Abstract

Dans ses modes de réalisation, la présente invention concerne un procédé d'attribution de ressources. Le procédé comprend les étapes suivantes : un terminal reçoit des informations d'attribution de blocs de ressources envoyées par un appareil de réseau, les informations d'attribution de blocs de ressources étant utilisées pour indiquer une ressource attribuée au terminal par l'appareil de réseau, la ressource attribuée au terminal par l'appareil de réseau étant sélectionnée par l'appareil de réseau parmi des ressources sélectionnables, et les ressources sélectionnables étant des ressources restantes après que des ressources non sélectionnables ont été supprimées de la totalité des ressources ; le terminal détermine, d'après les informations d'attribution de blocs de ressources, une première ressource attribuée par l'appareil de réseau ; et le terminal transmet ou reçoit des informations sur la première ressource. La présente invention est avantageuse en ce qu'elle répond à des exigences d'attribution de ressources et qu'elle utilise efficacement des bits d'informations d'attribution de blocs de ressources.
