Abstract

La présente invention concerne un procédé et un dispositif de traitement de données. Lorsqu'il n'envoie pas d'informations de commande, un dispositif de réseau peut occuper des ressources réservées aux informations de commande, de façon à transmettre des données, ce qui permet d'augmenter le taux d'utilisation de ressources. Lorsque des informations de commande sont détectées, un dispositif terminal doit déduire des informations reçues sur des ressources qui ne sont pas utilisées pour transmettre les données. En tant que telle, lorsque des informations de commande sont détectées, le dispositif terminal peut déduire des données qui sont traitées avec précision par des ressources pour transmettre des informations de commande, ainsi, la précision des données traitées est assurée tandis que le taux d'utilisation de ressources est garanti, ce qui permet d'augmenter la qualité de transmission de données.
