Abstract: A method and a base station for implementing coordinated beamforming are disclosed. The method includes: a base station acquiring a transmitting beamforming vector in a current time slot according to a receiving beamforming vector estimate value of each interference terminal; shared in a previous time slot; and each base station acquiring a receiving beamforming vector estimate value in the current time slot according to the transmission beamforming vector in the current time slot and an interference vector shared in the previous time slot, and sharing the acquired receiving beamforming vector estimate value and an interference vector in the current time slot. The technical scheme provided by the embodiment of the present document considers the receiving beamforming vector in an associated coordinated beamforming scheme based on a maximized SLNR criterion, and only two kinds of information, i.e., receiving beamforming vector estimate value and interference vectors are shared between coordinating base stations.
