Abstract

La presente invención se diseña para hacer posible una adjudicación de recursos de radio de enlace ascendente adecuados para la información de reconocimiento de suministro de un canal de datos compartido de enlace descendente cuando la información de control de enlace descendente se transmite utilizando un canal de control de enlace descendente mejorado. El sistema de radiocomunicación de acuerdo con la presente invención tiene los pasos en los cuales una estación de base de radio configura una pluralidad de conjuntos de PDCCH mejorados, los cuales se forman cada uno para incluir una pluralidad de elementos de canal de control mejorado (eCCEs) adjudicados al canal de control de enlace descendente mejorado, para una terminal del usuario, la estación de base de radio transmite, a la terminal del usuario, la información de control de enlace descendente, a la cual se agregan identificadores de recursos (ARIs), los identificadores de recursos son diferentes entre la pluralidad de conjuntos de PDCCH mejorados, y la terminal del usuario determina los recursos de radio para un canal de control de enlace ascendente que se utilizan para transmitir información de reconocimiento de suministro del canal de datos compartido de enlace descendente con base en valores de compensación que están asociados con los identificadores de recursos (ARIs).
