Abstract

Métodos y aparato para procesar y generar mensajes de radiodifusión determinados por una subbanda y los símbolos de marcos de OFDM en los que se reciben las señales. Se generan mensajes de sobrecarga que indican los recursos utilizados por los mensajes de radiodifusión en un sistema de comunicación inalámbrica. Se reciben señales a través de un sistema inalámbrico y a partir de estas señales se determinan mensajes de radiodifusión, según se designa por medio de una subbanda y de los símbolos de OFDM de los cuadros de un ultramarco en el que se reciben las señales.
