Abstract

Un método para sincronizar señales en una red inalámbrica utiliza un preámbulo en dos partes transmitido en el enlace descendente entre una estación de base y una estación móvil. El preámbulo incluye un piloto común a una pluralidad de estaciones base y un piloto dedicado único a la estación de base de transmisión. La estación móvil lleva a cabo la sincronización gruesa basada en el piloto común y la sincronización fina basada en el piloto dedicado. La estación móvil también identifica una o más celdas circundantes basada en todos piloto únicos en el piloto dedicado transmitido por las celdas circundantes.
