Abstract
Un metodo de comunicacion digital inalambrico para comunicarse entre una estacion base (12) y una pluralidad de terminales moviles del equipo del usuario (UEs 30) y emplea la modulacion adaptativa y la codificacion para lograr la utilizacion mejorada de recursos de radio y proporcionar velocidades optimas de datos para los servicios de los usuarios. Los bloques de datos de enlace descendente (DL) son recibidos por la estacion base que requiere mediciones de calidad de canal DL, de enlace descendente, unicamente de aquellas terminales moviles (30) con transmisiones de enlace descendente pendientes. Las UEs responden a la peticion por la medicion y el reporte de la calidad de canal DL a la estacion base, que asigna luego recursos tal que las UEJ haran el mejor uso de los recurso de radio. La estacion base le notifica a las UEs de la asignacion del canal fisico indicando la proporcion de modulacion/codificacion y lapsos de tiempo asignados, seguidos por la transmision de los bloques de datos de enlace descendente que son transmitidos a las UEs.
