Abstract

El propósito de la presente invención es evitar la reducción en la utilización de los recursos inalámbricos, incluso si existe poca información de control de enlace descendente transmitida en un cierto sub-cuadro. Esta estación inalámbrica de base envía la información de control de enlace descendente a cada terminal de usuario, por medio del PDCCH expandido, que son multiplexados por división de frecuencia con el PDSCH, y comprende: una unidad de distribución que distribuye a cada terminal de usuario una pluralidad de conjuntos PDCCHs expandidos que incluye cada una de una pluralidad de pares de PRBs colocados para el uso del PDCCH expandido, de manera que al menos un conjunto PDCCHs expandidos se superpone con otra terminal de usuario; y una unidad de mapeo que selecciona un conjunto PDCCHs expandidos de la pluralidad de los conjuntos PDCCHs expandidos, de manera que el número mínimo de los conjuntos PDCCHs expandidos es utilizado para la transmisión de la información de control de enlace descendente, en un sub-cuadro prescrito, y mapea la información de control de enlace descendente al par de PRBs que constituyen el conjunto seleccionado de PDCCHs expandidos.
