PURPOSE:To prevent a transmission amplifier of a mobile station from being divergent into a maximum transmission power in the control process by providing an upper limit to the maximum transmission power of the mobile station so that required quality is satisfied for a base station with respect to the maximum transmission power of the system. CONSTITUTION:A radio equipment of a base station controls transmission power of a mobile station so that a ratio of a desired wave reception signal power S from a mobile station making talking to the sum of thermal noise and an interference signal power I from other mobile station satisfies required reception quality. The period of the power control is selected to be less than a period at which instantaneous fluctuation in response to a Doppler frequency is traced. When a level of an interference signal is increased, the transmission power PT of the mobile station is increased to reach a mobile station maximum transmission power Pmax depending on the extension subscriber capacity of the system, cell diameter and a location rate, the power is fixed at the power Pmax for the transmission. Thus, the transmission power of the mobile station is not increased over the maximum transmission power Pmax corresponding to a maximum signal level Smax of the base station. |
