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 1):
A time measurement-based positioning method, comprising:\n separately performing, by a requester, time measurement with a plurality of responders, and calculating a location of the requester based on a measurement result, wherein a measurement result obtained by the requester by performing time measurement with each responder comprises time stamps t 1 , t 2 , t 3 , and t 4 , t 1  is a time at which the responder sends a 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 an acknowledgement frame in response to the measurement frame, t 4  is a time at which 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 a short interframe spacing that is actually used by the requester and that is randomly generated by the requester within a specified fluctuation range of a nominal short interframe spacing, and the nominal short interframe spacing is a short interframe spacing agreed upon between the plurality of responders and the requester.
