| 1. An apparatus for controlling reverse TX power in a mobile terminal, the apparatus comprising:
a closed-loop power controller for limiting a TX power increase due to a power control bit of an RX signal by using a power-up
limit bit and outputting a closed-loop power control value for decreasing the TX power when a TX power limit mode is selected;
an adder for calculating a TX power by adding the closed-loop power control value and an open-loop power set using a power
of the RX signal; and
a maximum TX power limiter for setting a final TX power by subtracting a maximum TX power limit reference value determined
according to an RX signal strength in the mobile terminal from the calculated TX power.
