Abstract
A wireless communication apparatus includes a variable power amplifier () and a power amplifier (). A variable power amplifier control unit () controls the gain of the variable power amplifier () for controlling transmission power of the own apparatus. At this time, a condition change detecting unit () detects changes in conditions of the own station and a counter station. Based upon the detected condition changes, a transmission power control bit controlling unit () and a transmission power control period controlling unit () change a control period of a transmission power control bit and a transmission power control range. This transmission power control bit is inserted into a transmission signal, then, the transmission signal is transmitted to the counter station. The condition changes are detected based upon reception power, transmission power, the transmission power control bit, a change amount of control conditions, and a change speed of the control conditions.
