Abstract

En la presente invención, un equipo de usuario transmite un preámbulo de canal de acceso aleatorio (RACH) y una estación base recibe el canal de RACH. La estación base establece el preámbulo de RACH de modo que el límite del preámbulo de RACH en un dominio de tiempo coincida con los límites de los símbolos OFDM en los que se establece el preámbulo de RACH. El equipo de usuario genera/transmite el preámbulo de RACH de modo que el límite del preámbulo de RACH en un dominio de tiempo coincida con los límites de los símbolos OFDM en los que se establece el preámbulo de RACH.
