Abstract

Se proporcionan nodos de red de radio, dispositivos inalámbricos y métodos relacionados en los que un valor de inicialización de secuencia pseudoaleatoria, que se usa durante la generación de secuencias pseudoaleatorias y/o aleatorizadas, se basa, al menos en parte, en un primer identificador, en donde el primer identificador es igual a un primer parámetro si el primer parámetro ha sido configurado y si un segundo identificador corresponde a un identificador específico de dispositivo inalámbrico.
