Abstract

Aún cuando la comunicación se realiza independientemente en cada CC (Portador de Componente), se previene la incidencia de un error de comunicación. Se proporciona un sistema de radio comunicación en el cual un dispositivo de radio-transmisión y un dispositivo de radio- recepción se comunican entre si usando una pluralidad de bandas de frecuencia de sistema, en donde el dispositivo de radio-transmisión realiza el control de potencia de transmisión en cada una de las bandas de frecuencia de sistema en datos de transmisión, y también puede realizar tal control que las potencias de transmisión máximas son diferentes entre las bandas de frecuencia de sistema respectivas. Las prioridades se establecen en las bandas de frecuencia de sistema respectivas, y las potencias de transmisión de las bandas de frecuencia de sistema se determinan en orden de la de más alta prioridad.
