Abstract

Procedimiento para la sincronización de tiempo para una estación móvil (MS) de un sistema de comunicación por radio donde el sistema de comunicación por radio condiciona canales de frecuencia (FK) formados por divisiones de tiempo (ts) y por gamas de frecuencias (B) de banda ancha, en los que se transmiten al mismo tiempo informaciones de una o de varias comunicaciones entre estaciones móviles (MS) y una estación de base (BS), y donde las informaciones de diferentes comunicaciones pueden ser diferenciadas por medio de códigos de difusión, en el que - se acondiciona de forma repetida una canal de frecuencia (SCH) para la sincronización de tiempo para las estaciones móviles (MS) en la dirección descendente, - dentro del canal de frecuencia (SCH) se transmiten, adicionalmente a las informaciones de otras comunicaciones, varias formas de señales (f1, f1a) diferentes conocidas, - se determinan los instantes (t1) de la llegada de las formas de las señales (f1, f1a) por la estación móvil (MS) a sincronizar a partir de las señales recibidas, y - se utilizan los instantes (t1) y el tipo de las formas de las señales (f1, f1a) por la estación móvil (MS) para la sincronización de tiempo con respecto a la división de tiempo (ts) y los cuadros.
