Abstract

Se proporciona una configuración de señal de referencia de enlace descendente adecuada para el incremento en el número de las capas de transmisión. Un dispositivo de estación de base inalámbrico (20) comprende una pluralidad de antenas de transmisión; una sección de generación de secuencia RS ortogonal (22) que genera una señal de referencia ortogonal de manera que las señales de referencia de enlace descendente en las mismas capas de transmisión son ortogonalizadas, estas capas se encuentran adyacentes entre sí en cada una de las direcciones de dos dimensiones de la dirección de frecuencia y la dirección de tiempo, y las señales de referencia de enlace descendente en diferentes capas de transmisión son ortogonalizadas, estas capas son asignadas a los mismos recursos inalámbricos, en función del código ortogonal de dos dimensiones, una sección de multiplexión (23) que multiplexa la señal de referencia de enlace descendente ortogonal con los datos de transmisión en la misma capa de transmisión, y una sección de transmisión que envía, de manera simultánea, una señal de transmisión obtenida multiplexando la señal de referencia de enlace descendente ortogonal con los datos de transmisión en la sección de multiplexión (23) a partir de la pluralidad de antenas de transmisión en una pluralidad de capas de transmisión.
