A control apparatus for controlling a wireless communication system, which provide enhanced communication efficiency when a single apparatus performs a plurality of wireless communications. A timing signal generation logic circuit generates transmission and reception timing control signals for controlling timing of transmission and reception by respective ones of a Bluetooth module and a wireless LAN module based on respective states thereof. MAC sections of the respective modules control transmission and reception by the respective ones of the Bluetooth module and the wireless LAN module, based on the respective corresponding transmission and reception timing control signals generated by the timing signal generation logic circuit.
