Abstract

Los métodos y aparatos descritos en este documento permiten el uso de secuencias de señales de referencia de desmodulación, DMRS, que están numeradas en relación con un ancho de banda de sistema (30) global, mientras que al mismo tiempo permiten que los dispositivos de comunicación inalámbrica (12) determinen los elementos de secuencia DRMS asignados a sus anchos de banda programados (36) dentro del ancho de banda de sistema (30). En forma adecuada, los dispositivos de comunicación inalámbrica (12) no necesitan conocer el ancho de banda de sistema (30), o incluso ser conscientes de dónde residen sus anchos de banda programados (36) dentro del ancho de banda de sistema (30).
