<p>A signal transmitted in a radio telecommunications network is received (41). This radio signal carries a common pilot channel and another channel, with said other channel carrying state information. Then one obtains (42), from the radio signal, a first signal by channel estimation on the common pilot channel and a second signal by correlation of the received radio signal with a reference code. Next, a resulting signal is obtained (43) by complex conjugate multiplication of the first signal with the second signal. Lastly, a value for the state information indicated in the second signal is determined (44) on the basis of the resulting signal.</p> |
