A radio communication method in which a mobile station receives signaling information transmitted by a base station via a shared control channel, detects a presence/absence of data addressed to the mobile station, demodulates a shared data channel when the data is present, and receives data transmitted by the base station. The method includes the steps of transmitting, from the base station to the mobile station, a synchronization request via the shared control channel and transmitting, at the mobile station, feedback information including channel quality information, as a response to the synchronization request, via a random access channel. The method also includes generating, at the base station, timing advance information when receiving the feedback information, and transmitting, from the base station to the mobile station, the timing advance information, and adjusting, at the mobile station, a transmission timing of uplink data based on the timing advance information. |
