Abstract

La présente invention se rapporte au domaine des communications sans fil. L'invention divulgue un procédé et un appareil de configuration de cible secondaire, ainsi qu'un dispositif et un support d'enregistrement. Le procédé consiste à : recevoir, par un terminal, des informations de configuration envoyées par un nœud maître (MN), les informations de configuration comprenant une configuration de gestion d'une cible secondaire, et des informations temporelles correspondant à la configuration de gestion. Selon la solution technique des modes de réalisation de la présente demande, l'ajout d'un ou de plusieurs éléments d'informations temporelles correspondant à la configuration de gestion de la cible secondaire (SN et/ou SCG) permet au terminal d'obtenir des informations temporelles permettant d'exécuter une opération de gestion de la cible secondaire, de sorte que le terminal exécute de manière autonome, à un instant correspondant au temps d'arrivée d'informations, l'opération de gestion de la cible secondaire sans avoir besoin d'une utilisation fréquente d'une signalisation dédiée RRC, ce qui permet d'améliorer l'efficacité de configuration d'exécution de l'opération de gestion sur la cible secondaire. L'invention permet par conséquent de réduire le surdébit de signalisation, d'améliorer l'efficacité d'utilisation de ressources, et de réduire la perte d'un débit de transmission d'un terminal.
