Abstract
(EN)
One embodiment of the present invention provides a method for transmitting, by a receiving terminal, a feedback signal to a transmitting terminal in a wireless communication system, the method comprising the steps of: receiving, by the receiving terminal, a reference signal from the transmitting terminal; and transmitting, by the receiving terminal, the feedback signal for the reference signal to the transmitting terminal, wherein the feedback signal is transmitted on the basis of compensation for a phase change that occurs when the reference signal is received.
(FR)
Un mode de réalisation de la présente invention concerne un procédé permettant à un terminal de réception d'émettre un signal de rétroaction à destination d'un terminal d'émission dans un système de communication sans fil. Le procédé comprend les étapes au cours desquelles le terminal de réception reçoit un signal de référence provenant du terminal d'émission et émet le signal de rétroaction associé au signal de référence à destination du terminal d'émission. Le signal de rétroaction est émis sur la base d'une compensation relative à un changement de phase qui se produit lors de la réception du signal de référence.
