Abstract

Disclosed is a positioning method performed by a user equipment, the positioning method including receiving a first reference signal from a first transmitter and a second reference signal from a second transmitter, extracting a first sample vector based on received data of the first reference signal measured at a plurality of sample times and a second sample vector based on received data of the second reference signal measured at the plurality of sample times, calculating a first phase vector and a second phase vector by performing an inner product operation of a DFT coefficient vector for DFT operation with respect to each of the first and second sample vectors, and calculating a difference between a travel distance of the first reference signal and a travel distance of the second reference signal based on phase information of components included in a conjugate multiplication of the first and second phase vectors.
