Method and device for adjusting power amplifier voltage

摘要

A method and a device for adjusting a power amplifier voltage are provided. A method for adjusting a power amplifier voltage includes: determining, by a base station, a power amplifier voltage in a statistical time period according to carrier power control information and a relation between a power amplifier output power and a power amplifier efficiency; selecting a power amplifier voltage in the previous statistical time period of the statistical time period of the current time point as a target power amplifier voltage; and adjusting a power amplifier voltage at the current time point according to the target power amplifier voltage. A power amplifier of a multi-carrier module works in a linear amplification area in the statistical time period. Through the method, dynamic adjustment of a power amplifier voltage and dynamic time slot control may be realized for the multi-carrier module.
