Abstract

Un procedimiento de transmisión en un sistema de comunicación de múltiples antenas, que comprende: formar (412) una pluralidad de grupos de sub-bandas (110) con una pluralidad de sub-bandas (110), en donde cada uno de la pluralidad de grupos incluye un subconjunto diferente de la pluralidad de subbandas (110); asignar (414) cada una de una pluralidad de antenas (524a-524t) a uno diferente de la pluralidad de grupos; y transmitir (420) simultáneamente desde la pluralidad de antenas (524a-524t) utilizando la pluralidad de grupos de sub-bandas (110), produciéndose la transmisión desde cada antena (524a-524t) en el grupo de sub-bandas (110) asignadas a la antena ( 524a-524t), caracterizado por que para cada antena (524a- 524t), una potencia de transmisión utilizada para cada una de las sub-bandas (110) en el grupo asignado a la antena (524a-524t) se escala mayor que una potencia media obtenida mediante la distribución de potencia de transmisión total a lo largo de la pluralidad de sub-bandas (110).
