1. A method for receiving signal transmitted in a radio telecommunications network, said method comprising the following steps executed in a receiving unit:

  • receiving a radio signal carrying a common pilot channel (CPICH) and another channel (PICH), said common pilot channel carrying out a predefined reference signal and said other channel carrying state information;

    obtaining, from the radio signal, a first signal by channel estimation on the common pilot channel as a function of a code used on said common pilot channel and predefined reference signal transmitted on said common pilot channel; and

    a second signal by correlation of the received radio signal with a reference code;

    obtaining a resulting signal by complex conjugate multiplication of the first signal with the second signal; and

    determining a value for the state information indicated in the second signal on the basis of the resulting signal.
