Abstract

La présente invention concerne un ordonnancement de ressources et un procédé, un dispositif et un système d'ordonnancement de coordination d'équipement d'utilisateur (UE). L'UE envoie un rapport de mesure ou un message de demande à un dispositif de réseau, le rapport de mesure comprenant des informations de qualité de canal entre des dispositifs de coordination adjacents à l'UE et l'UE, et le message de demande contenant des identificateurs des dispositifs de coordination adjacents à l'UE, de sorte que le dispositif de réseau sélectionne un ensemble de dispositifs de coordination parmi les dispositifs de coordination adjacents à l'UE pour participer à l'ordonnancement de coordination d'UE en fonction du rapport de mesure ou des identificateurs des dispositifs de coordination adjacents à l'UE, l'ensemble de dispositifs de coordination comprenant au moins deux dispositifs de coordination. L'UE reçoit une première indication envoyée par le dispositif de réseau, la première indication comprenant l'identificateur de chaque dispositif de coordination dans l'ensemble de dispositifs de coordination. L'UE effectue une communication de données avec le dispositif de coordination indiqué par l'identificateur de chaque dispositif de coordination dans l'ensemble de dispositifs de coordination. Un coût supplémentaire de spectre de fréquence radio peut ainsi être réduit et l'efficacité d'utilisation des ressources peut également être augmentée.
