Abstract: Methods and apparatus are described by which a wireless station transmits information to an access point in response to a short feedback request. The response to the short feedback request is transmitted as either energy or lack thereof in one or more long training fields transmitted in a preamble of a physical layer packet. Short feedback trigger frames for requesting the short feedback are also described.
