Abstract

Un método y un aparato para transmitir una trama de señal de comunicación inalámbrica, como una supertrama de OFDM. En particular, los métodos y aparatos descritos transmiten un primer símbolo y aparato en la trama de la señal, donde el símbolo sirve para comunicar información de temporización aproximada a un receptor. Un segundo piloto es transmitido posteriormente para comunicar información que incluye información de identificación de red relacionada con una red de área amplia. A continuación, es transmitida información aérea (OIS) relacionada con la red de área amplia y entonces es transmitido un tercer símbolo piloto para comunicar información que incluye información de identificación de red relacionada con una red de área local a un receptor. Transmitiendo el tercer símbolo piloto relacionado con la red de área local después de los OIS de área amplia, se le permite a un receptor adquirir temporización de información de red de área amplia y entonces adquirir posteriormente más actualización de información de red de área local más actualizada y utilizar más eficientemente los recursos de procesamiento.
