Title:
METHOD AND APPARATUS FOR MEASURING POSITION IN NR V2X
Document Type and Number:
WIPO Patent Application WO/2022/245188
Kind Code:
A1
Abstract:
A method by which a first device performs wireless communication, and an apparatus supporting same are presented. The method may comprise the steps of: selecting a synchronization reference; and acquiring synchronism on the basis of a synchronization signal received from the synchronization reference. For example: the first device can receive a first PRS from a second device; the first device can transmit a second PRS to a third device; the first device can transmit the second PRS to the second device and the third device at a time point at which a threshold is added from a first time point at which the first PRS is received; the first device can acquire information about the sum of a first distance between the first device and the second device and a second distance between the first device and the third device on the basis of the first time point, a second time point at which the second PRS is received by means of the second device, and a third time point at which the second PRS is received by means of the third device; and the first device can acquire information about the position of the first device on the basis of the information about the sum of the first distance and the second distance.
