Abstract:
A method of compensating for reverse channel interference in a code division multiple access (CDMA) open loop control on the basis of received reverse channel interference power to control transmission power of a mobile station, wherein said method comprising the steps of:measuring, in a base station, a plurality of received interference powers of a reverse channel at respective times to produce measured received power values; calculating, in said base station, an average of the measured received power values to produce a calculated average value indicative of the average reverse channel interference power; calculating, in said base station, on the basis of the calculated average value and a reference value, a correction value for making said mobile station increase a current transmission power so as to become larger than a previous transmission power; transmitting information indicative of the correction value from said base station to said mobile station; receiving, in said mobile station, the information comprising the correction value; determining, in said mobile station, whether the received correction value differs from a current correction value; and setting, in said mobile station, transmission power of said mobile station on the basis of the received correction value if the received correction value differs from the current correction value.
