基于2.6 GHz+4.9 GHz频段5G双层组网方案的研究

Research on 5G Double Layer Networking Scheme Based on 2.6 GHz+4.9 GHz Band

截止2020年5月底,中国移动已建设开通了1.4×105个5G基站。在投入大量人力和物力建设5G网络后,使得5G基站的整体规模远超其他运营商。但在热点高容量区域,只采用2.6 GHz单频组网覆盖会使5G网络下载速率面临着较大挑战。充分挖掘4.9 GHz频段的潜力,中国移动可采用基于2.6 GHz+4.9 GHz频段的5G双层组网方案,通过载波聚合技术有效提高网络下载速率。此外,利用2.6 GHz+4.9 GHz频段5G双层网络交叉覆盖能有效减少覆盖盲区,提升5G网络上下行容量和覆盖性能。

By the end of May 2020,CMCC has built and opened 1.4×1055G Base Stations.After investing a lot of manpower and material resources to build 5G network,the overall scale of its 5G Base Station has far exceeded that of other operators.However,in the hot high-capacity area,the 5G network download rate with 2.6 GHz single frequency network coverage is facing challenges.By fully tapping the potential of 4.9 GHz frequency band,CMCC can adopt 5G double layer networking scheme based on 2.6 GHz+4.9 GHz frequency band,effectively improve network download rate through carrier aggregation technology,and effectively reduce the coverage blind area by using cross coverage of 5G double-layer network in 2.6 GHz+4.9 GHz band,and improve the uplink and downlink capacity and coverage performance of its 5G network.
