Title: METHOD AND BASE STATION FOR ENABLING BEAMFORMING
Abstract:
A method and base station for enabling beamforming, wherein the method for enabling beamforming comprising: establishing a downlink beam optimization model according to an integrated channel error model and a downlink model; obtaining an optimal beamforming matrix optimization goal according to the established downlink beam optimization model; respectively obtaining the channel matrixes of the service cell in which the base station is located and the cells exclusive of the service cell in the cooperative cluster in which the base station is located and the nonideal parameters respectively corresponding to each channel matrix; obtaining a beamforming matrix for the base station according to the obtained channel matrixes and the nonideal parameters respectively corresponding to each channel matrix and the optimal beamforming matrix optimization goal, the base station transmitting downlink data according to the obtained beamforming matrix. The beamforming method and base station effectively suppress TDD system channel error, eliminate complex iteration calculation steps, and can effectively suppress inter-cell interference.
