Abstract

Se describen sistemas y metodologías que facilitan definir y utilizar patrones de salto para transmitir señales piloto de banda ancha en una red de comunicaciones inalámbrica. Las porciones de la amplitud de banda se pueden dedicar a transmitir los datos piloto de banda ancha, y los patrones se pueden utilizar para saltar a través de las frecuencias en periodos de tiempo dados para utilizar efectivamente la amplitud de banda dedicada entera. Además, la periodicidad para transmitir los datos se configura para permitir que los dispositivos que requieren programación adicional (por ejemplo, dispositivos de alta actividad) transmitan los datos piloto de banda ancha más frecuentemente. Los patrones de salto también pueden saltar a través de cambios cíclicos de los patrones para proporcionar diversidad óptima para transmitir las señales piloto de banda ancha.
