Abstract

Un método (500) de precodificación de transmisiones desde un dispositivo primero (10) a un dispositivo segundo (14), comprendiendo dicho método: recibir (502) retroalimentación (20) de precodificador factorizado desde el dispositivo segundo (14), que indica por lo menos una de una matriz de precodificador de conversión recomendada y una matriz de precodificador de ajuste recomendada que representan conjuntamente una matriz de precodificador recomendada, que es una multiplicación matricial de las matrices de precodificador de conversión y de ajuste recomendadas, donde dicha matriz de precodificador de conversión recomendada limita el número de dimensiones de canal consideradas por dicha matriz de precodificador de ajuste recomendada, y dicha matriz de precodificador de ajuste recomendada adapta dicha matriz de precodificador recomendada a un canal eficaz que está definido en parte mediante dicha matriz de precodificador de conversión recomendada, determinar (504) una operación de precodificación basándose al menos en parte en la evaluación de dicha matriz de precodificador recomendada, transmitir (506) una señal precodificada (12) al dispositivo segundo (14), que está precodificada de acuerdo con dicha operación de precodificación; y caracterizado por: mantener uno o varios libros (22) de código como una tabla bidimensional (28) de matrices de precodificador, donde cada fila o columna de dicha tabla (28) corresponde a una en particular de una pluralidad de matrices (24) de precodificador de conversión y cada columna o fila de dicha tabla (28) corresponde a una en particular de una pluralidad de matrices (26) de precodificador de ajuste, y donde dicha retroalimentación (20) de precodificador factorizado comprende por lo menos uno de un valor de índice de fila y un valor de índice de columna, para identificar una en particular de dichas matrices de precodificador en dicha tabla (28) como dicha matriz de precodificador recomendada, y comprender además mantener uno o varios libros (22) de código de matrices (24) de precodificador de conversión y matrices (26) de precodificador de ajuste, y en el que cada matriz (24) de precodificador de conversión tiene dimensiones fila- columna de NT x k, donde el número de filas NT es igual al número de puertos (56) de antena de transmisión en el dispositivo primero (10) y el número de columnas k es igual a la dimensión de conversión, que es menor que el valor de NT, y donde dicha matriz de precodificador de ajuste recomendada tiene dimensiones k x r, donde r es un rango de transmisión utilizado por el dispositivo primero, donde NT, k y r están relacionados como NT >= k >=r para restringir de ese modo el número de dimensiones de canal considerado mediante dicha matriz de precodificador de ajuste recomendada.
