PROBLEM TO BE SOLVED: To provide a radio communication system which can the perform transmission current control of slave units according to a radio wave status. SOLUTION: A cordless telephone set (10) is composed of a master unit (20) and slave units (30, 40). The master unit (20) is provided with a RSSI (Received Signal Strength Indicator) detection part (27) which detects the RSSI of carrier waves transmitted from the slave units (30, 40), and the RSSI of interference waves, and a control part (26) which transmits transmission current control signals to the slave circuits (30, 40) based on a CI ratio obtained from a ratio of the RSSI of the carrier waves and the RSSI of the interference wave.
