Abstract

Se provee la retroalimentacion del estado de canal de un UE (800) a una estacion de base (700) como un primer tipo de informacion detallado o como un segundo tipo de informacion menos detallado de retroalimentacion del estado de canal. Inicialmente se determina (403) si el UE recibio o no un otorgamiento de enlace de carga desde la estacion de base. Si el UE recibio un otorgamiento de enlace de carga, un primer tipo de informacion de retroalimentacion del estado de canal es transmitido (404) a la estacion de base por el recurso otorgado. Sin embargo, si el UE no ha recibido un otorgamiento de enlace de carga, un segundo tipo de informacion de retroalimentacion del estado de canal es transmitido (405) a la estacion de base. Diferentes tipos de informacion de retroalimentacion del estado de canal permiten al UE y a una estacion de base asociada usar los recursos disponibles de manera más eficiente, cuando se solicite y provea informacion de retroalimentacion del estado de canal.
