Abstract

La présente invention concerne un procédé et un dispositif d'attribution de ressources, qui sont utilisés pour garantir que des ressources attribuées par un nœud d'attribution de ressources de communication directe puissent mettre en correspondance la technologie d'accès sans fil sélectionnée par chaque canal logique sur l'interface de communication directe de terminal, garantissant ainsi que des données de communication directe peuvent être transmises à l'aide d'une technologie d'accès sans fil raisonnable. Sur le côté terminal, le procédé d'attribution de ressources fourni par le mode de réalisation de la présente invention consiste à : déterminer un mode d'attribution de ressources d'interface de communication directe configuré par un nœud de gestion de mode d'attribution de ressources pour le terminal ; sur la base de la technologie d'accès sans fil utilisée par chaque canal logique de l'interface de communication directe, déterminer les groupes obtenus en divisant les canaux logiques de l'interface de communication directe ; selon le mode d'attribution de ressources, effectuer indépendamment le traitement correspondant d'attribution de ressources d'interface de communication directe pour chaque groupe.
