Abstract

Un método de realización de informe de la información del estado de canal (CSI) por un terminal en un sistema de comunicación inalámbrica. El método incluye: recibir la información de control de enlace descendente (DCI) que activa el informe de la CSI; recibir una señal de referencia de CSI (CSI-RS) para el informe de la CSI; y transmitir, a una estación de base, CSI que se determina sobre la base de la CSI-RS que se recibe. Un tiempo requerido mínimo para el informe de la CSI se configura sobre la base de (i) un primer tiempo requerido mínimo de un último tiempo de la CSI-RS a un tiempo de transmisión del informe de la CSI, y (ii) un segundo tiempo requerido mínimo entre una DCI que activa la CSI-RS y una recepción de la CSI-RS.
