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 14):
A communications apparatus, comprising a sending module, a receiving module, a recording module, a random number generation module, a timing module, and a calculation module, wherein\n the receiving module is configured to receive a measurement frame sent by a responder; the random number generation module is configured to randomly generate a short interframe spacing within a specified fluctuation range of a nominal short interframe spacing, wherein the nominal short interframe spacing is a short interframe spacing agreed upon between the responder and the requester; the timing module is configured to wait for the short interframe spacing randomly generated by the random number generator, after the receiving module finishes receiving a last symbol of the measurement frame; the sending module is configured to: when the wait of the timing module ends, send, to the responder, an acknowledgement frame in response to the measurement frame; the recording module is configured to store a measurement result generated through time measurement performed by the communications apparatus with the responder, wherein the measurement result comprises time stamps t 1 , t 2 , t 3 , and t 4 , t 1  is a time at which the responder sends the measurement frame, t 2  is a time at which the requester receives the measurement frame, t 3  is a time at which the requester sends the acknowledgement frame in response to the measurement frame, and t 4  is a time at which the responder receives the acknowledgement frame; and the calculation module is configured to calculate a location of the communications apparatus based on measurement results that are obtained by the communications apparatus by separately performing time measurement with a plurality of responders and that are recorded by the recording module.
