Abstract

Se divulga un aparato y un método para generar un libro de codigos de evolucion a largo plazo (LTE) y realizar una sustitucion de rangos. Se presentan reglas de reordenamiento, a través de las cuales un segundo vector de columna de cada matriz de precodificacion de rango 4 no aparecerá en los vectores de columna de una matriz de precodificacion de rango 3 y el primer vector de columna de cada matriz de precodificacion de rango 4 es idéntico al primer vector de columna de la matriz de precodificacion de rango 3 correspondiente. Además, se implementa el salto de precodificador entre dos matrices de precodificacion correspondientes a un índice de matriz de precodificacion (PMI) particular, a través de lo cual una primera de las dos matrices de precodificacion comprende un primer subconjunto de vectores de columna de una matriz de precodificacion original que corresponde al PMI particular, y una segunda de las dos matrices de precodificacion comprende un segundo subconjunto de vectores de columna de la matriz de precodificacion original. El salto de precodificador se realiza en el dominio de tiempo y/o frecuencia.
