SINGLE-SIDED ROUND TRIP TIME (RTT) LOCATION ESTIMATION

This disclosure provides methods, devices and systems for performing a single-sided ranging operation. In some implementations, a first device transmits a first frame to a wireless station (STA), and receives a second frame from the STA responsive to the first frame. The first device obtains information indicating a time period between transmission of the first frame and reception of the second frame by the first device, and obtains information indicating time delays associated with a plurality of second devices, where each of the time delays is between respective receptions of the first frame and the second frame by a respective one of the second devices. The first device obtains a position of the STA based on the time period, the time delays associated with the plurality of second devices, and signal propagation times between the first device and each of the plurality of second devices.
