Abstract

Se proporciona un método para permitir a un equipo de usuario efectuar un procedimiento de acceso aleatorio en un sistema de comunicación inalámbrico. El método incluye la transmisión de un preámbulo de acceso aleatorio y la recepción de una respuesta de acceso aleatorio como respuesta al preámbulo de acceso aleatorio. La respuesta de acceso aleatorio está dirigida por un identificador de acceso aleatorio. El identificador de acceso aleatorio está mapeado a recursos de audio utilizados para transmitir el preámbulo de acceso aleatorio. El equipo de usuario puede confirmar inmediatamente su respuesta de acceso aleatorio y efectuar un procedimiento de acceso aleatorio eficiente adicional.
