Multi-user multi-stream beamforming method, apparatus, and base station

摘要

The present invention relates to a multi-user multi-stream beamforming method and apparatus, and a base station. The multi-user multi-stream beamforming method includes the steps of: a) calculating a beamforming matrix of each user in the multi-user according to a minimum leakage principle; b) determining a user average Signal to Leakage Noise Ratio (SLNR) of the multi-user according to the beamforming matrix of each user; c) determining whether the user average SLNR is stable, and if the user average SLNR is not stable, returning to step a) to recalculate the beamforming matrix of each user by using the calculated beamforming matrix of each user.
