Abstract

Les modes de réalisation de la présente invention concernent un procédé de transmission de données, un appareil de communication et un support de stockage. Dans le scénario d'une ressource à multiples CC et d'autres ressources de domaine fréquentiel, lorsqu'un dispositif terminal utilise la ressource d'autorisation de configuration sur l'une des ressources de domaine fréquentiel (par exemple une CC) pour envoyer des données de liaison montante, la ressource d'autorisation de configuration utilisée par le dispositif terminal pour envoyer les données de liaison montante peut être indiquée à un dispositif de réseau par l'intermédiaire d'UCI. De cette manière, lorsque le dispositif de réseau ne reçoit pas correctement les données de liaison montante envoyées par le dispositif terminal sur la ressource d'autorisation de configuration, le dispositif de réseau peut programmer le dispositif terminal de façon à retransmettre les données sur une ressource de domaine fréquentiel correspondant à la ressource d'autorisation de configuration en fonction des UCI. Ainsi la fiabilité de la transmission des données de liaison montante est-elle garantie et les surdébits des ressources de retransmission de données réduits.
