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.
Claims19
A communication device, comprising:
- 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.
A method for controlling power of a communication device, the method comprising:
- comparing predetermined downlink reference information with output signal information on an output signal obtained by amplifying a downlink signal using a supply voltage;
- determining whether a current state of the device is an idle state based on a comparison result;
- and
- if it is determined that the current state of the device is the idle state, controlling the supply voltage.
A method for controlling power of a communication device, the method comprising:
- comparing predetermined uplink reference information with uplink signal information on an uplink signal;
- and
- determining whether the current state of the device is the idle state based on a comparison result;
- if it is determined that the current state of the device is the idle state, controlling a supply voltage for amplifying a downlink signal.
