When a base station receives a frame error rate from a mobile station (step 202) and finds that the rate is higher than a predetermined rate range (step 203), they increase transmission power level Pf by DELTA P (step 204). When the frame error rate is lower than the predetermined rate range (step 205), the base station reduces the transmission power level Pf by DELTA P (step 206). When the base station finds that the result D of measurement of the desired wave power level is higher than a predetermined desired control level T (step 207), it provides a level reduction command as transmission power level control command (step 208), and sets (Pf+Padd) as the transmission power level P (step 209). The base station sends the control command to the mobile station. When the desired wave power level measurement result D is lower than the desired control level T (step 207), it provides a level increase command as the control command (step 210). Then, it sets the transmission power level P to be Pf, and sends the control command to the mobile station (step 212). <IMAGE> |
