Abstract
A method for updating a timing offset for stored events scheduled in an event generator in a radio communication system including at least one base station and a mobile device includes a first step of measuring a change in a previously stored timing offset between a reference clock in the mobile device and a channel clock transmitted by the at least one base station. A second step includes adding the timing change to the previously stored timing offset in the timing offset register. A third step includes updating the timing offset in the event generator without interrupting execution of the stored events, such that synchronization is reacquired between the mobile unit and the base station. As a result, timing offset updating occurs without stopping or resetting the event generator.
