Abstract

La présente invention concerne un procédé, un appareil et un système de transmission de données qui, dans les modes de réalisation de la présente invention, relèvent du domaine technique des télécommunications. Le procédé consiste à informer chaque Equipement d'Utilisateur (UE) d'un groupe bidimensionnel d'informations de corrélation du groupe bidimensionnel, le groupe bidimensionnel contenant au moins deux UE et les informations de corrélation du groupe bidimensionnel étant appliquées de manière à indiquer la situation des ressources temps-fréquence du groupe bidimensionnel occupé par chaque UE ; à envoyer à chaque UE un Canal de Commande Physique Descendant, PDCCH, pour indiquer les ressources temps-fréquence du groupe bidimensionnel ; et à transmettre des données au moyen de chaque UE concernant les ressources temps-fréquence du groupe bidimensionnel occupé par chaque UE. En adoptant le mode de planification du groupe bidimensionnel et en subdivisant des ressources de Blocs de Ressources Physiques (PRB, Physical Resource Blocks) dans le domaine temporel et dans le domaine fréquentiel, la présente invention permet d'améliorer le taux d'utilisation des ressources dans des scénarios d'applications particulières et d'augmenter le nombre d'UE planifiés, cela permettant d'effectuer des économies en données de gestion PDCCH lorsqu'il est nécessaire de planifier des équipements à grande échelle.
