US 9,854,541 B2 · Communication device and method for controlling power thereof

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.

A communication device, comprising:

a power amplifier configured to generate an output signal obtained by amplifying a downlink signal, using a supply voltage, and output the output signal;
and
a processor configured to:
determine a current state by comparing predetermined downlink reference information stored in a storage with output signal information indicating power of the output signal,
if the current state is an active state as a comparison result, control the supply voltage to correspond to the output signal information,
if the current state is an idle state and a current time does not correspond to predetermined first idle time information, control the supply voltage to correspond to a first voltage, generate second idle time information indicating a time when the current state is determined to be the idle state, and store the second idle time information to the storage unit, and
if the current state is the idle state and the current time corresponds to the first idle time information, control the supply voltage to correspond to a second voltage which is a voltage lower than the first voltage, wherein, if the time when the current state is determined as the idle state is repeated m times, the processor generates the second idle time information, wherein the m is a natural number of 2 or more,
wherein communication traffic of the active state is higher than communication traffic of the idle state, and
wherein the first idle time information and the second idle time information indicate when the idle state repeatedly occurs.

and
if the current time corresponds to the first idle time information, controlling the supply voltage to correspond to a second voltage which is a voltage lower than the first voltage, wherein, if the time when the current state is determined as the idle state is repeated m times, the processor generates the second idle time information, wherein the m is a natural number of 2 or more,
wherein communication traffic of the active state is higher than communication traffic of the idle state, and
wherein the first idle time information and the second idle time information indicate when the idle state repeatedly occurs.
