Abstract

Un método para llevar a cabo notificación de información de estado de canal (CSI) por una terminal en un sistema de comunicación inalámbrica. El método incluye: recibir información de control de enlace descendente (DCI) que active la notificación de CSI; recibir una señal de referencia de CSI (CSI-RS) para la notificación de CSI; y transmitir, a una estación base, CSI que se determine con base en la CSI-RS que se reciba. El tiempo mínimo requerido para la notificación de CSI se configura en función de (i) un primer tiempo mínimo requerido a partir de una última sincronización de la CSI-RS hasta una sincronización de transmisión de la notificación de CSI, y (ii) un segundo tiempo mínimo requerido entre una DCI que active la CSI-RS y una recepción de la CSI-RS.
