1. An apparatus for dynamically controlling transmission power, comprising:

  • receiver means for receiving a signal from a remote station; and

    transmitter means for adjusting a transmission power for the received signal to an acceptable level following a transmission power increase,control processor means for determining the acceptable level by determining the cause of the transmission power increase, wherein the cause of the transmission power increase comprises at least one of a random fade condition or a continuing fade condition and whereinif the cause of the transmission power increase is determined to be a random fade condition, then reducing the transmission power at a first predetermined rate for a first predetermined time period in response to the transmission power increase;

    if the transmission power is still at an unacceptable level after reducing the transmission power at a first predetermined rate for a first predetermined time period, then continuing to reduce the transmission power at a second predetermined rate for at least one other predetermined time period following the first predetermined time period, wherein the first predetermined time period and the at least one other predetermined time period are either of equal or non-equal duration; and

    if the cause of the transmission power increase is determined to be a continuing fade condition, then maintaining the transmission power at the level of the transmission power increase.
