Abstract

Según ciertas realizaciones, se divulga un método para usar en un dispositivo inalámbrico. El método comprende determinar si se restringe la transmisión de un preámbulo de acceso aleatorio durante al menos una parte de un conjunto de ráfagas de señal de sincronización (SS). El conjunto de ráfagas SS comprende al menos un bloque SS indicado como transmitido. En ciertas realizaciones, el método/dispositivo inalámbrico/código de programa informático además comprende transmitir el preámbulo de acceso aleatorio durante un tiempo en que la transmisión del preámbulo de acceso aleatorio no está restringida.
