Abstract

L'invention concerne un procédé et un appareil de transmission de signal permettant de résoudre le problème d'un grand retard de transmission provoqué par un dispositif de réseau hôte existant qui communique avec un UE au moyen d'un dispositif de relais multi-niveaux. Selon l'invention, un premier nœud reçoit des premières informations envoyées par un nœud de commande, les premières informations étant utilisées pour déterminer une première ressource de domaine temporel au niveau de laquelle le premier nœud reçoit un premier signal ; le premier nœud reçoit le premier signal au niveau de la première ressource de domaine temporel, puis transmet le premier signal reçu à une seconde ressource de domaine temporel ; la seconde ressource de domaine temporel est déterminée en fonction des secondes informations ; le premier nœud est un dispositif de relais. En configurant raisonnablement la ressource de domaine temporel pour le dispositif de relais afin de recevoir et de transmettre le premier signal, le dispositif de relais peut être amené à transférer rapidement le premier signal reçu, ce qui permet de réduire le retard de transmission.
