1. An apparatus of a station device, the apparatus comprising processing circuitry coupled to storage, the processing circuitry configured to:
generate a request frame to transmit to a responder station device, the request frame indicative of a preferred time window for ranging measurements to be performed between the station device and a responder station device;
identify a response frame received from the responder station device prior to receiving from the responder station device a measurement frame associated with performing ranging measurements, wherein the response frame indicates that the responder station device will send the measurement frame during the preferred time window;
generate, based on the response frame, a frame to transmit to the responder station device, during the preferred time window, the frame indicating that the station device is available for the ranging measurements; and
identify, during the preferred time window, the measurement frame received from the responder station device based on the frame indicating that the station device is available for the ranging measurements, the measurement frame associated with performing the ranging measurements, wherein the ranging measurements are based on the measurement frame received from the responder station device.
