Abstract

Des modes de réalisation de la présente invention concernent un procédé de transmission de données et un dispositif de terminal. Le procédé comprend les étapes suivantes : un dispositif de terminal reçoit des informations d'indication de ressource d'autorisation de configuration qui sont envoyées par un dispositif de réseau et utilisées pour indiquer un ensemble de ressources d'autorisation de configuration configuré par le dispositif de réseau pour le dispositif de terminal, l'ensemble de ressources d'autorisation de configuration comprenant un processus HARQ cible ; si le dispositif de terminal reçoit des premières informations d'indication de ressource dynamique qui sont envoyées par le dispositif de réseau et utilisées pour indiquer une première ressource dynamique attribuée par le dispositif de réseau pour la HARQ cible du dispositif de terminal, le dispositif de terminal démarre un temporisateur d'autorisation de configuration ; si le dispositif terminal utilise une première ressource d'autorisation de configuration dans l'ensemble de ressources d'autorisation de configuration pour transmettre des données, le dispositif de terminal démarre un temporisateur de retransmission d'autorisation de configuration, le temporisateur de retransmission d'autorisation de configuration ne fonctionnant pas en même temps que le temporisateur d'autorisation de configuration. Le procédé de transmission de données et le dispositif de terminal dans les modes de réalisation de la présente invention améliorent l'efficacité de transmission de données.
