Abstract

Se describe un aparato de estación base que es utilizado en un sistema de comunicación móvil que utiliza un esquema OFDM en un enlace descendente. El aparato de la estación base incluye: una unidad configurada para realizar la transformación inversa de Fourier sobre una señal en la cual es mapeada una primera señal y una segunda señal a los subportadores con diferente densidad de energía de transmisión y para generar una señal de transmisión; y una transmisión configurada para transmitir la señal de transmisión a un aparato de usuario. Un subportador (subportador prohibido) en el cual es prohibido el mapeo de la segunda señal, es determinado tal que la densidad de energía de transmisión de la segunda señal es mantenida constante entre una pluralidad de símbolos OFDM sin importar la primera señal es o no incluida en un símbolo OFDM que incluye la segunda señal. El subportador prohibido es determinado con base en un subportador al cual es mapeada la primera señal.
