SUPPORTING HIGH DIMENSIONAL MU-MIMO BEAMFORMING BY SOUNDING MULTIPLE FRAMES WITH DIFFERENT SETS OF ANTENNA PATTERNS

摘要

In some aspects, the disclosure is directed to methods and systems for performing channel estimation between a beamformer and a beamformee. A beamformer can determine that a beamformee is configured to perform channel estimation for up to a pre-configured number of transmit spatial streams from the beamformer. The pre-configured number of transmit spatial streams can be less than a plurality of transmit spatial streams of the beamformer. The beamformer can determine a plurality of subsets of transmit spatial streams from the plurality of transmit spatial streams. The beamformer can send a plurality of sounding frames to the beamformee for channel estimation based at least on the determined plurality of subsets of transmit spatial streams.

1. A method for performing channel estimation between a beamformer and a beamformee, the method comprising:
determining, by a beamformer, that a beamformee is configured to perform channel estimation for up to a pre-configured number of transmit spatial streams from the beamformer, the pre-configured number of transmit spatial streams is less than a plurality of transmit spatial streams of the beamformer; determining, by the beamformer, a plurality of subsets of transmit spatial streams from the plurality of transmit spatial streams; and sending, by the beamformer, a plurality of sounding frames to the beamformee for channel estimation based at least on the determined plurality of subsets of transmit spatial streams.
