Abstract

La presente invención se refiere a un sistema de radio comunicación que comprende una primera sección de medición de estado de línea de transmisión y una segunda sección de medición de estado de línea de transmisión, en donde cuando un segundo dispositivo de comunicación mide el estado de una línea de transmisión entre un primer dispositivo de comunicación y el segundo dispositivo de comunicación usando la señal de referencia del primer dispositivo de comunicación, la primera sección de medición de estado de línea de transmisión mide el estado del estado de línea de transmisión incluyendo la interferencia debido a la señal de otro primer dispositivo de comunicación, y la segunda sección de medición de estado de línea de transmisión mide el estado de la línea de transmisión entre el primer dispositivo de comunicación y el segundo dispositivo de comunicación mientras se suprime la interferencia debido a la señal del otro primer dispositivo de comunicación, por lo cual una información de retroalimentación apropiada se puede generar sin considerar cuando se realiza la comunicación cooperativa.
