Abstract

Aparatos, métodos y sistemas se divulgan para la retroalimentación de parámetros para el libro de códigos basado en reciprocidad de tipo II. Un método (800) incluye recibir (805), desde una RAN, una configuración de libro de códigos correspondiente a un libro de códigos de selección de puertos y recibir (810) un conjunto de señales de referencia de CSI. El método (800) incluye identificar (815) un conjunto de puertos basados en las señales de referencia de CSI y generar (820) un conjunto de indicadores de coeficiente correspondientes al conjunto identificado de puertos, donde el libro de códigos de selección de puertos comprende un primer mapa de bits que identifica un subconjunto de los indicadores de coeficiente a los que se asigna un valor de amplitud distinto de cero. El método (800) incluye generar (825) un informe de CSI basado en el conjunto de señales de referencia de CSI y transmitir (830) el informe de CSI a la RAN, donde el primer mapa de bits se incluye selectivamente en el informe de CSI basado en un tamaño del subconjunto de indicadores de coeficiente.
