ABSTRACT:
A CRC judgment section103performs a CRC check on decoded data every transmission unit, and if there is an error in the data, updates a flag held in a flag holding section106from 0 to 1; an increment/decrement value calculation section105calculates a reference SIR increment/decrement value according to the state (0 or 1) of the flag; a reference SIR update section107adds the reference SIR increment/decrement value to the current reference SIR value to find a new reference SIR value; a comparison section109compares the received signal SIR value measured by an SIR measurement section108with the updated reference SIR value, and a transmission power control bit generation section110generates a transmission power control bit according to the result of the comparison.
