Abstract

The present invention proposes a method, device and base station for cooperative beam forming based on MBMS fixed grid of beams GoB. The cooperative beam forming method comprises following steps: grouping users into cell central user group and cell edge user group (S701); performing cell central user group multiplexing based on superposition coding (S702); performing cooperative beam forming operation based on fixed grid of beams GoB for cell edge user group (S703).
