Abstract

Le mode de réalisation de la présente invention concerne un procédé d'attribution de ressource et un dispositif et un support d'informations informatique. Le procédé peut comprendre les étapes consistant : à recevoir des informations de commande ; et à transmettre des données programmées par les informations de commande ; l'attribution de la partie de largeur de bande (BWP) correspondant aux données programmées par les informations de commande est déterminée au moyen de la relation de mappage entre les paramètres des informations de commande et l'attribution de BWP correspondant aux données programmées par les informations de commande. Il n'est pas nécessaire d'indiquer au moyen d'un domaine d'indication de DCI d'une façon d'afficher dans des DCI ; ainsi, la longueur du format de DCI est réduite et le BWP peut être attribué de manière dynamique.
