    Abstract: Methods and systems are disclosed for improving reliability in mobile device positioning. A mobile device generates position data for a device, receives a first access point position reliability state associated with the first access point, determines a reliability of the position data based on the first access point position reliability state and an estimated location of the first access point, determines a threshold reliability requirement of an application associated with the mobile device, compares the reliability of the position data to the threshold reliability requirement of the application, and provides the position data of the device based on the comparison. A network entity determines access point characteristics associated with an access point, generates a position reliability state for the access point, sends the position reliability state to a mobile device, receives position data associated with the mobile device, and determines a trustworthiness of the position data.

    Abstract: Mobile devices implement a ranging mechanism that includes a lead responder receiving ranging measurement requests from two different initiators in the same DW cycle. At the beginning of the DW cycle the lead responder broadcasts and/or publishes a channel availability map that includes a list of slots and channels in which to respond to the ranging measurement requests based on a number of ranging operations supported in each slot within the DW cycle and based on an autonomously determined response sequence. If the lead responder responds to all ranging requests by all initiators in a DW cycle, secondary responders can perform ranging in the same or subsequent DW cycles. Upon exhausting all initiators paired with the lead responder, a secondary responder becomes the “active” responder that is chosen based on a prioritization scheme that is universal among the group of devices in the ranging operation.

    Abstract: A method of registering a target device includes: receiving a first indication to initiate a registration; and determining a suggested registration location and/or or a suggested registration name. The method further includes: providing a second indication of at least one of the suggested registration location or the suggested registration name; providing a third indication requesting at least one of whether the suggested registration location is accepted or whether the suggested registration name is accepted; receiving a fourth indication indicating at least one of whether the suggested registration location is accepted or whether the suggested registration name is accepted; and registering the target device by storing target device information based on the fourth indication.

    Abstract: Techniques for controlling transmit (Tx) power of an access point (AP) in a wireless communication system are described herein. An example of a method described herein includes detecting that a positioning exchange between an AP and a mobile device has been initialized; determining an estimated coverage area of the mobile device, an estimated Tx power level of the mobile device, and/or other operating parameters of the mobile device; and controlling a power level used by the AP for transmissions to the mobile device during the positioning exchange based on the determined operating parameters of the mobile device.
