Abstract:
A method for channel sounding by an access point includes transmitting a sounding frame to a plurality of mobile stations (STAs). The sounding frame includes training symbols to be measured by each of the plurality of STAs. A sounding response frame is received from each of the plurality of STAs. The sounding response frame received from a first STA of the plurality of STAs is received at a short interframe spacing interval delay after completion of the sounding request frame transmission.
