Abstract

Las modalidades de la presente invención proporcionan un método, dispositivo de red y equipo de usuario (UE) para el procesamiento de procesos de información de estado de canal, en donde el método para el procesamiento de procesos de información de estado de canal incluye: después de recibir una primera solicitud de información de estado del canal (CSI) enviada por un primer dispositivo de red, si la CSI correspondiente a múltiples procesos CSI aperiódicos no ha sido reportada por un equipo de usuario, descartar la CSI correspondiente a una parte de procesos CSI aperiódicos entre múltiples procesos CSI aperiódicos, en donde cada proceso CSI está asociado con un recurso de medición del canal y un recurso de medición de interferencia. Por lo tanto, el problema de que un UE no puede implementar el procesamiento de múltiples procesos de CSI, después de una tecnología CoMP, puede ser resuelto.
