【摘要】：移動通信技術(shù)地發(fā)展與日俱增,從第二代(2G)、第三代(3G)、第四代移動通信技術(shù)(4G)到當(dāng)下全球各個國家均在著重發(fā)展的第五代移動通信系統(tǒng)(5G)。與之同時的是,我國的移動通信用戶大量增長,各種移動新興業(yè)務(wù)也相繼產(chǎn)生,持續(xù)增加的用戶數(shù)目和業(yè)務(wù)種類不停地刺激著我國已經(jīng)劃分的移動通信系統(tǒng)(IMT)頻譜資源。并且,國家計劃在2020年商用第五代移動通信系統(tǒng),因此,5G系統(tǒng)的頻譜需求研究迫在眉睫。本文首先闡述了目前IMT系統(tǒng)的發(fā)展現(xiàn)狀和我國IMT頻譜規(guī)劃情況,并整理了現(xiàn)在國內(nèi)外主流的IMT系統(tǒng)頻譜需求預(yù)測方法,總結(jié)歸納了各種方法的優(yōu)點和缺點。然后,根據(jù)未來5G系統(tǒng)的關(guān)鍵能力指標(KPI),使用基于KPI分場景的頻譜需求方法計算5G典型場景頻譜需求,結(jié)果顯示未來5G系統(tǒng)的頻譜需求量較大,根據(jù)熱點基站和小基站的部署特點,2030年時6GHz以下頻段5G系統(tǒng)的頻譜需求是2720M,24.25-86GHz頻譜范圍內(nèi)的頻譜需求大約是24.3GHz。緊接著,從我國IMT系統(tǒng)實際密集城區(qū)場景的情況考慮,提出了一種基于Gompertz曲線的頻譜需求預(yù)測方法,從預(yù)測的結(jié)果來看,未來商用5G系統(tǒng)后需要的頻譜量將會受到多種因素的影響,每一種因素的改變,都將引起5G系統(tǒng)的頻譜需求動態(tài)變化。本文通過兩種不同的方法,從不同角度對5G典型場景頻譜需求進行計算,具有便于實現(xiàn)的特點,可以有效地體現(xiàn)2030年時我國5G典型場景的頻譜需求情況,對未來頻譜的規(guī)劃有重大意義。
[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.
