Abstract
A first device receives information related to an absolute location of a positioning reference from the positioning reference; obtains a first PRS reception timing based on a positioning reference signal (PRS) received from the positioning reference; obtains a second PRS reception timing at which a second device receives the PRS from the positioning reference, based on a phase difference value between first RSs received on first subcarriers from the second device; obtains a third PRS reception timing at which a third device receives the PRS from the positioning reference, based on a phase difference value between second RSs received on second subcarriers from the third device; estimates a relative location of the positioning reference, based on the first PRS reception timing, the second PRS reception timing, and the third PRS reception timing; and obtains location information of the first device based on the absolute location and the relative location.
