Abstract

Técnicas para transmitir de manera eficiente varios tipos de senalizacion sobre los enlaces directo e inverso en un sistema basado en OFDM. En lugar de atribuir específicamente subbandas a canales de senalizacion individuales, los datos de senalizacion para un canal de senalizacion en un enlace dado, son enviados como"subyacentes" a otras transmisiones que pueden ser enviadas sobre el mismo enlace. A cada terminal inalámbrica le es asignado un diferente codigo de PN. Los datos de senalizacion para cada terminal son distribuidos de manera espectral sobre la totalidad o sobre una porcion del ancho de banda del sistema utilizando el codigo de PN asignado. Para el enlace inverso, un terminal inalámbrico puede transmitir senalizacion sobre la totalidad de las N subbandas utilizables, y puede transmitir datos de tráfico sobre L subbandas asignadas para la transmision de datos, las cuales pueden ser un subconjunto de las N subbandas utilizables. Para el enlace directo, una estacion de base puede transmitir datos de senalizacion y de tráfico para la totalidad de los terminales en las N subbandas utilizables.
