Abstract

La présente demande se rapporte au domaine technique des communications, et divulgue un procédé et un appareil de configuration de rapport d'informations d'état de canal (CSI), un terminal, et un dispositif côté réseau. Le procédé de configuration de rapport de CSI dans les modes de réalisation de la présente demande comprend les étapes suivantes : un terminal reçoit des premières informations d'indication, les premières informations d'indication étant utilisées pour indiquer des informations de configuration requises pour activer un rapport de CSI correspondant à un mode côté réseau qui est sur le point de prendre effet ; et le terminal détermine, sur la base des premières informations d'indication et des informations de configuration pré-configurées relatives à une pluralité d'ensembles de rapports de CSI, des informations de configuration cible correspondant au mode côté réseau qui est sur le point de prendre effet, les informations de configuration relatives à chaque ensemble de rapports de CSI étant des informations de configuration requises pour un rapport de CSI correspondant à un mode côté réseau.
