Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0022] An embodiment of the present invention provides a power control method, such as figure 1 As shown, the method includes:

[0023] S101. Determine whether the power amplifier is overloaded according to the maximum transmission power of the power amplifier and the total power demand of each traffic channel in the current time slot;

[0024] Here, the maximum transmission power of the power amplifier is also the rated power of the power amplifier. If the total power demand of each traffic channel in the current time slot is greater than the maximum transmission power of the power amplif...

Abstract

The embodiment of the invention discloses a power control method, comprising the step of reducing the transmission power of all or partial traffic channels of the current time slot according to the amplitude of reducing the transmission power, which is allowed by the traffic channels of the current time slot, the priority of the traffic channels and the power overload capacity if a power amplifier is determined to be overloaded. The embodiment of the invention also discloses a power control device and a base station. The scheme of the embodiment of the invention effectively reduces the impacton the quality of the traffic channels with high priority.

Description

technical field [0001] The present invention relates to communication technology, in particular to a power control method, device and base station. Background technique [0002] The multi-carrier system has the advantages of high integration and high energy efficiency ratio. The application of multi-carrier technology in communication network construction can reduce the basic construction cost of the operator's network construction, and at the same time realize the low operating cost of network maintenance. [0003] Currently, in a multi-carrier system, if the power amplifier is overloaded, the base station will simultaneously reduce the transmit power of all current channels. [0004] However, using the method in the prior art, if the process of reducing the transmission power is performed on all current channels at the same time, the channel quality of important services may be affected. Contents of the invention [0005] Embodiments of the present invention provide a p...
