Abstract

Se provee retroalimentación del estado del canal de un UE (800) a una estación de base (700) como un primer tipo detallado, o un segundo tipo menos detallado de información de retroalimentación del estado del canal. Inicialmente se determina (403) ya sea que UE haya recibido o no un traspaso de enlace ascendente de la estación de base. Si el UE ha recibido un traspaso de enlace ascendente, se transmite un primer tipo de información de retroalimentación del estado del canal (404) a la estación de base en el recurso traspasado. Sin embargo, si el UE no ha recibido un traspaso de enlace ascendente, un segundo tipo de información de retroalimentación del estado del canal se transmite (405) a la estación de base. Diferentes tipos de información de retroalimentación del estado del canal permite que un UE y una estación de base asociada use recursos disponibles más eficientemente, cuando se solicita y distribuye información de retroalimentación del estado del canal.
