Apparatus, system and method of determining a time synchronization function (TSF) based on fine time measurement (FTM) messages

摘要

Some demonstrative embodiments include apparatuses, systems and/or methods of determining a Time Synchronization Function (TSF) based on Fine Timing Measurement (FTM) messages. For example, a wireless station may be configured to determine a first TSF value of a local TSF of the wireless station at arrival of a first FTM message from a responder station; to determine a second TSF value of the local TSF at arrival of a second FTM message from the responder station, the second FTM message including a first Time of Departure (TOD) value of the first FTM message; to process a third FTM message from the responder station, the third FTM message including a second TOD value of the second FTM message; and to apply to the local TSF a TSF correction based at least on the first TSF value, the second TSF value, the first TOD value, and the second TOD.
