Abstract

La presente invención se refiere a un procedimiento para procesa información dfe estado de canal (CSI), una estación base y un terminal. El procedimiento para procesar información de estado de canal incluye: una estación base que configura una pluralidad de procesos de CSI para una terminal, incluyendo cada proceso de CSI al menos información de una parte de medición de canal de información de una parte de medición de interferencia: cuando la estación base configura procesos de referencia de CSI correspondientes para procesos de CSI parciales a todos, al menos limitar un indicador de clasificación (RI) de los procesos o todos, al menos limitar un indicador de clasificación(RI) de los procesos de CSI para calcular un informe de CSI para que sea coherente con un RI de ,os procesos de referencia de CSI configurando los procesos de referencia de CSI; y para los procesos de CSI configurados con los procesos de referencia de CSI, recibiendo la estación base el informe de CSI de los procesos de CSI de acuerdo con el RI, o el RI y un PTI o el RI y un PM10 que corresponden a los procesos de referencia de CSI. Las realizaciones de la presente invención pueden realizar configuración y realimentación de información de estado de canal flexible. Reduciendo eficazmente de esta manera la tarea de realimentación de enlace ascendente y la posible probabilidad de colision de información de realimentación.
