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

Abstract
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.
