ABSTRACT:
A method and system is disclosed for passing a transmit/receive control signal and a power signal through a coax cable from a base transceiver station to a tower top device in a time division duplex communication system. After generating the transmit/receive control signal and a radio frequency signal for communications, the transmit/receive control signal modulates a separate timing control operating on a separate control frequency. It is then multiplexed on at least one coax cable along with the radio frequency signal and DC power. At the tower top device, the modulated transmit/receive control signal is converted back to a DC level for providing a time division duplex control reference.
