Abstract

Un método, en un nodo de red de radio, comprende identificar, entre un libro de códigos predeterminado de palabras codificadas de matriz de precodificación, un subconjunto de palabras codificadas de matriz de precodificación que no deben ser informadas por el dispositivo inalámbrico (90) en la información de estado de canal, CSI, retroalimentación y transmisión, al dispositivo inalámbrico (90), un mapa de bits que identifica el subconjunto de palabras de código de matriz de precodificación que no deben ser informadas por el dispositivo inalámbrico (90); en donde cada bit en el mapa de bits corresponde a una sola combinación de un índice de primera dimensión ?'1 y un índice de segunda dimensión ?'2 de las posibles combinaciones del primer índice de dimensión ?'1 y el segundo índice de dimensión ?'2, y en donde el índice de primera dimensión ?'1 y el índice de segunda dimensión ?'2 identifican un haz bidimensional, el haz bidimensional estando definido por un vector de números complejos comprendidos dentro de al menos una de una palabra de código de columna de matriz de precodificación en el libro de códigos.
