Abstract

Un método ejecutado por un nodo de red en un sistema de comunicaciones incluye determinar una restricción de subconjunto de libro de códigos que indica un conjunto reducido de matrices de precodificación tomado de un conjunto original de matrices de precodificación de un libro de código original. El conjunto completo de bits del indicador de matriz de precodificación, PMI, se usa para identificar el conjunto original de matrices de precodificación del libro de códigos original. El método incluye determinar un conjunto reducido de bits del indicador de matriz de precodificación, PMI, para usarlo en un canal de realimentación en base a una cantidad de entradas en el conjunto reducido de matrices de precodificación. EI conjunto reducido de bits PMI tiene menos bits que el conjunto completo de bits PMI. Se divulgan equipos de usuario, métodos ejecutados por equipos de usuario y nodos de red relacionados.
