Abstract
Un terminal de usuario (20) incluye un receptor (202) que recibe una señal de enlace descendente que comprende una señal de referencia de demodulación, un controlador (203) que separa la señal de referencia de demodulación de la señal de enlace descendente, y un estimador de canal (204) que calcula un valor de estimación de canal usando la señal de referencia de demodulación. El receptor (202) recibe información de asignación que indica un puerto asignado al terminal de usuario (20) entre una pluralidad de puertos, e información de patrón que indica un patrón de mapeo seleccionado de un primer patrón de mapeo que especifica un elemento de recurso en el cual la señal de referencia de demodulación se ordena en cada uno de la pluralidad de puertos y un segundo patrón de mapeo incluido en el primer patrón de mapeo, y el controlador (203) separa la señal de referencia de demodulación en el puerto asignado al terminal de usuario (20) de la señal de enlace descendente sobre la base del patrón de mapeo indicado por la información de patrón.
