Abstract

La présente invention concerne un procédé d'allocation de ressource et un appareil associé. Le procédé d'attribution de ressources comprend les étapes suivantes : un dispositif de réseau transmet des informations de commande de liaison descendante à un dispositif de terminal, X bits des informations de commande de liaison descendante étant utilisés pour indiquer des ressources de canal partagé de liaison montante physique (PUSCH); et le dispositif de réseau reçoit des données de liaison montante sur les ressources PUSCH, les ressources PUSCH indiquées par différentes valeurs binaires des X bits comprenant une ressource PUSCH d'un bloc de ressources physiques (PRB), une ressource PUSCH de deux PRB, et une ressource PUSCH de moins de 12 sous-porteuses. Le procédé d'attribution de ressources peut utiliser les différentes valeurs binaires de X bits dans une DCI pour indiquer une ressource PUSCH d'un PRB, une ressource PUSCH de deux PRB, et une ressource PUSCH de moins de 12 sous-porteuses, ce qui permet de réduire le surdébit de signalisation par rapport au scénario dans lequel des bits spécifiques sont requis dans des informations de commande de liaison descendante pour indiquer respectivement une attribution de ressources à l'aide de PRB et de sous-porteuses en tant qu'unités.
