Problems solved by technology

Therefore, there is a problem in that the number of base stations to be deployed in such a communication system increases
[0011] However, the supply voltage supplied by the mobile terminal to its internal components is limited to a predetermined value or less
In particular, depending on the state of charge of the mobile terminal, such a supply voltage cannot be maintained at this level, and therefore, the supply voltage to the power amplifier decreases
Therefore, even if necessary, the mobile terminal cannot perform high power transmission due to the limitation of the supply voltage to the power amplifier

Abstract

A mobile terminal for performing power control in accordance with the present invention comprises: a power tracker configured to supply a supply voltage to a power amplifier; and a bypass booster disposed between the battery and the power tracker and configured to boost the voltage from the battery through a booster or bypass without boosting the voltage through the booster, and the mobile terminal can also increase communication coverage in a new communication system in a higher frequency band.

Description

technical field [0001] This application claims the benefit of priority to U.S. Provisional Patent Application Serial No. 62 / 655,173, filed April 9, 2018, the contents of which are incorporated herein by reference. [0002] The present disclosure relates to a mobile terminal configured to control power. More particularly, the present disclosure relates to a power control method for high power transmission and a mobile terminal performing the method. Background technique [0003] According to mobility, terminals can be classified into mobile / portable terminals and stationary terminals. Mobile terminals can also be classified as handheld terminals or vehicle mount terminals according to whether a user can directly carry the terminal. [0004] The functions of mobile terminals have become more and more. Examples of these functions include data and voice communications, capturing images and video via a camera, recording audio, playing music files via a speaker system, and disp...
