Abstract

Modalidades de la presente invención proporcionan un método para determinar un espacio de búsqueda de canal de control; el método incluye: determinar números de conjuntos del EPDCCH utilizados para transmisión del canal de control de enlace descendente físico mejorado EPDCCH; determinar, de acuerdo con los números de los conjuntos de EPDCCH desfases de ubicación de espacios de búsqueda correspondientes a los conjuntos de EPDCCH; y determinar, de acuerdo con los desfases de ubicación de los espacios de búsqueda correspondientes a los conjuntos de EPDCCH, los espacios de búsqueda correspondientes a los conjuntos de EPDCCH; al agrupar y numerar recursos de tiempo-frecuencia de los EPDCCHs, y determinar diferentes desfases de ubicación para diferentes espacios de búsqueda del EPDCCH de acuerdo con los números y diferentes identidades de celda o identificadores de UE, se puede reducir una probabilidad de conflicto del espacio de búsqueda del canal de control; de esta manera, los recursos de tiempo-frecuencia de los canales de control se pueden elevar al máximo en un caso de múltiples usuarios, y se puede mejorar la eficiencia de la comunicación.
