Abstract

Un método para realizar una adaptación de tasa de realimentación operativa cuantificada en un sistema de comunicación inalámbrica, que comprende: la obtención (S201) de una señal de referencia desde de un punto de acceso; la deducción (S202) de una indicación de rango, una indicación de selección de subconjuntos de libros de códigos y un índice de matriz de precodificación sobre la base de la señal de referencia obtenida, en donde la indicación de selección de subconjuntos de libros de códigos está relacionada con las propiedades estáticas o a largo plazo de un canal físico de propagación; el envío (S203) de un primer mensaje de realimentación operativa que transmite la indicación de rango y la indicación de selección de subconjuntos de libros de códigos y el envío de un segundo mensaje de realimentación operativa que transmite el índice de matriz de precodificación, al punto de acceso y la recepción (S204), desde el punto de acceso, de datos precodificados por una matriz deducida sobre la base de la indicación del rango, la indicación de selección de subconjuntos de libros de códigos y el índice de matriz de precodificación.
