Abstract

La presente invención se refiere a un método para recibir un canal de control de enlace descendente por medio de una terminal en un sistema de canal inalámbrico y un aparato para lo mismo. En particular, el método para recibir un canal de control de enlace descendente por medio de una terminal en un sistema de canal inalámbrico incluye las etapas de: dividir al menos un bloque de recursos asignado a la terminal en el número preestablecido de subconjuntos; seleccionar uno o más subconjuntos para la terminal a partir del al menos un bloque de recursos; establecer el conjunto de subconjuntos seleccionado como un espacio de búsqueda para la terminal; y realizar la decodificación ciega para el espacio de búsqueda para detectar el canal de control de enlace descendente, en donde el número preestablecido de subconjuntos se desmodulan respectivamente por las señales de referencia de desmodulación (DM-RS) definidas con diferentes puertos de antena en cada uno de los bloques de recursos.
