This invention presents a method and systems for beamforming in wireless communication comprising a base station with a plural of antennas and radio frequency transmitting and receiving chains, a plural of base band transmitting paths and base band receiving paths, and a processor that constructs a subspace for each user equipment using the principal angle information contained in partial channel state information obtained on channels associated with a part of the BS antennas, derives an analog beamforming matrix and/or an analog combining matrix from the subspaces of all the user equipment selected for communication with the base station to achieve analog beamforming, and further performs beamforming at the base band.
