Abstract

L'invention concerne un dispositif de configuration d'informations, un dispositif de déclenchement de rétroaction d'informations et un système de communication. Le dispositif de configuration d'informations comporte une unité de configuration. L'unité de configuration est utilisée pour configurer des informations associées à l'équipement utilisateur pour des informations d'état de canal (CSI) de rétroaction non-périodique. Les informations associées comprennent une relation de mappage entre les informations d'indication pour indiquer un rapport d'un ensemble CSI et un ensemble de processus CSI. Un processus CSI dans l'ensemble de processus CSI comprend au moins un des types suivants de processus CSI : un processus CSI dans une direction horizontale, un processus CSI dans une direction verticale, et un processus CSI joint dans un canal spatial tridimensionnel. Le dispositif de configuration d'informations, le dispositif de déclenchement de rétroaction d'informations et le système de communication permettent d'obtenir une flexibilité de rétroaction et de réduire le surdébit de signalisation en combinant une signalisation de couche plus élevée et des informations dynamiques.
