Abstract

Se divulgan un método, una estacion de base de red y un dispositivo de comunicaciones de usuario para transmitir datos en una portadora con multiplexion por division de frecuencia ortogonal. Un conjunto de antenas puede transmitir una senal decodificable por un dispositivo de comunicaciones de usuario heredado disenado para la compatibilidad con un conjunto heredado de antenas de transmision. Un procesador 210 puede codificar una subtrama de la senal con un conjunto heredado de símbolos de referencia comunes y un conjunto suplementario de símbolos de referencia comunes que se refiere al conjunto de antenas.
