Abstract

Se presenta un sistema y un método para atenuar la interferencia intercelular en sistemas EDM. El sistema permite un aumento en la eficiencia con los datos de la medición de carga generados por sub-banda tanto para las células servidoras como para las células vecinas que no son servidoras. El sistema permite compartir, con solidez, los datos de la medición de carga por sub-banda, tanto a través de un canal de retorno como directamente de la célula a la célula adyacente. Adicionalmente, un sistema de comunicación basado en el UE permite en el UE la reducción de los controles de carga asignados, basada directamente en la lectura de las mediciones de carga de las células vecinas. De este modo, el sistema maneja sólidamente varios tipos de célula (por ejemplo, sincrónica o asincrónica) y una variedad de facultades del UE al tiempo que permite aumentar la eficiencia en la gestión de la interferencia intercelular.
