摘要: 隨著移動(dòng)通信網(wǎng)絡(luò)的不斷發(fā)展,運(yùn)營商擁有高中低不同的頻段資源,無線電頻段資源是寶貴的戰(zhàn)略資源,如何合理高效地利用頻譜資源是目前運(yùn)營商考慮的首要問題。在5G NR 2.1 GHz和NR 3.5 GHz頻段的覆蓋性能、業(yè)務(wù)承載等方面對(duì)比分析的基礎(chǔ)上,提出了不同場景下的組網(wǎng)建議和多載波間移動(dòng)策略建議,為后續(xù)5G網(wǎng)絡(luò)建設(shè)提供重要依據(jù)。

Abstract: With the continuous development of mobile communication network, operators have different frequency band resources at high, middle and low levels. Radio frequency band resources are valuable strategic resources, and how to use spectrum resources reasonably and efficiently is the primary issue that operators consider at present. Based on the comparative analysis of the coverage performance and service bearing of 5G NR 2.1 GHz and NR 3.5 GHz bands, this paper puts forward suggestions for networking and inter-carrier mobile strategy in different scenarios, providing an important basis for the subsequent construction of 5G networks.
Key words : G;NR 3.5 GHz;NR 2.1 GHz;multi-bands network construction;multi carrier strategy

5G網(wǎng)絡(luò)共建共享為移動(dòng)網(wǎng)絡(luò)發(fā)展和運(yùn)營帶來機(jī)遇的同時(shí),也帶來諸多技術(shù)層面的挑戰(zhàn)。以中國聯(lián)通和中國電信5G共建共享網(wǎng)絡(luò)為例,目前兩家運(yùn)營商已經(jīng)在3.5 GHz頻段進(jìn)行了網(wǎng)絡(luò)共建共享,同時(shí)又分別在2.1 GHz頻段擁有25 MHz和20 MHz帶寬。2.1 GHz和3.5 GHz頻段在5G網(wǎng)絡(luò)中如何合理高效地利用是目前運(yùn)營商考慮的重要問題。本文在對(duì)5G NR 2.1 GHz和3.5 GHz頻段的覆蓋性能、業(yè)務(wù)承載等方面進(jìn)行對(duì)比分析的基礎(chǔ)上,對(duì)不同場景下的組網(wǎng)建議和載波間移動(dòng)策略進(jìn)行探索,旨在為后續(xù)5G雙頻段組網(wǎng)規(guī)劃提供重要依據(jù)。
