摘要

随着AR/VR等大流量需求业务的剧增，提高单用户峰值速率势在必行。研究了载波聚合、补充上行和双连接等可以提升单用户峰值速率性能的多频段联合传输技术在不同协议版本的基本原理，分析了不同技术对网络的部署要求，尤其针对不共BBU或不共RRU场景做了定性的性能分析。后续可以开展定量分析或测试验证工作进一步印证定性分析的正确性。计算了不同技术对应的上下行峰值速率和边缘速率，包括不同协议版本的性能对比。最后介绍了不同技术的产业现状。

Abstract

With the rapid growth of large traffic demand services such as AR/VR

it is imperative to increase the peak rate of single user.The basic principles of multi-band joint transmission technology in different protocol versions were mainly studied

such as carrier aggregation

supplementary uplink and dual connectivity

which could improve the performance of single user peak rate.Then the deployment requirements of different technologies to the network were analyzed

especially for the non-co-BBU or non-co-RRU scenarios to do qualitative performance analysis

subsequent quantitative analysis or test verification will further verify the accuracy of qualitative analysis.After that

the upstream and downstream peak rate and edge rate corresponding to different technologies were calculated

including performance comparison of different protocol versions.At last

the industry status quo of different technologies was introduced.
