Abstract

La présente divulgation se rapporte à un procédé de détermination d'informations, ainsi qu'à un appareil et un support de stockage. Le procédé est exécuté par un terminal, et consiste à : recevoir de premières informations de configuration envoyées par un dispositif de réseau, les premières informations de configuration étant utilisées pour indiquer un premier coefficient et un second coefficient correspondant à une pluralité de ressources CSI-RS ; et déterminer le nombre de ports CSI-RS sur la base du premier coefficient et du second coefficient. Ainsi, un terminal peut déterminer le nombre de ports CSI-RS sur la base d'un premier coefficient et d'un second coefficient d'une pluralité de ressources CSI-RS configurées par un dispositif de réseau, et peut réaliser la configuration d'un plus grand nombre de ports CSI-RS, de façon à prendre en charge des mesures de canal avec le plus grand nombre de ports CSI-RS, ce qui permet d'améliorer les performances d'un système de communication.
