Abstract

La présente invention concerne un procédé et un dispositif de transmission de données permettant de résoudre le problème de la façon dont exécuter une transmission de données de processus HARQ après la survenue d'une activation, d'une désactivation ou d'un message RRC du groupe d'autorisations de configuration. La présente invention comprend : un terminal détermine de configurer de multiples groupes d'autorisations de configuration ; et le terminal traite des données à transmettre après avoir reçu un message de notification de mise à jour des groupes d'autorisations de configuration. Après avoir déterminé de configurer de multiples groupes d'autorisations de configuration, le terminal détermine un groupe d'autorisations de configuration qui doit être mis à jour lorsqu'un message de notification de mise à jour des groupes d'autorisations de configuration est reçu, et traite la transmission de données de processus HARQ dans le groupe d'autorisations de configuration qui doit être mis à jour. Après avoir reçu le message de notification de mise à jour du groupe d'autorisations de configuration, le terminal clarifie la façon dont traiter la transmission de données de processus HARQ dans le groupe d'autorisations de configuration qui doit être mis à jour.
