<p>A method of operating a radio communication apparatus (100), comprises receiving an access parameter transmitted intermittently by a radio station(200), storing a value of the latest received access parameter, and transmitting an access signal. It further comprises receiving a validity indicator transmitted by the radio station(200), and if the validity indicator has a first value, employing the stored value of the latest received access parameter to transmit the access signal, and if the validity indicator has a second value, waiting to receive the next random access parameter and employing the value of said next access parameter to transmit the access signal.</p> |
