Dynamic control of channel sounding for transmit beamforming

摘要

The present disclosure discloses a system and method for dynamic control of channel sounding for transmit beamforming. Generally, sounding frames are periodically transmitted by a network device to a particular device at a first sounding interval. First feedback information is received from the particular device. The first feedback information corresponds to the sounding frames transmitted at the first sounding interval. Based on one or more current conditions included in the feedback information, a second sounding interval is selected to transmit the sounding frames to the particular device. The sounding frames are periodically transmitted to the particular device at the second sounding interval. Second feedback information is received from the particular device. The second feedback information corresponds to the sounding frames transmitted at the second sounding interval.

1. A non-transitory computer readable medium comprising instructions which, when executed by one or more devices, causes performance of operations comprising:
periodically transmitting, by a network device, sounding frames to a particular device at a first sounding interval, wherein the first sounding interval refers to a first interval of time between transmission of sounding frames; receiving from the particular device a first feedback matrix corresponding to the sounding frames transmitted at the first sounding interval; based on one or more current conditions included in the first feedback matrix, selecting a second sounding interval to transmit the sounding frames to the particular device, wherein:
the second sounding interval refers to a second interval of time between transmission of sounding frames; andthe second sounding interval is different than the first sounding interval; computing a steering matrix to direct the sounding frames to the particular device at the second sounding interval, wherein the steering matrix is calculated based on the first feedback matrix; periodically transmitting the sounding frames to the particular device at the second sounding interval; and receiving from the particular device a second feedback matrix corresponding to the sounding frames transmitted at the second sounding interval.
