Multi-user multiple-input multiple-output (MU-MIMO) operation and user selection
System and method of Multi-User Multiple-Input Multiple-Output (MU-MIMO) Beamforming communication. An MU-MIMO BF training session is used to train all the responders in a user group in relation to an initiator having multiple antenna arrays. Accordingly, suitable TX-RX sector pairs are selected based on the training results, and the user group is arranged into subsets such that the initiator can transmit data to the responders in one subset simultaneously by using mutually orthogonal BF waveforms. Prior to the MU-MIMO BF training session, the initiator can select TX sectors of the TX antennas and responders for the training session based on results from a prior or preliminary SISO BF training.
