DEVICE AND METHOD FOR REDUCED FEEDBACK CHANNEL SOUNDING FOR NEXT GENERATION WIFI

The present invention relates to a channel sounding procedure, particularly a reduced feedback channel sounding procedure for next generation WiFi. To this end, the invention proposes a transmitting device and a receiving device, both configured to support reduced feedback in a channel sounding procedure. The transmitting device is configured to: select at least one of a plurality of feedback types; determine, and send to a receiving device, a feedback indication format, wherein the feedback indication format comprises the selected at least one feedback type and a feedback dependent field based on the selected feedback type; and obtain feedback data from the receiving device, wherein the feedback data bases on the determined feedback indication format sent to the receiving device.
