Abstract

Se divulgan un método, dispositivo inalámbrico y nodo de red para la retroalimentación de CSI con múltiples hipótesis de interferencia. De acuerdo con un aspecto, un método implementado en un dispositivo inalámbrico(WD) incluye recibir una configuración para la medición de la información de estado de canal (CSI) que incluye un primer conjunto de recursos de señal de referencia de la información de estado de canal, de potencia no cero, (NZP CSI-RS), para la medición de canal y un segundo conjunto de recursos de NZP CSI-RS para la medición de interferencia, el primer conjunto de recursos de NZP CSI-RS que tiene solo un recurso de NZP CSI-RS. El método también incluye medir la CSI con base en los primer y segundo conjuntos de recursos de NZP CSI-RS.
