ABSTRACT:
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).
