Abstract

Se proporcionan nodos de red radioeléctrica, dispositivos inalámbricos y métodos relacionados en que un valor de inicialización de secuencia pseudo aleatoria usado durante la generación de secuencias pseudo aleatorias y/o de aleatorización se basa, al menos en parte, en un primer identificador, donde el primer identificador es igual a un primer parámetro, si éste se ha configurado y si un segundo identificador corresponde a un identificador específico de dispositivo inalámbrico.
