The automatic control system of a mobile terminal for time division duplex (TDD) based communication system includes an RF processing module which controls quality of a transmission channel, and a baseband modem connected to the RF processing module through a transmission data line and a reception data line. The baseband modem generates automatic control signals based on control information received from a base station and transmitting the automatic control signal to the RF processing module through the transmission data line in a reception mode of the mobile terminal. The automatic control signals are transmitted to the RF processing module through the transmission data line, which is in the idle state, in the reception mode. Additional control lines are not required to transmit the respective automatic control signals. Therefore, utilization of the transmit data line between the baseband modem and the RF processing module can be improved.
