Abstract

Un sistema de comunicaciones móviles incluyendo una estación base y una estación móvil, en el que la estación base transmite datos unidifusión y datos difusión/multidifusión así como una señal piloto específica de célula a la estación móvil, incluyendo la estación móvil una unidad de recepción (20, 21) para recibir la señal piloto específica de célula transmitida desde la estación base; caracterizado porque la estación base incluye: una unidad de control de fase (5) para controlar el establecimiento de una diferencia entre una fase de inicio de una señal piloto específica de célula transmitida en una trama secundaria en la que la estación base transmitió los datos unidifusión y una fase de inicio de una señal piloto específica de célula a transmitir en una trama secundaria siguiente de modo que sea igual a una diferencia entre una fase de inicio de una señal piloto específica de célula transmitida en una trama secundaria en la que la estación base transmitió los datos difusión/multidifusión y una fase de inicio de una señal piloto específica de célula a transmitir en una trama secundaria siguiente.
