Abstract[English]
An access point, AP (110), configured to perform a sounding procedure with one or more associated non-AP stations (120) in a wireless local area network (100) is provided. The AP (110) comprises a processing circuitry (111) configured to generate a null data PPDU announcement, NDPA, frame, wherein the NDPA frame comprises for each of the one or more associated non-AP stations (120) a station info field. The station info field comprises a partial BW info subfield, including a feedback bitmap and an indication of a resolution and/or a range of the feedback bitmap with a 20 MHz or 40 MHz subchannel resolution for a Sounding NDP with a bandwidth of up to 320 MHz. The AP (110) further comprises a communication interface (113) configured to transmit the NDPA frame to the one or more associated non-AP stations (120). Moreover, a corresponding non-AP station (120) is disclosed.[French]
La présente invention concerne un point d'accès, AP (110), configuré pour réaliser une procédure de sondage avec une ou plusieurs stations non-AP (120) associées dans un réseau local sans fil (100). Le point d'accès (110) comprend des circuits de traitement (111) configurés pour générer une trame d'annonce PPDU de données nulles, NDPA, la trame NDPA comprenant un champ d'information de station pour chacune de la ou des stations non-AP (120) associées. Le champ d'information de station comprend un sous-champ d'information de largeur de bande partielle, incluant des bits de rétroinformations et une indication d'une résolution et/ou d'une plage des bits de rétroinformations avec une résolution de sous-canal de 20 MHz ou 40 MHz pour un paquet NDP de sondage ayant une largeur de bande jusqu'à 320 MHz. L'AP (110) comprend en outre une interface de communication (113) configurée pour transmettre la trame NDPA à la ou aux stations non-AP (120) associées. La présente invention concerne en outre une station non-AP (120) correspondante.
