Abstract

La présente invention concerne un système, une station de base, un terminal et un procédé de planification de ressource. Le procédé comprend les étapes consistant : à recevoir un rapport d'état de tampon de liaison latérale de terminal utilisateur à distance transmis par un terminal utilisateur à distance ; à ajouter des informations d'identification concernant le terminal utilisateur à distance dans le rapport d'état de tampon de liaison latérale de terminal utilisateur à distance ; à transmettre le rapport d'état de tampon de liaison latérale terminal utilisateur à distance ; à transférer, au terminal utilisateur à distance, une ressource de liaison latérale attribuée au terminal utilisateur à distance par la station de base selon rapport d'état de tampon de liaison latérale terminal utilisateur à distance. Ainsi, l'attribution d'une ressource de liaison latérale à un UE distant par un nœud b évolué (eNB) est réalisée par l'intermédiaire d'un équipement utilisateur (UE) relais, c'est-à-dire, une communication de dispositif à dispositif (D2D) entre des groupes d'UE à distance hors d'une plage de couverture de réseau est réalisée.
