In a transmission signal generating circuit, spreading processing circuits spread transmission data to output spread transmission signals. Power class selecting circuits categorize the spread transmission signals into power classes. First adding circuits add/combine the spread transmission signals. Multipliers adjust transmission powers of the spread transmission signals for the respective power classes. A second adding circuit adds/combines the spread transmission signals. A total transmission power measuring means measures a total transmission power. A nonlinear quantization means nonlinearly quantizes the total transmission power and outputs a power level. A power limitation control memory outputs a multiplication coefficient for a power class for which transmission power control is permitted. Selectors select a multiplication coefficient from said power limitation control memory when transmission power control is permitted for the power class and output it to the multiplier corresponding to the power class, and select a multiplication coefficient formed from a predetermined fixed value when transmission power control is inhibited for the power class and output it to the multiplier corresponding to the power class. A radio base station communication apparatus is also disclosed. <IMAGE> |
