    Abstract: A method and apparatus for initiating communications on a shared channel in a mobile communication system are provided. A user equipment transmits an uplink signal for requesting communications on the shared channel to a Node B, and waits for a delay duration without monitoring a downlink after transmitting the uplink signal.
