Document Type and Number:
WIPO Patent Application WO/2010/133178
Kind Code:
A1
Abstract:
A method, device and system for adjusting power amplifier voltage and controlling time slots occupation are provided. Wherein, a method for adjusting power amplifier voltage includes: determining, by a base station, power amplifier voltage during a statistics time period according to carrier power control information and the relationship between power amplifier output power and power amplifier efficiency; selecting the power amplifier voltage during the statistics time period before the statistics time period containing the current time point as object power amplifier voltage; adjusting the power amplifier voltage at the current time point according to the object power amplifier voltage; wherein, during the statistics time period, the power amplifier of the multi-carrier module works in the linear amplification range. The application of the method in embodiments of the present invention can implement dynamically adjusting the power amplifier voltage of the multi-carrier module and dynamically controlling time slots for the multi-carrier module.
