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: Determining the early arrival path (EAP) based on a channel energy response (CER) can involve the use one or more masks to identify one or more peaks in the CER. Masks can be applied to the CER in an iterative process that can help identify the earliest peak corresponding to the EAP. Alias cancelation may also be implemented.

Abstract: Various methods, apparatuses and articles of manufacture are provided for use by one or more electronic devices to detect and/or respond to certain changes (anomalies) within a wireless signaling environment. For example, a first electronic device may receive a report of a threshold anomaly detected by a monitoring device deployed at a fixed predetermined position within a coverage area of a network service device, and may initiate an investigation by requesting that a second electronic device attempt to monitor certain transmissions of and/or actively communicate with a network service device. In response to a determination based, at least in part, on the investigation that the threshold anomaly represents a threshold change in status within the wireless signaling environment, the first electronic device may transmit a status report regarding the wireless signaling environment to another electronic device.
