【摘要】：移动通信技术地发展与日俱增,从第二代(2G)、第三代(3G)、第四代移动通信技术(4G)到当下全球各个国家均在着重发展的第五代移动通信系统(5G)。与之同时的是,我国的移动通信用户大量增长,各种移动新兴业务也相继产生,持续增加的用户数目和业务种类不停地刺激着我国已经划分的移动通信系统(IMT)频谱资源。并且,国家计划在2020年商用第五代移动通信系统,因此,5G系统的频谱需求研究迫在眉睫。本文首先阐述了目前IMT系统的发展现状和我国IMT频谱规划情况,并整理了现在国内外主流的IMT系统频谱需求预测方法,总结归纳了各种方法的优点和缺点。然后,根据未来5G系统的关键能力指标(KPI),使用基于KPI分场景的频谱需求方法计算5G典型场景频谱需求,结果显示未来5G系统的频谱需求量较大,根据热点基站和小基站的部署特点,2030年时6GHz以下频段5G系统的频谱需求是2720M,24.25-86GHz频谱范围内的频谱需求大约是24.3GHz。紧接着,从我国IMT系统实际密集城区场景的情况考虑,提出了一种基于Gompertz曲线的频谱需求预测方法,从预测的结果来看,未来商用5G系统后需要的频谱量将会受到多种因素的影响,每一种因素的改变,都将引起5G系统的频谱需求动态变化。本文通过两种不同的方法,从不同角度对5G典型场景频谱需求进行计算,具有便于实现的特点,可以有效地体现2030年时我国5G典型场景的频谱需求情况,对未来频谱的规划有重大意义。
[Abstract]:The development of mobile communication technology is increasing, from the second generation (2G), the third generation (3G), the fourth generation mobile communication (4G) to the fifth generation mobile communication system (5G), which is being developed in all countries all over the world. At the same time, the number of mobile communication users in China has increased greatly, and a variety of new mobile services have emerged. The number of users and the types of services continue to stimulate the (IMT) spectrum resources of the mobile communication system that has been divided in our country. Moreover, the state plans to use the fifth generation mobile communication system in 2020, so it is urgent to study the spectrum requirement of 5G system. In this paper, the current development of IMT system and the IMT spectrum planning in our country are described, and the main methods of spectrum demand prediction for IMT system are summarized, and the advantages and disadvantages of these methods are summarized. Then, according to the key capability index of 5G system in the future, (KPI), uses the spectrum requirement method based on KPI sub-scene to calculate the spectrum requirement of 5G typical scene. The result shows that the spectrum demand of 5G system in the future is large. According to the deployment characteristics of hot base station and small base station, the spectrum requirement of 5G system under 6GHz frequency band is about 24.3 GHz in the frequency range of 2720MN 24.25-86GHz in 2030. Then, considering the actual situation of dense urban area of IMT system in our country, a spectrum demand forecasting method based on Gompertz curve is proposed. In the future, the amount of spectrum required after commercial 5G system will be affected by many factors. The change of each factor will cause the dynamic change of spectrum demand of 5G system. Through two different methods, this paper calculates the spectrum requirement of 5G typical scene from different angles, which is easy to realize and can effectively reflect the spectrum requirement of 5G typical scene in 2030. It is of great significance to the planning of the future spectrum.
