In a method for controlling output power of a handheld terminal in a mobile communication system capable of performing various power controls according to a modulation method and generating various TPC coding values by applying an additional variable to an APC (automatic power control) signal, the method includes generating each TPC (transmit power control) coding value according to handheld terminal transmit output characteristics; setting a uplink Eb/No reference value about all handheld terminals and comparing an Eb/No about generated each TPC coding value with the reference value; selecting an optimum power control command by a base station and transmitting the selected command value to the handheld terminal periodically; and adjusting a transmit power level of the handheld terminal by answering to TPC coding about the selected power control command value. Accordingly, it is possible to minimize current consumption and control uplink output power of a handheld terminal as an optimum state by applying the present invention to various communication environments. <IMAGE>
