1. An open loop method of controlling the power of a remote transmitted signal transmitted by a remote communication device to a base communication device in a frequency channel in a first time period, said base device transmitting to said remote device a base transmitted signal in the frequency channel in a second time period different from the first time period, said method comprising:

  • receiving said base transmitted signal in the frequency channel by said remote device;

    measuring the power of said base transmitted signal received by said remote device; and

    controlling the transmission power of the remote transmitted signal in the frequency channel in accordance with
    
    
    space="preserve" listing-type="equation">Power=A+(B-C) where A is representative of the desired power of the remote transmitted signal received by the base device;

    B is representative of the power of the base transmitted signal;

    C is representative of the measured power of the base transmitted signal as received by the remote device.
