ABSTRACT:
A subscriber unit (200) adjusts transmitter power during a subscriber call by transmitting a first message at a first power level (10) that decreases (80) to a second minimum required power level (60) within a predetermined duration to a second subscriber unit (300), receiving a reply message from the second subscriber unit, the reply message including a code representing a desired transmitting signal strength (20) of the first subscriber unit as determined by the second subscriber unit based on the predetermined duration (70) and the second minimum required power level (20), determining a value representing the desired transmitting signal strength of the first subscriber unit of the reply message, adjusting the power level based on the value representing the desired transmitting signal strength, and then transmitting a second message at the desired transmitting signal strength to the second subscriber.
