example 1

[0207] Example 1 includes a device that includes circuits and logic configured to trigger a mobile device to perform the following operations: receive deviation information from an access point (AP); perform a one-sided round trip time (RTT) measurement with the AP; And based on the one-sided RTT measurement and the deviation information, estimate the distance between the mobile device and the AP.

example 2

[0208] Example 2 includes the subject matter of Example 1, and is optionally configured to trigger the mobile device to send a request for receiving the deviation information, the request including an identifier of the AP.

example 3

[0209] Example 3 includes the subject matter of Example 1 or 2, and is optionally configured to trigger the mobile device to estimate the location of the mobile device based on the distance.

Abstract

The present disclosure relates to devices, systems and methods for one-sided round trip time (RTT) measurements. Some exemplary embodiments include apparatus, devices, systems and methods for one-sided round-trip time (RTT) measurement. For example, an apparatus may include circuitry and logic configured to cause a mobile device to: receive deviation information from an access point (AP); perform a one-sided round-trip time (RTT) measurement with the AP; and Measurements and deviation information estimate the distance between the mobile device and the AP.

Description

Technical field [0001] The embodiments described herein generally involve one-sided round trip time (RTT) measurement. Background technique [0002] Due to the development of various global navigation satellite systems (GNSS) (for example, Global Positioning System (GPS), GALILEO, etc.), outdoor navigation is widely deployed. [0003] Recently, people pay more attention to indoor navigation. This field is different from outdoor navigation because the indoor environment cannot receive signals from GNSS satellites. As a result, a lot of energy has been devoted to solving indoor navigation problems. [0004] There is no scalable solution with satisfactory accuracy for this problem. Summary of the invention [0005] According to one aspect of the present invention, there is provided a device including circuitry and logic, the device being configured to trigger a mobile device to perform the following operations: receive deviation information from an access point AP; perform unilateral ...
