Beschreibung
Zusammenfassung:	A method and apparatus for detecting, by a first device, a timing measurement frame from a second device, the timing measurement frame having a plurality of time measurement samples, wherein at least the first of the measurement samples has a transmit timestamp value; determining transmit timing values for the subsequent measurement samples; applying a receive timestamp value to each of the received measurement samples; and determining a relative clock drift between a clock of the first device and a clock of the second device by comparing the receive timestamp values with transmit timing values of one or more measurement samples contained in the frame.
