Abstract

Un sistema de comunicaciones móviles para comunicar datos a, y/o desde dispositivos móviles de comunicaciones. El sistema de comunicaciones móviles incluye un transmisor y un receptor que pueden ser operados para proporcionar una interfaz inalámbrica de acceso para comunicar datos a, y/o desde los dispositivos móviles de comunicaciones, la interfaz inalámbrica de acceso que proporciona en un portador anfitrión, el portador anfitrión que proporciona una pluralidad de elementos de recursos a través de un primer rango de frecuencias para comunicar datos; y un primero y un segundo dispositivos móviles de comunicaciones. El primer dispositivo móvil de comunicaciones se puede operar para recibir las comunicaciones de enlace descendente vía el portador anfitrión. La interfaz inalámbrica de acceso proporcionada por la una o más estaciones base se arregla para proporcionar un portador virtual, el portador virtual que proporciona uno o más elementos de recursos dentro de un segundo rango de frecuencias el cual está dentro y es más pequeño que el primer rango de frecuencias y el segundo dispositivo móvil de comunicaciones se puede operar, tras la detección del portador virtual, para recibir comunicaciones de enlace descendente vía el portador virtual.
