The present application claims priority to the Chinese Patent Application filed on February 13, 2017, the Chinese Patent Office, Application No. 201710076888.0, entitled "Method and Apparatus for Changing the Working Mode of the PA According to the Work Scene in a WiFi System", The entire contents are incorporated herein by reference.

Technical field

The embodiments of the present application relate to a WiFi communication system, and in particular, to a voltage control method and a terminal.

Background technique

In a wireless fidelity (WiFi) communication system, it is usually necessary to provide a power amplifier (PA) with a voltage within the allowable range of the device (such as 3.3V-5V) as the 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 supply voltage is as follows: 1. When the supply voltage is high voltage (close to the above specification, the upper limit voltage, such as 5V voltage) When the linearity of PA is high, the output power value corresponding to 1db compression point is higher, but the efficiency of PA is lower, the overall power consumption of PA is larger; Second, when the supply voltage is low voltage (close to the above specification allowable range) When the internal lower limit voltage is 3.5V, the linearity of the PA is low, and the output power value corresponding to the 1 db compression point is low, but the efficiency of the PA is high, and the overall power consumption of the PA is small.

In the prior art, a solution for providing a fixed supply voltage (such as a fixed high voltage or a fixed low voltage) for the PA according to the priority of linearity and efficiency in the WiFi system is provided for the PA, such as when the linearity priority is greater than For efficiency priority, the PA is powered by a high voltage close to the upper limit voltage within the allowable range of the above specifications. When the efficiency priority is greater than the linearity priority, the low voltage of the lower limit voltage within the allowable range of the above specifications is used to supply the PA.

In the prior art, when a high voltage is supplied to the PA, the linearity of the PA is high, and at the same time, the efficiency of the PA is lowered, and the power consumption is increased. When the low voltage is supplied to the PA, the efficiency of the PA is high, and the power consumption is lowered. At the same time, the linearity of the PA is lowered. Therefore, in the actual working scenario, the solution for providing a fixed supply voltage for the PA cannot meet the different requirements of the linearity and efficiency of the PA in different working scenarios. For example, the linearity requirement of the PA in some working scenarios is higher than the efficiency requirement, and the other part. The working scenario has a higher efficiency requirement for the PA than the linearity requirement.
