The method comprises: determining mutually interfering wave beams between a cell of a first base station and a cell of a second base station based on first interference information and second interference information, the first interference information comprising a first cell set, the first cell set comprising a first interference cell to which the interference wave beam of a wave beam of the cell of the first base station belongs, the second interference information comprising a second cell set, and the second cell set comprising a second interference cell to which the interference wave beam of a wave beam of the cell of the second base station belongs; coordinating time-frequency resources, time domain resources or frequency domain resources occupied when the mutually interfering wave beams between the cell of the first base station and the cell of the second base station are sent, so as to reduce interference. The technical solution may provide a method for interference coordination. By coordinating, wave beams of the cells of the base stations are sent in a staggered manner in terms of the time-frequency resources, the time domain resources or the frequency domain resources, thereby reducing the mutual interference between the wave beams of the cells of the base stations without increasing uplink costs.
