Problems solved by technology

[0005] In the prior art, when a high voltage is provided for the PA, the linearity of the PA is high, and at the same time, the efficiency of the PA is reduced, and the power consumption is increased; when a low voltage is provided for the PA, the efficiency of the PA is high, and the power consumption is reduced , at the same time, resulting in a decrease in the linearity of the PA
Therefore, in actual working scenarios, the scheme of providing a fixed power supply voltage for PA cannot meet the different requirements of PA for linearity and efficiency in different working scenarios. In the work scene, the efficiency requirement of PA is higher than the linearity requirement

Abstract

A voltage control method and a terminal, which are used to change the voltage level of the output voltage to meet the different requirements for linearity and efficiency of power amplifiers in different working scenarios. The method includes: the terminal determines the target parameter of the transmit frame according to the link quality of the target link (201), the target link is a link used to send the transmit frame, and the target parameter is a related parameter representing the quality of the link; when the target parameter When the first preset condition is met, the terminal outputs the first voltage (203), so that the power amplifier operates in a high linearity mode; when the target parameter meets the second preset condition, the terminal outputs the second voltage (204), to Make the power amplifier work in high efficiency mode.

Description

[0001] This application claims the priority of the Chinese patent application filed on February 13, 2017 with the application number 201710076888.0 and the invention titled "A method and device for changing the PA working mode in a WiFi system according to the working scene". The entire contents of this application are incorporated by reference. technical field [0002] The embodiments of the present application relate to a WiFi communication system, and in particular, to a voltage control method and terminal. Background technique [0003] In wireless fidelity (WiFi) communication systems, it is usually necessary to provide a power amplifier (PA) with a voltage within the allowable range of device specifications (such as 3.3V-5V) as the power supply voltage of the PA, so that the PA In normal working state, at this time, the relationship between PA performance parameters (such as linearity, efficiency) and external power supply voltage is: 1. When the power supply voltage is...
