Title (EN) SELECTING AN ACCESS POINT ACCORDING TO A MEASURE OF RECEIVED SIGNAL QUALITY
(FR) SELECTION D'UN POINT D'ACCES EN FONCTION D'UNE MESURE DE LA QUALITE D'UN SIGNAL RECU
Abstract:
(EN) An apparatus for inclusion and a method for operation in a station (STA) of a wireless network. The method includes received data from at least one remote station and determining a measure of the signal quality, e.g., a measure of the EVM from samples of the data received from the remote station(s). If the remote station(s) is/are access point(s), the station selects an access point for association according to criteria that include the measure of the EVM from the remote station. If the received data includes a request management message, the station responds to the request management message with a response management message that include a measure of the EVM of the received data corresponding to the request management message. Thus, the remote station receiving the response management message receives an indication of the quality of the link between the station and the remote station without the receiving remote station necessarily being EVM-capable.
(FR) L'invention concerne un appareil et un procédé utilisés dans une station (STA) d'un réseau sans fil. Le procédé consiste à recevoir des données d'au moins une station à distance, et à déterminer une mesure de la qualité du signal, par exemple une mesure de l'EVM à partir d'échantillons des données reçues de la ou des stations à distance. Si la ou les stations à distance sont des points d'accès, la station sélectionne un point d'accès d'association en fonction de critères comprenant la mesure de l'EVM à partir de la station à distance. Si les données reçues comprennent un message de gestion de demande, la station répond au message de gestion de demande par un message de gestion de réponse comprenant une mesure de l'EVM des données reçues correspondant au message de gestion de demande. La station à distance recevant le message de gestion de réponse reçoit ainsi une indication de la qualité de la liaison entre la station et la station à distance sans que la station à distance de réception soit nécessairement en mesure de déterminer l'EVM.
