METHOD AND APPARATUS FOR PERFORMING SIDELINK-BASED POSITIONING

Document Type and Number:

WIPO Patent Application WO/2021/141404

Kind Code:

A1

Abstract:

Provided are a method for performing, by a first device, wireless communication and an apparatus for supporting same. The method may comprise the steps of: receiving information related to an absolute location of a positioning reference from the positioning reference; obtaining a first PRS reception timing on the basis of a positioning reference signal (PRS) received from the positioning reference; obtaining, by a second device, a second PRS reception timing at which the PRS is received from the positioning reference on the basis of a phase difference value between first RSs received on first subcarriers from the second device; obtaining, by a third device, a third PRS reception timing at which the PRS is received from the positioning reference on the basis of a phase difference value between second RSs received on second subcarriers from the third device; estimating a relative location of the positioning reference on the basis of the first PRS reception timing, the second PRS reception timing, and the third PRS reception timing; and obtaining location information of the first device on the basis of the absolute location and the relative location.
