Abstract

En un sistema de comunicación de radio, una señal de medición de calidad de canal de recepción transmitida a partir de cada terminal de usuario es multiplexada mediante una FDMA de tipo de distribución que distribuye un bloque de frecuencia de tipo de distribución formado por subportadores de frecuencia distribuidos de manera discreta en un ancho de banda de sistema. El ancho de banda de sistema tiene una estructura de árbol binario. Cada banda de división es separada en dos. Una estación de base del sistema de comunicación de radio incluye: el medio que establece un ancho de banda de transmisión de una señal de medición de calidad de canal de recepción para la distribución a cada terminal de usuario de acuerdo con una pérdida de propagación entre la estación local y la terminal de usuario, esta pérdida ha sido reportada por cada terminal de usuario; medios que distribuyen una banda de división que corresponde con el ancho de banda de transmisión determinado entre los anchos de banda de división y que establece la frecuencia de transmisión; y medios que reportan el ancho de banda de transmisión y la frecuenta de transmisión.
