Abstract
A first wireless communication device includes a timing module to provide a timing synchronization function (TSF) time. A fine timing measurement module is to transmit a first request to perform a fine timing measurement to determine a distance between the first wireless communication device and a second wireless communication device. The first request includes a first value of the TSF time at which to start a burst period of the fine timing measurement, and the first value is determined in accordance with the TSF time provided by the timing module. The fine timing measurement module is further to receive a first response as transmitted from the second wireless communication device in response to the first request and transmit a second request to start the burst period at a TSF time indicated by the first value. The first response includes the first value of the TSF time.
