Abstract

Con el propósito de adjudicar apropiadamente recursos de radio a la información de control de enlace descendente en el canal de control de enlace descendente mejorado, la presente invención proporciona un método de radiocomunicación en un sistema de radiocomunicación en el cual una estación de base de radio transmite información de control de enlace descendente a cada terminal del usuario por vía de un canal de control de enlace descendente mejorado que es multiplexado por división de frecuencia con un canal de datos compartido de enlace descendente, el método de radiocomunicación comprende los pasos que consiste en: por la estación de base de radio, generar la información de control de enlace descendente en una unidad de eCCE, el eCCE está constituido por una pluralidad eREGs; y mapear la información de control de enlace descendente en una unidad eREG con respecto a una pluralidad de regiones de recursos para el canal de control de enlace descendente mejorado. Cada eREG está constituido por una pluralidad de REs y la estación de base de radio realiza el mapeo con respecto a cada una de las regiones de recursos de tal manera que los grupos de elementos de recursos mejorados (eREG5) sean uniformes en el número de elementos de recursos (REs) y los REs que constituyen 1 eREG se distribuyan a una pluralidad de símbolos de OFDM.
