Abstract
(EN)
One embodiment relates to a method for measuring, by a first terminal, a distance between the first terminal and a second terminal and positions thereof in a wireless communication system, the method comprising the steps of: receiving, by a first terminal, a first signal and a second signal from a second terminal; and measuring, by the first terminal, a distance between the first terminal and the second terminal on the basis of the first signal and the second signal, wherein the distance is measured on the basis of a first transmitting angle, a second transmitting angle, a first receiving angle, a second receiving angle, and a difference between a first receiving time when the first terminal receives the first signal and a second receiving time when the first terminal receives the second signal.
(FR)
Un mode de réalisation de l'invention concerne un procédé de mesure, par un premier terminal, d'une distance entre le premier terminal et un second terminal et de positions de ce dernier dans un système de communication sans fil, le procédé comprenant : la réception, par un premier terminal, d'un premier signal et d'un second signal provenant d'un second terminal ; et la mesure, par le premier terminal, d'une distance entre le premier terminal et le second terminal en fonction du premier signal et du second signal, la distance étant mesurée en fonction d'un premier angle de transmission, d'un second angle de transmission, d'un premier angle de réception, d'un second angle de réception et d'une différence entre un premier instant de réception lorsque le premier terminal reçoit le premier signal et un second instant de réception lorsque le premier terminal reçoit le second signal.
