Polled time-of-flight response

摘要

Embodiments of a communication station and method for time-of-flight (ToF) location determination in a wireless network are generally described herein. In some embodiments, a responding communication station receives a ToF measurement request. The responding communication station transmits an acknowledgment of the ToF measurement request. The responding communication station also transmits a response to the ToF measurement request that includes an indication of a time period for an initiating communication station to poll the responding communication station for a ToF result.

主权项

1. A method to be performed by a communication station for time-of-flight (ToF) calculation, the method comprising:
receiving a ToF measurement request/poll action frame from an initiating communication station at a first time, the ToF measurement request/poll action frame comprising a measurement request bit to indicate to perform a measurement; transmitting, to the initiating communication station, an acknowledgment of the ToF measurement request/poll action frame at a second time; transmitting, to the initiating communication station, a response to the ToF measurement request/poll action frame to request to perform the measurement, the response comprising an indication of a time period for the initiating communication station to poll a responding communication station for a ToF result; receiving, from the initiating communication station, a measurement request/poll action frame comprising a measurement poll bit to indicate to poll for the ToF result; and transmitting the ToF result to the initiating communication station.
