Abstract
According to an aspect of the present disclosure, there is provided a method of controlling a power amplifier in a low-orbit satellite network, the method comprising: communicating, by a terminal, with a satellite; setting an initial applied voltage and frequency; receiving orbit information from the satellite; and updating the initial applied voltage according to the orbit information and network environment.

A method of controlling a power amplifier in a low-orbit satellite network, the method comprising:
- communicating, by a terminal, with a currently-communicating satellite;
- setting an initial applied voltage and frequency;
- receiving orbit information from the satellite;
- and
- updating the initial applied voltage according to the orbit information and network environment;
- wherein when a signal strength transmitted by the terminal to the currently-communicating satellite is greater than or equal to a predetermined threshold, the initial applied voltage is updated based on information on a distance between the currently-communicating satellite and the terminal and information on an inclination angle at which the terminal is facing the currently-communicating satellite.
An apparatus for controlling a power amplifier in a low-orbit satellite network, the apparatus comprising:
- a memory including instructions;
- and
- a processor configured to execute the instructions to thereby communicate, by a terminal, with a currently-communicating satellite, set an initial applied voltage and frequency, receive orbit information from the currently-communicating satellite, and update the initially applied voltage according to the orbit information and network environment;
- wherein when a signal strength transmitted by the terminal to the currently-communicating satellite is greater than or equal to a predetermined threshold, the initial applied voltage is updated based on information on a distance between the currently-communicating satellite and the terminal and information on an inclination angle at which the terminal is facing the currently-communicating satellite.
