Abstract

La presente descripción proporciona aparatos y métodos para establecer un acceso aleatorio. Los aparatos incluyen una terminal que comprende circuitos que, en funcionamiento, generan un primer preámbulo de acceso aleatorio; y un transmisor que, en funcionamiento, transmite el primer preámbulo de acceso aleatorio a una estación base en una primera ocasión (RO) del canal de acceso aleatorio físico (PRACH) entre una pluralidad de candidatos de RO, determinándose la pluralidad de candidatos de RO en base a la información de configuración de PRACH recibida desde la estación base, en donde la primera RO es asignada dentro de una primera región de frecuencia, siendo la primera región de frecuencia igual a una primera sub-banda en la que se realiza un procedimiento de escuchar antes de hablar (LBT) en la terminal.
