    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.

    Abstract: In some aspects, the disclosure is directed to methods and systems for transmitting to static and non-static devices. An access point having a plurality of antennas can send a plurality of sounding frames from the plurality of antennas to a plurality of devices. The access point can identify, based on responses to the plurality of sounding frames, at least one static device from the plurality of devices. The access point can assign, based on the responses to the plurality of sounding frames, to each of the at least one static device, a corresponding one of the plurality of antennas for operation in a directional mode for transmissions to the corresponding static device, and the remaining antennas from the plurality of antennas for operation in an omnidirectional mode.

    Abstract: Systems and methods can analyze a present channel estimation and a previous channel estimation and/or two or more prior channel estimations to improve communication performance, sense environmental conditions, and make location and velocity determinations. The methods can include: (a) sending, by a transmitter, a first sounding frame and a second sounding frame to a receiver; (b) receiving, by the transmitter, a first channel estimation response from a receiver responsive to the first sounding frame, and a second channel estimation response from the receiver responsive to the second sounding frame; and (c) detecting, by the transmitter, based at least on the first channel estimation response and the second channel estimation response, if a change in characteristics of a channel between the transmitter and the receiver occurred between the first sounding frame and the second sounding frame.
