TECHNIQUES FOR REDUCING SCANS FOR INDOOR POSITION DETERMINATION
Techniques for determining the position of a mobile device using almanac data are provided as are techniques for providing almanac data to the mobile device from a location server. The almanac data can be provided to the mobile device based on coarse location information provided by the mobile device. The almanac data can include information Media Access Control (MAC) addresses of one or more wireless access points and most recently used channel identification. The almanac data can also be binned by location by the location server and a subset of the almanac data can be selected to be provided to the mobile device based on the coarse location of the mobile device and on positioning effectiveness criteria associated with the wireless access points included in the almanac data.
Reactive hybrid location determination method and apparatus
A method is described of using the mobile device so as to control the drain of power from the power source of the mobile device, the mobile device having at least two location determination techniques having respective power drain characteristics, the method includes selecting the location determination technique having a lower power drain characteristic the greater the determined distance of the mobile device from a predetermined location or area, and selecting the location determination technique having the greater power drain characteristic the smaller the determined distance of the mobile device from a predetermined location or area. The method thus uses the least accurate technique when furthest away and the most accurate technique when closer to a predetermined location or area.
METHODS AND SYSTEMS FOR ENHANCED ROUND TRIP TIME (RTT) EXCHANGE
Disclosed are systems, methods and devices for obtaining round trip time measurements for use in location based services. In particular implementations, a fine timing measurement request message wirelessly transmitted by a first transceiver device to a second transceiver device may permit additional processing features in computing or applying a signal round trip time measurement. Such a signal round trip time measurement may be used in positioning operations.

Systems and methods for improved geolocation in a low power wide area network
Systems and methods for improved geolocation in a network are disclosed. An end node may transmit a signal. The signal may be received by a plurality of computing devices. Receipt times of the signal at the plurality of computing devices may be used to determine a location of the end node.
POWER EFFICIENT USER TRACKING
A tracking approach for mobile devices is performed. Responsive to detecting, using a transceiver of the vehicle, a mobile device reaching a first distance from a vehicle, a designated UWB anchor of a plurality of UWB anchors of the vehicle is activated to perform time-of-flight (TOF) distance measurements between the vehicle and the mobile device. Responsive to the TOF distance measurements between the mobile device and the designated UWB anchor indicating the mobile device has reached a closer, second distance from the vehicle, the plurality of UWB anchors are activated to perform trilateration between the vehicle and the mobile device to identify a position of the mobile device. Based on the position, a subset of the UWB anchors of the vehicle are utilized to continue to perform the trilateration, and a remainder of the UWB anchors other than the subset of the UWB anchors are inhibited to save power.
RESOURCE-EFFICIENT WIRELESS RANGING AND LOCALIZATION TECHNIQUES
Techniques for improved localization and ranging with reduced resource consumption are provided. At a first time, first movement information for a client device is determined. Based on the first movement information, a first set of localization parameters is selected. One or more localization techniques are performed in accordance with the first set of localization parameters. At a second time, second movement information for the client device is determined. Based on the second movement information, a second set of localization parameters is selected. One or more localization techniques are performed in accordance with the second set of localization parameters.
CONTEXT-AWARE NAVIGATION
Aspects presented herein relate to methods and devices for wireless communication including an apparatus, e.g., a device or a server. The apparatus may obtain a set of device parameters for one or more route segments from a server, wherein the set of device parameters for the one or more route segments includes an indication of an operation of the device along each of the one or more route segments. Additionally, the apparatus may set one or more device parameters of the set of device parameters for the one or more route segments based on a proximity of the device to a corresponding route segment of the one or more route segments.
Real-time location and presence using a push-location client and server
A system for providing real-time always-on location is presented for maintaining the current location of a mobile device, while saving the battery by managing the GPS in a power-saving mode while the device is considered to be stationary. The system also provides a real-time location in an indoor environment where a GPS signal may not be available. Additionally, methods for driving detection are also presented.
STATUS CHANGE NOTIFICATIONS FOR POSITIONING
Aspects of the disclosure are directed to a network component (e.g., a wireless network component such as transmission reception point (TRP) or gNB, a server user equipment (UE) or anchor UE, etc.) that registers to a status change notification function associated with a set of parameters (e.g., signal synchronization block (SSB) status, beam status, etc.). One or more notifications are sent to a position estimation entity (e.g., location management function (LMF), a target UE or server UE or anchor UE, etc.) in response to a status change to one or more parameters. The position estimation entity may then take various actions based on the status change notification(s), such as modifying one or more positioning session parameters. Such aspects provide various technical advantages, such as more accurate UE position estimation, reduced position estimation latency, reduced power consumption at the UE or the network or both, and so on.
