Le procédé comprend les étapes suivantes : une station de base configure de multiples signalisations de ressources CSI-RS du côté de l'équipement d'utilisateur par une signalisation de couche supérieure spécifique à l'UE ou une signalisation de couche supérieure publique et transmet la signalisation de ressources CSI-RS à l'équipement d'utilisateur ; chaque signalisation de ressources CSI-RS comprenant au moins l'une des informations suivantes : une information d'indication concernant le nombre de ports d'antenne, un domaine temporel et une information de position du domaine fréquentiel, des informations de position de ressources CSI-RS dans une sous-trame, une information de période et de décalage de sous-trame de la sous-trame de ressources CSI-RS, une information de puissance de la ressource CSI-RS et des informations de largeur de bande occupée par les ressources CSI-RS ; la station de base génère un CSI-RS en fonction des multiples signalisations de ressources CSI-RS, et transmet les CSI-RS à l'équipement d'utilisateur sur la ressource de domaine fréquentiel et le domaine temporel correspondants, et reçoit les CSI ou la rétroaction de puissance de réception d'un signal de référence de la part de l'équipement d'utilisateur.
