Abstract:
A method includes: separately performing, by a requester, time measurement with a plurality of responders, and calculating a location of the requester based on a measurement result. A measurement result obtained by the requester by performing time measurement with each responder includes time stamps t1, t2, t3, and t4, where t1 is a time when the responder sends a measurement frame, t2 is a time at which the requester receives the measurement frame, t3 is a time when the requester sends an acknowledgement frame in response to the measurement frame, and t4 is a time when the responder receives the acknowledgement frame. The acknowledgement frame is sent by the requester after waiting for a randomly generated short interframe spacing after receiving a last symbol of the measurement frame. The randomly generated short interframe spacing is randomly generated within a specified fluctuation range of a nominal short interframe spacing.

Claim (Index 12):
The communications apparatus according to  claim 10 , wherein A2\u226410%*Delay\u22122*Distance/C, the distance represents a distance between the requester and the responder, C represents a speed of light, the delay is a fixed sum of delays that is defined at a physical layer, Delay=aCCATime+aRxTxTurnaroundTime+MACProcessingDelay, aCCATime is a clear channel assessment delay, aRxTxTurnaroundTime is a receive/transmit turnaround delay, and MACProcessingDelay is a MAC-layer processing delay.
