METHOD FOR PERFORMING TIMING MEASUREMENT FOR LOCATION ESTIMATION OF AN ELECTRONIC DEVICE WITH AID OF ONE REQUEST SENT TO MULTIPLE PEER DEVICES, AND ASSOCIATED APPARATUS |
摘要 |
A method and apparatus for performing timing measurement for location estimation of an electronic device are provided, where the method includes the steps of: sending a pre-association broadcast request frame to trigger multiple responders in a wireless network system to initiate timing measurement; and performing timing measurement according to a plurality of timestamps, for determining a location of the electronic device, wherein for a specific responder of the responders, a first timestamp and a second timestamp within the plurality of timestamps respectively correspond to a time of departure (ToD) and a time of arrival (ToA) of a pre-association uni-cast response frame received from the specific responder, and a third timestamp and a fourth timestamp within the plurality of timestamps respectively correspond to a ToD and a ToA of an acknowledgement frame corresponding to the pre-association uni-cast response frame, the acknowledgement frame sent from the electronic device to the specific responder. |

1. A method for performing timing measurement for location estimation of an electronic device, the method being applied to the electronic device, the method comprising the steps of:
sending a pre-association broadcast request frame to trigger multiple responders in a wireless network system to initiate timing measurement; and performing timing measurement according to a plurality of timestamps, for determining a location of the electronic device, wherein a portion of the plurality of timestamps is obtained from the responders, wherein at least one timestamp is determined based on a pre-association uni-cast response frame received from one of the responders; wherein no actual association is established between the electronic device and any of the responders. |
