Abstract

La presente invención se refiere a un método, equipo de usuario y una estación base adaptada para manejar reportes de retroalimentación del estado de canal en una forma más flexible. Más específicamente, se proporciona un procedimiento para la retroalimentación del estado de canal que utiliza los recursos disponibles para la transmisión de retroalimentación del estado de canal de forma más eficiente. Esto se obtiene incluyendo la disponibilidad de la concesión del enlace ascendente hacia los activadores de reportes de retroalimentación del estado de canal utilizado para determinar cuando y como enviar la retroalimentación del estado de canal desde el UE, es decir, una solicitud de reporte de retroalimentación del estado de canal se puede enviar por medio de una estación base en una concesión de enlace ascendente a un UE que consiste en una indicación de una cantidad esperada de información que se va a regresar.
