Synthesized beam-forming method and system for SC MBMS transmission

Beamforming provides a system and method for MBMS transmission. The method comprising: obtaining the information of each user through an uplink DoA estimation; calculating beamforming weighting coefficients based on information obtained DoA; The beamforming weighting coefficients to generate a composite weighting factor. The method further comprises determining the number of users. When it is determined that the number of MBMS users is less than a predetermined threshold value, calculated according to all the DoA information received beamforming weighting coefficient; when it is determined that the number of MBMS users is larger than a predetermined threshold value, the first of DoA information obtained grouping from each group selected DoA information to calculate a beamforming weighting coefficient.
