Abstract
A communication device for power saving and a method for controlling power thereof are provided. The communication device includes a power amplifying unit and a control unit. The power amplifying unit generates an output signal obtained by amplifying a downlink signal, using a supply voltage, and outputs the output signal. The control unit determines a current state by comparing predetermined downlink reference information with output signal information on the output signal, and, if the current state is an active state as a comparison result, controls the supply voltage to correspond to the output signal information. Accordingly, power for amplifying a signal can be controlled according to communication traffic, thereby preventing consumption of unnecessary power.
