Abstract

El presente revela un método y un equipamiento de usuario de realimentar información de canal a celdas coordinadas, un método y estación base de transmitir datos a un equipamiento de usuario en celdas coordinadas, y un método y sistema de comunicaciones inalámbricas. El método de realimentar información de canal a celdas coordinadas incluye: medir calidad de canal de canales de descarga de datos entre las celdas coordinadas y un equipamiento de usuario; clasificar las celdas coordinadas en diferentes clases de celda coordinada en base a un resultado de medición de la calidad de canal; seleccionar, en base a diferentes intervalos de calidad de canal correspondientes a las diferentes clases de celda coordinada, modos de realimentación de información con diferentes niveles de mejoramiento de realimentación para las diferentes clases de celda coordinada, respectivamente; y determinar información de canal a ser realimentada a celdas coordinadas en respectivas clases de celda coordinada en un orden predeterminado con uso de los modos de realimentación de información de canal seleccionados con diferentes niveles de mejoramiento de realimentación, y transmitir la información de canal determinada a las celdas coordinadas.
