Abstract
Un método para reportar la información de estado de canal de un equipo de usuario (UE) que tiene capacidades de cancelación de interferencias en un sistema de comunicación inalámbrica incluye recibir, desde una estación base de servicio, una configuración de reporte de estado de canal que indica un reporte de un estado del canal al que se aplica la cancelación de interferencia o un reporte de un estado canal al que no se aplica la cancelación de interferencia, el cálculo de un valor de reporte para un estado del canal de acuerdo con la configuración de reporte de estado del canal, y transmitir el valor de reporte para el estado del canal a la estación base de servicio. La configuración de reporte de estado de canal puede ser configurada por subconjunto de subtrama.
