5G超级上行技术应用探讨

Discussion on the Application of 5G Super Uplink Technology

随着5G网络的完善及多样化业务的开展,NR 3.5G在上行覆盖、上行带宽方面的固有缺陷以及时延问题已经成为限制部分业务开展的瓶颈。超级上行技术在对载波聚合、上行链路补充技术改良的基础上,有效地提升了上行带宽,并缩短时延。在介绍技术原理的前提下,对超级上行技术与其他两种技术进行优劣势比较,并介绍了该技术的应用场景及部署方式,最后通过测试验证了该技术的有效性。

With the improvement of 5G network and the development of diversified services,the inherent defects of NR 3.5G in uplink coverage,uplink bandwidth and delay have become the bottleneck restricting the development of some services.Based on the improvement of carrier aggregation and uplink supplementary technology,super uplink technology effectively improves the uplink bandwidth,coverage and shortens the delay.On the premise of introducing the technical principle,this paper compares the advantages and disadvantages of this technology with the other two technologies,introduces the application scenario and deployment mode of this technology,and finally proves the effectiveness of this technology through test data.
