The present invention provides a new trigger frame dedicated to NDP feedback procedure. This NDP feedback trigger frame comprises a specific field allowing stations (non-AP nodes) receiving this trigger frame to identify it as being a dedicated NDP feedback trigger frame. Thanks to this specific field, a receiving station knows that a NDP feedback procedure has started and that a NDP feedback is expected by the access point. The present invention also provides for communication methods using this NDP feedback trigger frame, communication device station and access point configured to implement these methods, and also a wireless communication network comprising such devices.
