Method and Apparatus for Sounding Multiple Stations

摘要

One or more stations to provide sounding feedback in response to a training signal sequence are determined, and a schedule for the one or more stations to provide sounding feedback is determined based on capabilities of the one or more stations to transmit sounding feedback at a defined time period after an end of the training signal sequence. A communication frame is generated that includes i) an indication of a request for the plurality of stations to provide sounding feedback corresponding to the training signal sequence, and ii) an indication of when the one or more stations are to transmit sounding feedback. The communication frame is transmitted along with the training sequence.
