Problems solved by technology

[0004] However, the current method has the following disadvantages: 1. Reducing the receiving gain of the device will reduce the receiving performance of the wireless communication device, such as transmission distance, received signal quality, and unbalanced uplink and downlink gains; 2. Reduce the number of RU devices in the network, It will reduce the coverage of the device and reduce the overall coverage power of the TX transmission.

Abstract

The present application relates to a method, device, system and readable storage medium for reducing base station reception noise, wherein the method for reducing base station reception noise includes obtaining a target RU device in the RU device network, and setting the power of the target RU device Threshold value; the attenuation value is obtained according to the actual received power of the target RU device, the power threshold value and the calibration value, and the calibration value is the baseband power value at which the RU device triggers ALC to start control; power attenuation is performed on the target RU device according to the attenuation value , to reduce the noise floor of the base station. The solution provided by this application increases the uplink attenuation by selecting RU devices that often reach the calibration value or are often in the ALC control state in the RU device network, so as to ensure that the overall noise floor of the RU device network meets the requirements, while reducing the background noise It can also guarantee the performance of the system to the greatest extent.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device, system and readable storage medium for reducing base station reception noise. Background technique [0002] At present, communication base stations such as macro stations, BBUs, or micro-macro stations in wireless communication have high requirements for receiving noise floor. Generally, the average value of uplink noise floor or the absolute power of a single RB block is required to be less than -110dBm. Therefore, higher requirements are placed on the uplink reception noise floor of distributed devices such as Distributed Antenna System (Distributed Antenna System, DAS) and repeaters. [0003] At present, there are generally two methods to solve the uplink noise floor of the wireless receiver: 1. Directly increase the attenuation value of the radio frequency on the uplink port of the RU or the uplink port of the AU, such as reducing the receivin...
