Abstract
In a communication terminal that performs bidirectional communication using different frequencies for transmission and reception, a receiving unit receives reception signals transmitted from the base station, a detecting unit detects the timing of DL when the receiving unit receives the reception signals, an adjusting unit adjusts the timing of UL to transmit the transmission signals so as to synchronize the timing of the DLand the timing of the UL, and a transmitting unit transmits transmission signals to the base station based on the timing of UL adjusted.
