【摘要】    随着工信部5G商用牌照的发放,中国5G商用网络建设在中华大地上如火如荼地进行。5G网络规模的不断扩大,覆盖范围的不断拓宽,新建设的5G网络基站站点数比现有的4G网络多的多,也更加密集,5G关键技术之一的超密集组网就是该需求下的产物,超密集网络和传统蜂窝网络最大的不同就是基站或可接入点的密度,可接入点的类型多样性,因此所带来一系列的干扰,从而降低了网络传输的质量。对此,本文基于超密集组网网络,提出无线网络干扰管理的几种思路,为5G无线网络的干扰管理提供参考。

Abstract: with the issuance of 5G business license of MIIT, the construction of 5G business network in China is in full swing. With the continuous expansion of 5G network scale and coverage, the number of newly built 5G network base stations is more and more dense than the existing 4G network. Ultra dense networking, one of the key technologies of 5G, is the product of this demand. The biggest difference between ultra dense network and traditional cellular network is the density of base stations or access points, and the diversity of access points, so it is necessary to improve the quality of the network It brings a series of interference, which reduces the quality of network transmission. In this regard, based on the ultra dense network, this paper puts forward several ideas of wireless network interference management, which provides a reference for 5G wireless network interference management.

Key words: 5G; ultra dense networking; interference management

引言:

5G作為“新基建”的领头羊,是人工智能、物联网、云计算、区块链、大数据、视频社交等新技术新产业的信息联接平台,正在驱动新一轮科技革命和产业变革,成为数字经济发展的基石。5G时代,1000万-2000万个基站都是有可能的,相比4G时代500多万个基站,在数量上要多得多,并且5G 移动通信系统为了满足3GPP定义的三大应用场景:eMBB(Enhance Mobile Broadband)增强移动宽带,uRLLC(The Ultra Reliable Low Latency Communication)超可靠、低时延通信,mMTC(massive Machine Type of Communication)海量机器类通信(大规模物联网)带来的一系列问题,网络的超密集部署技术被广泛用作为5G的关键技术。超高密度组网网络技术通过在热点中高密度地安排无线网络基础结构,从而将系统容量提高到100倍,从而提高了频率多样性。在集中式网络部署的趋势下,系统中的小型基站与一小部分用户之间的距离越来越近,小区边缘的用户受到相邻小区的干扰,降低了系统吞吐量。……
