Abstract

Se revela una estructura de marcos de canal físico comun de enlace ascendente (canal de acceso aleatorio) con una porcion de preámbulo y una porcion dedatos separaradas. La estacion de base usa el preámbulo para detectar que una estacion movil estái ntentando una solicitud de acceso aleatorio. La porcion dedatos del canal incluye los datos de usuario y los símbolos de piloto que proporcionan la energía para efectuar la estimacion de canal durante la recepcion dela porcion de datos. Se insertapr eferentemente un intervalo de proteccion (Tg) entre la porcion de preámbulo y la porcion de datos del marco, que permite quela deteccion de los datos se produzca durante un período inactivo en espera. De modo que resultan compatibles lasestructuras de marcos tanto para el canal deenlace ascendente físico comun (de acceso aleatorio) como para el canal de enlace ascendente físico dedicado (de tráfico).
