Abstract

La presente invención revela un método y un sistema para transmitir información de control de enlace descendente, en los, cuando una estación base no está configurada con un campo indicador de portadora, dicha estación base transmite un canal físico de control de enlace descendente que lleva la información de control de enlace descendente correspondiente sobre cada portadora componente de enlace descendente en un conjunto de portadoras de canal físico compartido de enlace descendente (PDSCH) de un equipo de usuario, y el equipo de usuario detecta la información de control de enlace descendente correspondiente sobre cada portadora componente de enlace descendente en el conjunto de portadoras de PDSCH configurado. Cuando una estación base está configurada con un campo indicador de portadora, dicha estación base transmite el canal físico de control de enlace descendente que lleva la información de control de enlace descendente correspondiente sobre cada portadora componente de enlace descendente en el conjunto de portadoras de canal físico de control de enlace descendente (PDCCH) configurado, y el equipo de usuario detecta la información de control de enlace descendente correspondiente sobre cada portadora componente de enlace descendente en el conjunto de portadoras de PDCCH. Los conjuntos de portadoras de PDSCH y PDCCH son configurados por la estación base. La presente invención puede evitar múltiples veces de detección ciega y puede implementar la transmisión y detección de información de control de enlace descendente multiportadora.
