Title: MULTI-CELL BEAMFORMING METHOD AND DEVICE
Abstract:
Disclosed are a multi-cell beamforming method and device. The method comprises: by taking maximizing the signal intensity of this coordinated cell scheduling user and minimizing the disclosure of weighting interference of this coordinated cell scheduling user to other coordinated cell scheduling users as principles, calculating beamforming vectors bq of various coordinated cells in a heterogeneous network; and based on a calculation result, updating the beamforming vectors bq of corresponding coordinated cells, so that various coordinated cells conduct data transmission with corresponding scheduling users according to the updated beamforming vectors bq. Data transmission is conducted using the beamforming vectors obtained by calculation by means of the method of the present invention, thereby achieving the optimum balance between the system performance and interference avoidance, improving the validity of interference management, and further improving the system capacity of a low-power node.
