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