SOUNDING DESIGN FOR CHANNEL FEEDBACK

摘要

Aspects of the present disclosure provide techniques for sounding procedures using frames with some portions that use relatively long symbol durations. Certain aspects of the present disclosure provide a method that may be performed by an access point. The method generally includes generating one or more frames, collectively having one or more training fields allowing one or more stations to calculate channel information and an indication of one or more feedback parameters for the one or more stations to use for generating the channel information; transmitting the one or more frames; and receiving channel information from at least one of the stations calculated, in accordance with the one or more feedback parameters, for a corresponding one or more reporting units based on the one or more training fields, wherein the channel information is received via a report containing a plurality of channel information parameters for each of the one or more reporting units.
