Abstract

La présente divulgation concerne un procédé et un appareil de détermination de ressource, et un support de stockage. Le procédé consiste à : recevoir une première signalisation envoyée par un dispositif réseau, la première signalisation étant une signalisation spécifique au terminal, et la première signalisation transportant des informations d'indication de ressource de sous-bande ; et sur la base des informations d'indication de ressource de sous-bande, déterminer une ressource occupée par une sous-bande dans une fenêtre temporelle. Au moyen de la présente divulgation, des ressources de sous-bande peuvent être configurées de manière dynamique, ce qui augmente la flexibilité de la configuration de sous-bande, améliore les performances d'un système de duplex intégral, et obtient une disponibilité élevée.
