WIPO Patent Application WO/2021/075884

A1

The present invention relates to a terminal-based positioning method and device and, the terminal-based positioning method performed by a terminal in a wireless communication system, according to one aspect, can comprise the steps of: measuring a time difference of arrival (TDoA) for each distributed antenna on the basis of signals received from an anchor node through a plurality of distributed antennas; setting the relative position for each distributed antenna on the basis of a reference point preset in correspondence with the terminal; and determining an absolute position, which is the position of the reference point, on the basis of the TDoA measured for each distributed antenna and the relative position set for each distributed antenna.
