Abstract: Systems and methods are provided for frame burst overlapping basic service set (OBSS) handling. In various embodiments, the disclosed methods and systems provide for synchronizing access points (APs) in the same channel. Based on the synchronizing, the APs in the same OBSS channel can determine a distribution policy for using frame bursting. Each AP can use frame bursting in accordance with the distribution policy. In various embodiments, the APs can periodically send frame burst synchronization packets. The frame burst synchronization packets can indicate respective numbers of client devices associated with each AP. Based on the frame burst synchronization packets sent by the APs, a total number of client devices using the same channel can be determined. The distribution policy for using frame bursting can be determined based on the total number of client devices.

Abstract: Examples described herein provide coordinated ranging between APs in a network. Examples described herein may receive, by a computing device, neighbor adjacency information for a plurality of access points (APs) in a network, and based on the neighbor adjacency information, assign, by the computing device, subsets of the plurality of APs to non-overlapping zones. Examples described herein may initiate, by the computing device for each of the non-overlapping zones, ranging measurements between the subset of APs in the zone to generate a ranging result, wherein the ranging measurements between the subsets of APs in the non-overlapping zones are performed in parallel. Examples described herein may, based on the ranging results, resolve, by the computing device, locations of the plurality of APs.

Abstract: Examples of techniques for handling fine time measurement ranging requests are described. In an example, an access point (AP) may receive a ranging request for initiating a Fine Timing Measurement (FTM) session. Responsive to determining that the client device is associated with the AP, it is determined that the ranging request is received after a threshold time from expiry of an FTM burst period of the client device. It is determined that the ranging request is within an FTM acceptance threshold of the AP. A number of consecutive unsuccessful FTM bursts between the AP and the client device is determined. In response to determining that the number of consecutive unsuccessful FTM bursts is less than an unsuccessful burst threshold of the AP, the FTM session may be initiated based on the ranging request.

Abstract: Examples of techniques for handling multiple fine time measurement ranging requests are described. In an example, an access point (AP) may receive a ranging request for initiating an FTM session from each client device in a set of client devices. Based on the ranging request, a plurality of burst durations, each for performing the FTM session for each client device is determined. A maximum burst duration may be determined form the plurality. If a service time for serving high priority traffic is less than the maximum burst duration, a subset of the client devices is selected for performing the FTM session, where a sum of burst durations for performing the FTM session for each client device in the subset is less than the maximum burst duration. The FTM session for each client device in the subset is initiated.
