Abstract:
A mobile communication system comprising:a base station for transmitting base station information containing transmission power information on the power level with which the base station is transmitting signals to a mobile station, and a code specifying the particular base station itself;a mobile station which controls its own transmission power in accordance with (i) the transmission power information in the received base station information on the power level with which the base station is transmitting signals to the mobile station, and (ii) a reception electric field strength of the signals received from the base station by the mobile station as measured by the mobile station;wherein the mobile station stores an array of data comprised of (i) a plurality of base station transmission power levels and (ii) a plurality of reception electric field strengths for each of the plurality of base station transmission power levels, and wherein a particular base station transmission power level and a particular reception electric field strength indicate a particular mobile station transmission power level, from which a selected transmission power with which the mobile station is to perform transmission is selected from the array of data on the basis of (i) the transmission power information received from the base station, and (ii) the reception electric field strength measured by the mobile station; andthe mobile station performs a transmission to the base station at said selected transmission power.
