Abstract

El dispositivo descrito hace posible levar a cabo eficientemente la transmisión de una primera señal de referencia y la transmisión de una segunda señal de referencia para estimación de canal sin deteriorar una precisión en la estimación de canal, y al mismo tiempo, llevar a cabo eficientemente la transmisión de la primera señal de referencia y la transmisión de la segunda señal de referencia para estimación de canal y la transmisión en un canal de control de enlace ascendente físico sin deteriorar una calidad de comunicación. Un aparato de estación móvil, en caso de que una transmisión de la primera señal de referencia y una transmisión de la segunda señal de referencia haya ocurrido que coinciden en la misma sincronización (Etapa S1O1, SÍ), lleva a cabo transmisión de la primera señal de referencia (Etapa S102), y en contraste, en caso de que una transmisión de la primera señal de referencia y una transmisión de la segunda señal de referencia haya ocurrido que coinciden en diferentes portadoras componentes en la misma sincronización (Etapa S1O1, NO), lleva a cabo una transmisión de la primera señal de referencia y una transmisión de la segunda señal de referenciá simultáneamente (Etapa S103).
