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.
