Patent

CA 2376321

A method and subscriber unit (SU) for using Maintenance Power Control (MPC) for wireless communication with a base station in a wireless communication system. The SU includes a transmitter, a receiver and associated MPC circuitry. When in an awake phase, the transmitter transmits signals to the base station. When in a sleep phase, the transmitter is configured to become periodically active to transmit a status signal to the base station. The receiver and associated MPC circuitry are configured to adjust a selected initial power lever downwardly when a reply signal is received, and upwardly when no reply signal is received within a predetermined time period of the transmission of the status signal. Thus, the selected initial power level is maintained at a level for efficient system communications.
