Abstract

Un sistema de comunicaciones móviles para transmitir datos unidifusión y datos difusión/multidifusión desde una estación base a una estación móvil, incluyendo la estación base: una unidad de selección de datos (1) para seleccionar datos unidifusión o datos difusión/multidifusión para transmisión en una trama secundaria; una unidad de selección de señal piloto (4) para seleccionar una señal piloto específica de célula según la selección de datos unidifusión o datos difusión/multidifusión por la unidad de selección de datos (1); y una unidad de control de fase (5) dispuesta para realizar control de fase de modo que 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 es 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; incluyendo el aparato de recepción: una unidad de recepción (20, 21) para recibir la señal de datos incluyendo la señal piloto específica de célula transmitida por la estación base; y una unidad de extracción (200, 210, 220) para extraer la señal piloto específica de célula de la señal de datos recibida.
