Abstract

En el caso de detectar la primera información utilizada para el primer acceso aleatorio y segunda información utilizada para el segundo acceso aleatorio, la segunda información siendo recibida desde la unidad de estación base (10), una terminal inalámbrica (20) selecciona una de entre la primera información y la segunda información (S1c); de esta manera, cualquiera de los accesos aleatorios puede ser realizado en forma selectiva, utilizando de manera eficiente los recursos tales como las signaturas utilizadas para el acceso aleatorio.
