Abstract
A synchronization control method in a communication system including a mobile station and a base station includes generating a synchronization request at the base station when data addressed to the mobile station arrives, receiving the synchronization request from the base station at the mobile station, transmitting feedback information at the mobile station as a response to the synchronization request, receiving the feedback information at the base station, generating timing advance information at the base station based on a reception timing of the feedback information, transmitting the timing advance information from the base station to the mobile station, and adjusting a transmission timing of uplink data at the mobile station, based on the timing advance information.
