Abstract: 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.

Abstract translation: 一些演示实施例包括基于精细定时测量（FTM）消息来确定时间同步功能（TSF）的设备，系统和/或方法。 例如，无线站可以被配置为在来自应答站的第一FTM消息到达时确定无线站的本地TSF的第一TSF值; 以确定来自所述响应者站的第二FTM消息到达时所述本地TSF的第二TSF值，所述第二FTM消息包括所述第一FTM消息的第一出发时间（TOD）值; 从所述响应者站处理第三FTM消息，所述第三FTM消息包括所述第二FTM消息的第二TOD值; 并且至少基于第一TSF值，第二TSF值，第一TOD值和第二TOD，向本地TSF应用TSF校正。
