中国首份5G频谱白皮书

我们特别注意到，中国首份5G频谱白皮书中所建议的可用于5G移动通信的频段是：

（1）低于6GHz的频段：建议把3.3-3.6GHz、4.4-4.5GHz、4.8-4.99GHz用于5G；

（2）高于6GHz的频段：24.25GHz-86GHz中的11个频段，尤其是其中的24.25-27.5GHz（可作为早期5G部署的“先锋”频段）、31.8-33.4GHz、37-43.5GHz。

具体内容，请大家详细查阅中国首份5G频谱白皮书中的下述精彩内容（里面有很多“干货”）：

一、中国5G频谱研究进展
The common view from IMT industry regarding 5G spectrum in China is that 5G system need to support aggregation of frequency ranges： frequency bands below 6GHz for 5G coverage and capacity， high frequency band （above 6GHz） for 5G capacity and backhaul.
On January 7th， 2016， MIIT launched China 5G Technology R&D Trial to promote the development of 5G technology and standard in 3.4-3.6 GHz band. It was also planned to conduct IMT vs. FSS compatibility trial from 2016 to 2017 in this band.
At the WRC-15， China supported the identification of 3.3-3.4GHz， 4.4-4.5GHz， and 4.8-4.99GHz frequency bands for IMT under the discussion of WRC-15 agenda item 1.1. Although China did not join the footnotes （i.e. Footnote 5.429F to identify 3.3-3.4GHz band for IMT and Footnote 5.441B to identify 4.8-4.99GHz band or partial of the band for IMT， in listed region 3 countries） in the Radio Regulations， China is making progress in domestic coordination towards the IMT identification in 3.3-3.4GHz， 4.4-4.5GHz， and 4.8-4.99GHz frequency bands in Chinese Regulations on the Radio Frequency Allocation.
It was expected that C band will be the key 5G band in China， particular for initial 5G deployment.
To evaluate the spectrum requirements and candidate frequency bands for IMT in high frequency band， especially in the frequency ranges listed in WRC-19 agenda item 1.13 from 24.25 to 86 GHz， operators， manufacturers， and research institutes are conducting studies under the director of MIIT within the WRC-19 preparatory mechanism in China. The research ongoing include spectrum needs， simulation models， propagation models， IMT parameters， sharing and compatibility studies. China administration supports the activities to promote global/regional harmonization of 5G spectrum under WRC-19 agenda item 1.13. At this stage， China is taking more concentration on the sharing and compatibility studies in 26GHz and 40GHz frequency bands.
二、中国5G频谱需求
China mobile market is the biggest market in the world in terms of number of subscribers and numbers of BSs deployed and devices. And the growth of China mobile data traffic is close to the high end of the world development.
The mobile data traffic is expected to grow by more than 300 times from 2010 to 2020 and by more than 40，000 times from 2010 to 2030. For developed cities and hotspots in China， the growth of mobile data traffic will exceed the average growth for all of China. For example， from 2010 to 2020 in Shanghai， the mobile data traffic is projected to grow by 600 times. In Beijing and during this same period， it is estimated that hotspot traffic may grow by up to 1，000 times. The total number of devices connected by the mobile communications network will reach 2 compared to the global number of 10 billion. The number of IoT connections will also expand rapidly， reaching 1.5 billion.
应用场景
Below 6GHz used for seamless wide-area coverage， 24.25-43.5GHz： fulfill the indoor and outdoor hot spot capacity requirement. And 45.5-86GHz： fulfill the indoor hot spot capacity requirement.
