Abstract

La presente invención se refiere a un método en el cual una terminal realiza intercalado de canales en un sistema de comunicación inalámbrica de varias antenas. Más particularmente, el método comprende las siguientes etapas: construir información de indicador de calidad de canal (CQI) e información de datos codificados en vectores de ancho de bit preestablecidos para generar una primera secuencia de vector de entrada de intercalador; repetir la información de indicador de clasificación (Rl) y la información de confirmación/confirmación negativa (ACK/NACK) para el número (NL) de capas de transmisión para generar una segunda secuencia de vector de entrada de intercalador de vectores de ancho de bit preestablecido y una tercera secuencia de vector de entrada de intercalador de vectores de ancho de bit preestablecido; mapear la primera secuencia de vector de entrada de intercalador, la segunda secuencia de vector de entrada de intercalador y la tercera secuencia de vector de entrada de intercalador en una matriz de intercaladores, respectivamente; y leer la matriz de intercaladores en una base por columnas para generar una secuencia de vector de salida. El ancho de bit preestablecido se define por el producto de un orden de modulación (QPm) y el número (NL) de capas de transmisión.
