When a remote station is an access point, as for the station concerned, the access point for correlation is chosen based on the standard containing the measure of EVM from a remote station. When the data received [above-mentioned] contains a request administrator message, the station concerned answers with the response management message which contains the measure of EVM of the received data corresponding to this request administrator message to this request administrator message. In this way, the this received remote station does not necessarily need to be EVM correspondence, and the remote station which receives this response management message will receive the index of the quality of the link between the above-mentioned station and the above-mentioned remote station.
