Abstract
Disclosed are systems, apparatuses, methods, and computer-readable media for identifying a location of a wireless device. A method for identifying a location of a wireless device includes transmitting a request message to the wireless device for identifying a position of the wireless device; receiving a response message from the wireless device; determining first time information based on a time of flight (ToF) of the request message and the response message, wherein the ToF corresponds to a distance of the wireless device from the AP; receiving a second message from a second AP that includes second time information associated with the request message and the response message; receiving a third message from a third AP that includes third time information associated with the request message and the response message; and transmitting location configuration information to the wireless device for the wireless device to determine a position of the wireless device.
