Abstract
A first communication device generates a range measurement packet (or a packet that includes a probe response frame, a TIM frame, etc.) associated with a range measurement signal exchange session between the first communication device and a second communication device. The first communication device records a time value of a first timer corresponding to a time of transmission of the packet, and includes timing information corresponding to the recorded time value in the packet. The first communication device transmits the packet to the second communication device. The timing information in the packet is useable by a third communication device to adjust time values corresponding to a second timer, which the third communication device includes.
