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 embodiments facilitate combining a plurality of wireless signal measurement sets with displacement measurements within some time interval of a position request to determine a User Equipment (UE) position. A first set of wireless signal measurements may be obtained from a first set of base stations at a first time at a first location. Subsequently, a second set of wireless signal measurements from a second set of base stations may be obtained at a second time at a second location distinct from the first location. A displacement measurement (e.g. a displacement vector) between the first location and the second location may be obtained. The position of the UE at the second location may then be determined based on the first and second sets of wireless signal measurements and the displacement measurement. In some embodiments, the first and second sets of wireless signal measurements may each be deficient measurement sets.

Abstract: Embodiments of methods and apparatuses for peer discovery in transactional mobile applications are disclosed. In one embodiment, a method of peer discovery includes receiving from a server, at a first device, a meeting location and information for communication with a second device, obtaining a series of location data related to the second device, where the location data is based on a non-device-to-device positioning, determining whether to perform a direct device-to-device positioning with the second device using the meeting location and information for communication with the second device, performing a series of last-stretch direct device-to-device positioning measurements between the first device and the second device in response to a determination to perform the direct device-to-device positioning with the second device, and identifying the second device based on the series of last-stretch device-to-device positioning measurements between the first device and the second device.

Abstract: Systems, methods, apparatuses, and computer-readable media for adaptive wake-up scheduling under PRS muting are disclosed. For example, A mobile device can measure a plurality of reference signals for positioning having a muting pattern cycle comprising two or more time periods. The mobile device, during an evaluation phase, can receive during one or more evaluation time periods within the muting pattern cycle, reference signals detectable by the mobile device during the one or more evaluation time periods within the muting pattern cycle. The mobile device can determine a subset of the muting pattern cycle for measuring reference signals, where the subset of the muting pattern cycle comprises a number of time periods fewer than the two or more time periods of the muting pattern cycle. The mobile device then measures reference signals only during the determined subset of the muting pattern cycle.

Abstract: A mobile device synchronously scans different terrestrial networks for positioning measurements to align the scans in time. With minimal time difference between the scans, the positioning measurements from the different terrestrial networks may be used for crowdsourcing or position determination. The mobile device may synchronously scan a wireless wide area network (WWAN) and a local area wireless network so that positioning measurement derived from the scans are aligned in time. A local area wireless network is, e.g., a wireless local area networks (WLANs) or wireless personal area network (WPANs) but does not include cellular networks or satellite networks. The scans may be scheduled at a hardware level to ensure tight synchronization with near-zero time difference between the scans. Alternatively, the scans may be synchronized at a software level with only scans that occur within a time difference threshold from each other are used for crowdsourcing or positioning.
