Abstract

La présente invention concerne un procédé de communication qui combine une technologie de l'Internet des objets (IoT) et un système de communication 5G qui prend en charge une vitesse de transmission de données supérieure au-delà d'un système 4G ; et un système correspondant. La présente invention peut s'appliquer à des systèmes intelligents basés sur une technologie de communication 5G et une technologie de l'Internet des objets (IoT) (par exemple, des maisons intelligentes, des bâtiments intelligents, des villes intelligentes, des voitures intelligentes ou des voitures connectées, des soins de santé, une éducation numérique, le commerce de détail, des services de sécurité et de sûreté, etc.). Dans un environnement prenant en charge à la fois un cas dans lequel une station de base attribue une attribution de planification (SA) et des ressources de données associées et un cas dans lequel un terminal sélectionne une SA et des ressources de données associées dans une communication de dispositif à dispositif (D2D), la présente invention suggère un procédé pour prendre en charge de manière efficace une attribution de ressource de données des deux modes d'attribution de ressource tout en maintenant de manière constante une attribution de ressource SA indiquant un format de région. En tant que mode de réalisation pour le procédé, au moins une valeur particulière parmi des valeurs d'informations d'indication d'attribution de ressource SA peut indiquer qu'un terminal a sélectionné une SA et une ressource de données, ou qu'une ressource SA et une ressource de données ont été reliées indirectement selon une règle prédéterminée. Les valeurs d'informations d'indication d'attribution de ressource restantes autres que la valeur particulière peuvent indiquer qu'une station de base a attribué une SA et une ressource de données, ou peut indiquer directement la position d'une ressource de données. Selon un autre procédé, une région de ressource SA est séparée en au moins deux régions et, selon la région de ressource, parmi les régions de ressource, à laquelle appartient la ressource reçue et transmise par une SA, une interprétation des informations d'indication d'attribution de ressource d'une SA peut être appliquée différemment.
