Title:

FINE TIMING MEASUREMENT (FTM) METHOD AND COMMUNICATION DEVICE

Document Type and Number:

WIPO Patent Application WO/2017/114381

Kind Code:

A1

Abstract:

A fine timing measurement (FTM) method and a communication device. The method comprises: receiving FTM request frames sent by at least two communication devices; and sending a first FTM measurement frame according to the FTM request frames, the first FTM measurement frame comprising a measurement parameter of each of the at least two communication devices and identifier information used for indicating each communication device, so that each communication device obtains a measurement parameter according to the identifier information. An FTM measurement frame is sent in a broadcasting manner, so as to replace sending of multiple FTM measurement frames in the prior art; in this way, the number of times of interactions in FTM measurement between response devices and multiple communication devices, and the multiple communication devices can be measured at the same time, thereby reducing the measurement time and improving the measurement efficiency.
