5G垂直行业上行网络需求及覆盖增强技术探讨
摘要
当前5G可用频谱均在2G以上
上行覆盖受限严重。为进一步满足2B垂直行业需求
进一步提升网络的可靠性
必须通过有效的技术方案进行上行覆盖增强
提升5G上行覆盖能力。本文首先重点分析了双连接、SUL和CA这3种5G上行覆盖增强关键技术
然后对比分析了这3种关键技术的优劣势
为后续5G规模部署提供参考。
Abstract
At present
5G available spectrum is above 2G
and uplink coverage is severely limited. In order to further meet the needs of 2B vertical industry and further improve the reliability of the network
it is necessary to enhance the upstream coverage through effective technical solutions to improve the 5G upstream coverage capacity. Firstly
this paper focuses on the analysis of the key technologies of dual connection
SUL and CA
and compares the advantages and disadvantages of these three key technologies
so as to provide reference for the subsequent 5G scale deployment.
