are provided. The method includes multiplying n virtual antenna signals by an orthogonal matrix to obtain n intermediate regulative signals; and using a corresponding rotary phase to rotate phases of m of the n intermediate regulative signals, so that a phase difference exists between at least two of n physical antenna signals output by antennas.
