Abstract: Various embodiments include methods and a server implementing the methods for generating crowd-sourced navigation data. The methods may include receiving, by a server, location data from a plurality of wireless communication devices, and generating, by the server, topological map data based on the location data received from the plurality of wireless communication devices. The location data received from the plurality of wireless communication devices may include an altitude, a latitude, and a longitude, and at least one of a medium access control address, a time stamp, a round trip time, a received signal strength indicator value, a reference signal received power value, a reference signal receive quality value, and a service set identifier. Methods may further include receiving location data from an unmanned aerial vehicle (UAV), generating navigation data relevant to the UAV using the generated topological map data, and transmitting the navigation data to the UAV.

Abstract: A method of associating environmental context with wireless access points is disclosed. In some embodiments, a method on a user equipment may comprise determining at least one environmental context associated with a subset of one or more Access Points (APs) visible to the UE at an estimated location of the UE. The at least one environmental context associated with the subset may be determined based on one or more of wireless measurements by the UE, and/or sensor measurements by the UE. Further, at least one AP cluster may be determined by clustering the subset of the one or more APs visible to the UE based on the at least one environmental context and the estimated location. Environmental context for APs may be crowdsourced and stored and provided to a UE as location assistance information to facilitate location determination and other functions.

Abstract: Disclosed is a system, apparatus, computer readable storage medium, and method to perform a bandwidth efficient network based positioning (NBP). A positioning request for a mobile device is received within an environment, the environment comprising one or more access points (APs). An AP coverage area including the mobile device is determined A NBP load for the AP is measured, wherein the NBP load comprises a direct NBP load and an indirect NBP load. If the NBP load is less than a threshold, the AP is instructed to process the first positioning request. Multiple APs may process positioning requests concurrently and positioning requests may be scheduled according to timeout and/or relative expiration.
