Abstract

realizaciones para métodos de asignacion de banda ancha, detectar interferencia en otros sistemas, y/o re-desplegar en bandas anchas alternativas. Los canales de banda ancha mayores pueden ser desplegados en los límites (104) del canal, que son un subconjunto de aquellos para canales de banda ancha menores (310), y pueden estar restringidos para superponerse. Se puede detectar (930) interferencia en canales primarios, secundarios, o una combinacion de canales, y puede ser detectado en respuesta a mediciones de energía (910) de los diversos canales. Cuando se detecta interferencia, se puede reubicar un conjunto de servicio básico (BSS) de banda ancha mayor (100) en un canal alternativo, o puede reducir su banda ancha para evitar interferencia. La interferencia puede ser detectada basada en la energía medida en el canal primario o secundario y/o una diferencia entre los dos. Un FFT (1010) puede ser usado en la medicion de energía en uno o ambos de los canales primario y secundario. Las estaciones pueden también monitorear mensajes de sistemas alternativos para realizar decisiones de asignacion de canal. También se presentan diversos otros aspectos.
