<p>A communication system is provided to decrease or prevent unbalance between a measured value for the quality of a communication signal received to a destination apparatus and a measured value for the quality of a communication signal received to an intermediate apparatus and minimize excessive Tx power. A communication system comprises a base station, a destination apparatus, and an intermediate apparatus. The base station transmits communication signals to the intermediate apparatus or to the destination apparatus through the intermediate apparatus. The destination apparatus comprises an indicator deduction unit. The indicator deduction unit deduces more than one indicator for the quality of the communication signals received to the destination apparatus. Also the communication system comprises a control unit, an indicator deviation detection unit, and a decision unit. The control unit is provided for the base station. The indicator deviation detection unit detects a deviation from a desired value of a deduced indicator. After the detection of such a deviation, the decision unit determines a change, which is inclined to lead the indicator to the desired value, for the Tx power of the intermediate apparatus. The decision unit comprises a request transmitting unit. The request transmitting unit transmits a change request for the Tx power of the intermediate apparatus to the control unit.</p> |
