Abstract
(EN)
An embodiment relates to a method for operating a terminal in a wireless communication system, the method comprising the steps of: transmitting, by a first terminal, a sidelink signal to a second terminal; and detecting, by the first terminal, a radio link failure (RLF) on the basis of either receiving a NACK for the sidelink signal as many times as N times (N is a positive integer) or non-receiving feedback related to the sidelink signal as many times as N times, wherein different weights (weighting factors) are added to the receiving of the NACK as many times as N times and the non-receiving of the feedback as many times as N times, respectively.
(FR)
Un mode de réalisation concerne un procédé pour faire fonctionner un terminal dans un système de communication sans fil, le procédé comprenant les étapes consistant à: transmettre, par un premier terminal, un signal de liaison latérale à un second terminal; et détecter, par le premier terminal, une défaillance de liaison radio (RLF) sur la base soit de la réception d'un NACK pour le signal de liaison latérale autant de fois que N fois (N est un nombre entier positif) ou soit d'une rétroaction de non réception liée au signal de liaison latérale autant de fois que N fois, des poids différents (facteurs de pondération) étant ajoutés à la réception du NACK autant de fois que N fois et la non réception de la rétroaction autant de fois que N fois, respectivement.
