Transmission power control apparatus and method and radio communication apparatus

摘要

The transmission power control apparatus includes a section (101) for calculating the reception power of a desired radio wave from the received signal, section (102) for storing the reception power above, section (105) for storing past transmission power, section (103) for demodulating the control signal periodically included in the received signal and section (104) for determining the transmission power set value above, and determines a transmission power set value using the past transmission power, reception power of the desired radio wave and the control signal.
