Not only pilot channel symbols but also control channel symbols can be flexibly decreased in a radio communication system, which includes a transmission side apparatus transmitting a data frame where a plurality of continuous or discontinuous frequency areas are assigned to one transfer time block and a frame is formed of a predetermined number of transfer time blocks; and a reception side apparatus receiving a data frame from the transmission side apparatus, The transmission side apparatus transmits to the reception side apparatus a data frame which has a common pilot channel and a control channel in the beginning of the frame, the reception side apparatus measures a received quality of the data frame, decides a frame type based on the measured received quality and notifies the decided frame type to the transmission side apparatus. The transmission side apparatus sends subsequent frame data to the reception side apparatus in use of a frame format corresponding to the notified frame type.
