Patent ID: 7167718

Claim:
A transmission power control apparatus for a wireless communication apparatus for reducing a power value of a signal input to a power amplifier to the maximum allowable, input power value of said power amplifier or below, said transmission power control apparatus comprising: a setting part for setting a transmission power upper limit value of a call according to a circuit type of said call, wherein the circuit type includes a packet switching type and a circuit switching type, said transmission power upper limit value comprising a first transmission power upper limit value and a second transmission power upper limit value, wherein the first transmission power upper limit value corresponds to the packet switching type call and the second transmission power upper limit value corresponds to the circuit switching type call, wherein the first transmission power upper limit value is lower than the second transmission power upper limit value; and a power reducing part for reducing transmission power for said call to or below said transmission power upper limit value depending on said call type, wherein, said setting part reduces said first upper limit value by a first predetermined ratio when said over-input to said power amplifier occurs, and said setting part increases said first upper limit value by a second predetermined ratio which is lower than said first predetermined ratio when said over-input to said power amplifier does not occur.
