Abstract

Métodos y aparatos para la retroalimentación de información de estado de canal (CSI) en una red inalámbrica. En una modalidad, un método incluye recibir señalización que incluya una primera configuración de señal de referencia (RS) de CSI de potencia distinta de cero (NZP) para la medición de canal; una segunda configuración de NZP CSI-RS; y una configuración de medición de interferencia de CSI (CST-TM) para la medición de interferencia. El método incluye recibir una solicitud de retroalimentación de CSI y estimar la CSI con base en al menos la primera configuración de NZP CSI-RS, la segunda configuración de NZP CSI-RS y la configuración de CSI-IM señalizadas.
