METHOD AND APPARATUS FOR INITIATING CHANNEL SOUNDING WITH UNASSOCIATED ACCESS POINTS

摘要

A system and method are disclosed that may allow a STA to request one or more non-associated APs to initiate channel sounding operations with the STA. In response to the request, a number of the non-associated APs may send one or more NDPs to the STA. The STA may use the received NDPs to determine a goodput value for each of the number of non-associated APs. The STA may then use the determined goodput values to select one of the number of non-associated APs with which to associate. Thereafter, the STA may initiate an association operation with the selected AP.

主权项

1. A method performed by a mobile station (STA) for selecting an access point (AP) with which to associate, the method comprising:
broadcasting a probe request that includes a request for one or more non-associated APs to initiate a channel sounding operation with the STA; receiving, from each of a number of the non-associated APs, a null data packet (NDP); determining, for each of the number of non-associated APs, a goodput value based, at least in part, on a corresponding one of the received NDPs; and selecting one of the number of non-associated APs for an association operation with the STA based, at least in part, on the determined goodput values of the number of non-associated APs.
