    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: A level 3 (L3) sparse network almanac (SNA) is generated using data from a base station almanac with information for a plurality of base stations. The information for base stations includes cell identifiers that include an L3 region code that is one layer above a cell tower identification level. Cell boundaries are determined from the base station information. The cell boundaries are used to estimate a region of coverage for the L3 SNA, which may be stored in a database. For example, region points may be generated from the cell boundaries, and used to estimate the region of coverage for the L3 SNA. The region of coverage may be determined, e.g., as a minimum enclosing circle or other similar techniques. The larger of an estimated region size parameter, e.g., a radius of a circle, and a default size may be used for the region of coverage.

    Abstract: Techniques are provided, which may be implemented via various methods, apparatuses, and/or articles of manufacture. For example, an electronic device may obtain an estimated location of a mobile device, determine a quality of a geometric distribution of transmitting devices capable of transmitting wireless signals to the mobile device at the estimated location, and assign an uncertainty to the estimated location. In certain implementations, an electronic device may further determine an adapted transmission setting for a transmitting device and transmit a corresponding message to the transmitting device. In certain implementations, an electronic device may identify adapted assistance data for the mobile device and transmit a corresponding message to one or more other electronic devices.

    Abstract: Systems and methods are disclosed for determining the floors on which APs are located for WiFi-based indoor positioning systems. A data collection phase is followed by a data analysis phase. During data collection, measurement data to observed APs may be collected from various locations on different floors. The measurements data may include received signal strength indication (RSSI), optional round-trip-time (RTT) data to the APs, and floor information of the measurement locations. Measurement data may also be collected from crowd sourced data without floor information of the measurement locations. In data analysis, the collected measurement data are analyzed using various algorithms to determine if APs belong to the same floor and to assign APs on the same floor to the same cluster. APs on different floors may thus be assigned to different clusters. If the floor information of the measurement locations is known, each cluster may be assigned a floor number.
