Problems solved by technology

This adjustment method has a certain hysteresis, and is more suitable when the output power is relatively stable. However, when the output power is not stable, such as when the signal rapidly fades, the output power of the power amplifier of the base station may change rapidly. The previous power control ...

Embodiment Construction

[0035] Embodiments of the present invention provide a power amplifier voltage adjustment method and device in a wireless communication system, which determines the power amplifier voltage value of the current power control cycle by obtaining the power control level of the current power control cycle, and according to the determined power amplifier voltage Adjust the power amplifier voltage in the current power control cycle to achieve real-time adjustment of the power amplifier voltage value, so that the power consumption matches the output power of the current power control cycle, so that when the power amplifier provides the required output power, the power amplifier is able to provide the power. On the smaller power consumption of the output power, the efficiency of the power amplifier is improved.

[0036] Such as figure 1 As shown, the power amplifier voltage adjustment method in the wireless communication system provided by the embodiment of the present invention include...

Abstract

The invention discloses a method and a device for adjusting power amplifier voltage of a wireless communication system, belonging to the wireless communication technology. The method comprises the following steps: obtaining the power control level of a current power control period, determining the voltage value of a power amplifier in the current power control period according to the corresponding relationship table of the power control level and the voltage value of the power amplifier, and regulating according to the determined voltage value. Since the corresponding relational table of the power control level and the voltage value of the power amplifier is set according to the empiric value with higher power amplifier efficiency, the power amplifier can operate with higher efficiency when the voltage value of the power amplifier is adjusted to a voltage value corresponding to the current power control level.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method and device for adjusting power amplifier voltage in a wireless communication system. Background technique [0002] In a wireless communication system, the power amplifier is one of the devices with high power consumption in the wireless communication system, and the efficiency of the power amplifier is obtained by dividing the transmit power by the power consumption of the power amplifier. From the number of carriers output at the same time, the power amplifier can be simply divided into two categories, one is single carrier power amplifier, one power amplifier only outputs one carrier signal at the same time, and the other is multi-carrier power amplifier, which can output more than two carrier signals at the same time . [0003] At present, in order to reduce the mutual interference between wireless signals, the transmission power of the signal in the wirel...
