Abstract

La présente invention concerne un procédé pour fournir des retransmissions en liaison descendante à une station mobile dans un réseau de communication sans fil, le réseau de communication sans fil comprenant une station de base liée en communication avec une station relais transparente. Selon le procédé, la station de base reçoit une demande de retransmission à partir de la station mobile; ordonnance des ressources pour la retransmission; signalise des informations d'ordonnancement pour la retransmission à la station relais transparente par l'intermédiaire d'une liaison de commande. La station relais transparente reçoit les informations d'ordonnancement pour la retransmission sur la liaison de commande; et envoie la retransmission à la station mobile dans une sous-trame de retransmission sur une bande de fréquence de retransmission.
