Abstract

Se proporciona un dispositivo de radiocomunicación que puede suprimir interferencia entre códigos entre una señal ACK/NACK y una señal CQI que son multiplexadas por códigos. En este dispositivo, una unidad de difusión (214) difunde la señal ACK/NACK ingresada desde una unidad de juicio (208) al usar una secuencia de ZC. Una unidad de difusión (219) difunde la señal CQI usando una secuencia de ZC de desplazamiento cíclico. Usando una secuencia de Walsh, una unidad de difusión (216) difunde además la señal ACK/NACK que ha sido difundida usando la secuencia de ZC. Una unidad de control (209) controla la unidad de difusión (214), la unidad de difusión (216) y la unidad de difusión (219) de tal manera que el valor mínimo de la diferencia entre las señales CQI provenientes de una pluralidad de estaciones móviles y una cantidad de desplazamiento cíclico de la señal ACK/NACK no sea más pequeño que el valor mínimo de la diferencia entre las cantidades de desplazamiento cíclico en las señales ACK/NACK provenientes de la pluralidad de estaciones móviles.
