Description of the Related Art A conventional transmission power control method in a radio station sets a master-slave relationship for control between two radio stations facing each other, and a transmitter / receiver of a master radio station is a slave station. It is equipped with means for monitoring the signal status of the other station and means for calculating the appropriate transmission power of the other station based on the signal status of the other station and outputting control information, and transmitting the transmission power control information to the other station from the own station. It is configured to be added to the signal.
The other station, which is a slave, extracts the transmission power control information for the own station and increases or decreases the transmission power of the own station. This is used in a communication system such as satellite communication in which a master-slave relationship for control is clear (see Japanese Patent Laid-Open Nos. 2-33328 and 2-33229).
