Abstract

Con el objetivo de prevenir el incremento en el número de detecciones ciegas y hacer uso eficiente de los recurso de radio aun cuando el formato de la información de control de enlace descendente cambia de acuerdo con el entorno de comunicación, la presente invención proporciona un método de comunicación de radio que genera la información de control utilizando un formato DCI predeterminado de entre una pluralidad de formatos DCI que incluye el primer formato DCI que contiene un otorgamiento de planeación de enlace ascendente y un segundo formato DCI que contiene una información de distribución de planeación de enlace descendente. Cuando el tamaño del primer formato DCI se expande, es agregado un campo de información al segundo formato DCI de tal modo que el segundo formato DCI tiene el mismo tamaño que el primer formato DCI expandido, y también la información que expande las funciones existentes del segundo formato DCI y/o la información que agrega nuevas funciones es agregada al campo de información, y es generada la información de control.
