摘要: 為確定在31.8 GHz~33.4 GHz頻段為移動通信做出附加主要業(yè)務劃分的可行性,,對該頻段第五代移動通信(5G)系統(tǒng)與無線電規(guī)則頻率劃分表中的主要業(yè)務無線電導航業(yè)務間的同頻共存問題進行了系統(tǒng)間同頻共存分析。采用最新的5G系統(tǒng)技術參數(shù)以及典型的無線電導航業(yè)務系統(tǒng)參數(shù),,通過仿真5G系統(tǒng)基站對無線電導航業(yè)務干擾功率密度,,計算不同場景下5G系統(tǒng)基站對無線電導航業(yè)務的干擾概率。仿真結果表明,,5G系統(tǒng)基站對無線電導航業(yè)務的同頻干擾概率較大,,因此,,不建議在該頻段引入移動通信系統(tǒng)。

Abstract: In order to determine the feasibility of additional allocations to the mobile services on a primary basis in the frequency band 31.8~33.4 GHz, this paper analyzes the electromagnetic compatibility between the 5th Generation(5G) international mobile telecommunications system and radionavigation service, which is the principal services according to regulations on the radio frequency allocation in the frequency band. The paper simulates the aggregated interference from the 5G base stations, adopts the latest parameters and the typical characteristics of radionavigation service, and calculates the interference probability in different scenarios. The simulation results show that the 5G base stations may cause harmful interference to radionavigation service, so it is not recommended to introduce mobile communication system in this frequency band.
Key words : 5G system;radionavigation service,;co-existence analysis

31.8~33.4 GHz是世界無線電大會2019(WRC-19)議題1.13的重點關注頻段之一[1],。該議題主要目的是為國際移動通信(IMT)確定頻段,包括可能在24.25~86 GHz之間的部分頻段為移動業(yè)務做出附加主要業(yè)務劃分,,以實現(xiàn)IMT在2020年及之后的未來發(fā)展,。該項研究涉及全球5G毫米波頻段規(guī)劃,目前主要是考慮5G系統(tǒng)與各頻段現(xiàn)有業(yè)務的電磁兼容性問題,。
根據無線電規(guī)則,,31.8~33.4 GHz頻段目前已經劃分給作為主要業(yè)務的無線電導航等業(yè)務,主要使用者是無線電導航機載雷達,。此類雷達系統(tǒng)裝置在全球的航空器上,,用于地面繪圖、氣象避險,、為在惡劣條件下實施精確空投校準機載導航系統(tǒng),;并向飛行員提供數(shù)據,以降低惡劣氣象條件下著陸階段的決策高度,。這是一種安全業(yè)務,,需要保證其不遭受有害干擾[2]。
本文采用最新的5G通信系統(tǒng)參數(shù)和典型的無線電導航雷達參數(shù),,仿真計算5G系統(tǒng)基站對無線電導航業(yè)務的干擾,,對兩系統(tǒng)間的同頻共存進行詳細分析研究,以確定在該頻段為IMT業(yè)務做出附加主要業(yè)務劃分的可行性,。
