LOCATION PROTOCOL WITH ADAPTIVE RANGING TRIGGER

This disclosure provides methods, devices, and systems for minimizing ranging errors resulting from clock drift and/or frequency offsets between wireless communication devices such as a responder device and an initiator device. In various implementations, the responder device receives a request for a ranging operation from the initiator device. The responder device determines whether its temperature exceeds a threshold. When the responder device's temperature exceeds the threshold, the responder device determines a time period after which the responder device's temperature is expected to decrease below the threshold. The responder device transmits a response frame indicating the responder device's temperature and the determined time period. In some instances, the determination that the responder device's temperature exceeds the threshold indicates that ranging errors resulting from clock drift and/or frequency offsets between the responder device and the initiator device are greater than an amount.
