Abstract

Las modalidades de la descripción se refieren a un método para la detección ciega de un PDCCH y un dispositivo terminal; el método incluye: cuando el número de detecciones ciegas de PDCCH en al menos un espacio de búsqueda de un dispositivo terminal es mayor que un número máximo de detecciones ciegas, el dispositivo terminal reduce el número de detecciones ciegas de PDCCH en n espacios de búsqueda específicos de UE y/o m espacios de búsqueda comunes en el al menos un espacio de búsqueda, siendo el número reducido de detecciones ciegas de PDCCH menor o igual que el número máximo de detecciones ciegas; y el dispositivo terminal realiza detección ciega de PDCCH en el al menos un espacio de búsqueda de acuerdo con el número reducido de detecciones ciegas de PDCCH; de acuerdo con el método y el dispositivo terminal, el dispositivo terminal puede asignar el número de detecciones ciegas de manera más razonable, y reducir la complejidad de la estimación del canal del dispositivo terminal.
