1. A method for channel sounding by an access point, comprising:
- transmitting a sounding frame to a plurality of mobile stations (STAs), wherein the sounding frame includes training symbols to be measured by each of the plurality of STAs; and
receiving a sounding response frame from each of the plurality of STAs, wherein 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 frame transmission.

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.

12. An access point (AP), comprising:
-
a processor configured to generate a sounding frame to sound a channel between the AP and a plurality of mobile stations (STAs), wherein the sounding frame includes training symbols to be measured by each of the plurality of STAs; a transmitter configured to transmit the sounding frame to the plurality of STAs; and a receiver configured to receive a sounding response frame from each of the plurality of STAs, wherein the sounding response frame received from a first STA of the plurality of STAs is received at a short interframe spacing interval delay after completing transmission of the sounding frame.

13. A method for channel sounding by a mobile station (STA), comprising:
-
receiving a sounding frame from an access point (AP), wherein the sounding frame includes training symbols to be measured by the STA; on a condition that the sounding frame includes an address of the STA, transmitting a sounding response frame to the AP; and on a condition that the sounding frame does not include an address of the STA, setting a network allocation vector based on information included in the sounding frame. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

21. A mobile station (STA), comprising:
-
a receiver configured to receive a sounding frame from an access point (AP), wherein the sounding frame includes training symbols to be measured by the STA; a processor configured to; process the sounding frame to determine whether the sounding frame includes an address of the STA; and set a network allocation vector based on information included in the sounding frame on a condition that the sounding frame does not include an address of the STA; and a transmitter configured to transmit a sounding response frame to the AP on a condition that the sounding frame includes an address of the STA. - View Dependent Claims (22)
