Title:
METHOD AND DEVICE FOR ESTIMATING LOCATION BY USING ULTRA-WIDEBAND COMMUNICATION SIGNAL
Document Type and Number:
WIPO Patent Application WO/2024/076145
Kind Code:
A1
Abstract:
The present disclosure provides a method by which an electronic device determines the location of an ultra-wideband (UWB) signal. The method of the present disclosure may comprise the steps of: identifying, on the basis of a line of sight (LOS) probability for multiple received UWB signals, a preconfigured number of UWB signals from the multiple received UWB signals; obtaining the location of the electronic device by using the identified UWB signals; determining whether the obtained location is within an area of a cluster configured by UWB anchors transmitting the identified UWB signals; and determining, if the obtained location is within the area of the cluster, the obtained location as the final location of the electronic device. Here, each of the multiple received UWB signals may include a UWB message for downlink-time difference of arrival (DL-TDoA) positioning.
