Abstract:
1. A portable wireless transceiver, comprising: a receiving unit receiving a signal from a base station; a transmitting unit transmitting a signal to said base station with a transmission power in accordance with a control signal value; a transmission power finding unit finding the control signal value that changes stepwise, corresponding to a transmission power request received from said base station through said receiving unit, by accessing a first table storing a relation between step values and control signal values for corresponding transmission power set values; a limit value determining unit detecting a state of said transmitting unit and determining a limit value for said control signal value that changes stepwise based on the detected state; and a power control unit controlling the transmission power of said transmitting unit in accordance with the control signal value found by said transmission power finding unit, and when the control signal value found by said transmission power finding unit exceeds the limit value of said limit value determining unit, controlling the transmission power of said transmitting unit in accordance with said limit value to not exceed said limit value.
