A spectrum spread communication system having a plurality of mobile stations and a plurality of base stations that share the same frequency and independently operate is disclosed, wherein each of the base stations as a local base station and non-local base stations has a means for always transmitting a pilot signal (base station reference signal) at a constant power level, and wherein each of the mobile stations has a quality measuring means for measuring base station reference signals reception from the local base station and an adjacent base station as one of the non-local base stations, and a transmission power controlling means for controlling the power level of a signal transmitted from the relevant mobile station corresponding to the measured results in such a manner that when the relevant mobile station has approached the adjacent base station, the transmission power controlling means decreases the power level of the transmission signal. <IMAGE> |
