Abstract: In one aspect, a method includes performing, by a wireless station, a fine timing measurement (FTM) procedure with each of one or more FTM-enabled access points (APs) to obtain a respective one or more FTM-based round-trip time (RTT) measurement between the wireless station and each of the one or more FTM-enabled APs. The method also includes performing a non-FTM procedure with each of one or more non-FTM-enabled APs to obtain a respective one or more non-FTM-based RTT measurement. The wireless station then calculates a position of the wireless device based on both the one or more FTM-based RTT measurements and the one or more non-FTM-based RTT measurements.

Abstract: Embodiments of the disclosure are directed to the use of supplemental information received from Vehicle-to-Everything (V2X) capable entities in order to enhance navigation and route selection based on available advanced driver assistance systems (ADAS) functionality. A number of potential routes are evaluated by retrieving the V2X capabilities and locations from V2X capable entities along those routes. That information is used to assess traffic density and availability of supplemental information used by ADAS along each route, allowing for an evaluation of each route on travel time and ADAS support. The driver can then select the best route that supports their needs.

Abstract: A method of using one or more radio-frequency signals includes: monitoring, with at least one radio-frequency (RF) receiver, one or more RF characteristics of one or more wireless RF signals from one or more RF devices in an environment; comparing the one or more RF characteristics to a reference RF profile for the environment; and initiating an action based on a difference between the one or more RF characteristics and the reference RF profile determined by the comparing.

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: A user equipment (UE) may receive Vehicle-to-Everything (V2X) information from a V2X entity, such as a vehicle, road side unit, or other UE carried by a pedestrian. The V2X information may be transmitted to a location server by the UE to obtain positioning assistance data. The location server may determine a coarse position of the UE using the V2X information and generate corresponding positioning assistance data including Positioning Reference Signal (PRS) information for neighbor base stations, which is transmitted to the UE. The UE may detect PRS signals from the neighbor base stations and perform position determination using the PRS signals. The V2X entity or a different V2X entity may also transmit PRS signals that are received by the UE and used along with the PRS signal from the neighbor base stations to perform position determination.

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: In one aspect, a method includes performing, by a wireless station, a fine timing measurement (FTM) procedure that includes exchanging one or more FTM messages between the wireless station and an access point to obtain a first round-trip time (RTT) between the wireless station and the access point. The method also includes performing, by the wireless station, a non-FTM procedure to obtain a second RTT between the wireless station and the access point. The wireless station then calculates a turn-around calibration factor (TCF) estimate of the access point based on a difference between the second RTT and the first RTT. Data representative of the TCF estimate of the access point may then be sent to a server.

Abstract: Disclosed are devices, systems and methods for combining observations obtained at two different mobile devices attached to a human user for performing a navigation operation. For example, observations of a signal acquired at a first mobile device may be selected for computing a position fix based, at least in part, on a utility indicator associated with the observations.

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.
