Abstract

Una estación base que controla adecuadamente retransmisión en bandas libres de licencia. En la estación base (100), una unidad de transmisión (107) envía información de control que pertenece a solicitudes de retransmisión para señales de respuesta para datos de enlace descendente y una unidad de recepción (108) recibe señales de respuesta que han sido retransmitidas sobre la base de la información de control. La información de control identifica uno entre una pluralidad de valores candidato que pertenecen al número de señales de respuesta solicitadas para retransmisión. La pluralidad de valores candidato se establecen sobre la base de cualquiera de una pluralidad de tamaños de grano.
