A signal is prevented from being transmitted from a mobile station to a base station with excessive transmission power for thereby increasing an uplink capacity. The base station compares the reception quality of the signal transmitted from the mobile station with target reception quality, and determines an increment for transmission power of the base station based on a compared result. The base station adds the increment to the transmission power of the base station based on a second control command transmitted from the mobile station, and transmits a first control command for controlling transmission power of the mobile station with the transmission power to which the increment has been added. If the reception quality of the signal transmitted from the mobile station becomes greater than the target reception quality, then the increment for the transmission power is increased. If the reception quality of the signal transmitted from the mobile station becomes smaller than the target reception quality, then the increment for the transmission power is reduced.

1. A method of controlling transmission power in a cellular system having a plurality of cells, a plurality of base stations disposed respectively in the cells, and a mobile station disposed in one of the cells and having a link established with one or more of said base stations for communicating therewith with a transmission power based on a first control command transmitted from the base station, comprising the steps of:determining transmission power of the base stations based on a second control command transmitted from the mobile station; measuring reception quality in the base stations of a signal transmitted from the mobile station; comparing the measured reception quality with target reception quality; determining an increment for the transmission power of the base stations which has been determined based on said second control command, based on a compared result; incrementing the transmission power of the base stations by the determined increment; and transmitting the first control command for controlling transmission power of the mobile station from the base stations to the mobile station, with the incremented transmission power.
