Title: WIRELESS NETWORK POSITIONING
Abstract:
Disclosed embodiments facilitate efficient positioning of stations (STAs) on wireless networks. A method on an Access Point may determine, at a first time, availability of the Access Point (AP) for positioning; and transmit, based at least in part, on the determination, information indicative of the AP's availability for positioning. The transmitted information may comprise one or more of: STA-AP location determination availability, STA-AP location determination capability, whether AP-AP positioning is being performed; and/or the next scheduled AP-AP ranging session. In some embodiments, a STA may initiate location determination to determine a location of the STA based, at least in part, on indications of availability for positioning for one or more Access Points (APs) communicatively coupled to the STA. Each indication of availability may correspond to a distinct AP of the one or more APs, and the location determination may comprise either: STA-AP location determination, or passive location determination.
