Remote radio unit and power consumption limitation method thereof, and base station controller

Abstract

The embodiment of the invention relates to a remote radio unit (RRU) and a power consumption limitation method thereof, and a base station controller. The RRU comprises a power amplification unit, a power consumption detection unit, a power consumption monitoring unit and a power consumption control unit, wherein the power amplification unit is used for amplifying radio power; the power consumption detection unit is used for acquiring the power consumption of the RRU by detecting the power consumption of the power amplification unit and supplying a detected result to the power consumption monitoring unit; the power consumption monitoring unit is used for calculating a power consumption value of the RRU according to the detected result of the power consumption detection unit and supplying the value to the power consumption control unit; and the power consumption control unit is used for controlling the power consumption of the power amplification unit according to a highest power consumption identification command and a highest power consumption threshold value which are sent from the outside to ensure that the power consumption value of the RRU is less than the highest power consumption threshold value. According to the RRU and the power consumption limitation method thereof and the base station controller, the power consumption of the RRU can be reduced effectively.

Description

technical field [0001] The present invention relates to a mobile communication system, in particular to a remote radio unit (RRU, Remote Radio Unit) in a base station, a method for limiting power consumption thereof, and a base station controller (BSC, Base Station Controller). Background technique [0002] In the base station system, the power consumed by the remote radio unit (RRU) accounts for the largest proportion. Generally, in a base station system, one or more remote radio frequency units (RRU) are configured to implement wireless access. The RRU implements the output of the radio frequency signal of the air interface, and the greater the output power of the radio frequency signal, the greater the power consumption of the RRU. [0003] When the power supply to the RRU is limited or the power consumption of the RRU needs to be reduced, the maximum power consumption of the RRU needs to be controlled. When the capacity of the power supply is limited, it is necessary t...

Problems solved by technology

[0005] In the above-mentioned prior art, the power consumption of the RRU can be limited by reducing the radio frequency output power of the RRU, but it is impossible to accurately grasp the degree of reduction of the power consumption of the RRU

In addition, in the case of limiting according to the specifications, the output power of the RRU can be controlled, but the individual differences between each RRU cannot be controlled, and the problem of excessive power reduction or excessive power consumption of a single RRU may occur
