Abstract

Se divulgan aparatos, métodos, y sistemas para notificación de información de estado de canal. Un método (1000) incluye recibir (1002) información de configuración de notificación de información de estado de canal, en donde la información de configuración de notificación de información de estado de canal incluye: información que indica que una o más configuraciones de recursos de señal de referencia de información de estado de canal de información de estado de canal asociadas con un conjunto de recursos de señal de referencia de información de estado de canal de información de estado de canal para medición de canal y un conjunto de recursos de gestión de interferencia de información de estado de canal para medición de interferencia; e información que indica que se usa la retroalimentación de información de estado de canal que corresponde a múltiples puntos. El método (1000) incluye generar (1004) un conjunto de notificaciones de información de estado de canal con base en la información de configuración de notificación de información de estado de canal. Cada notificación de información de estado de canal en el conjunto de notificaciones de información de estado de canal incluye dos partes. El método (1000) incluye reportar (1006) el conjunto de notificaciones de información de estado de canal a la red.
