5G用户体验速率优化方法研究

Research on the Optimization Method of 5G User Experience Rate

2019年是5G商用元年,伴随着商用终端发布,基于商用终端的峰值调测需求增多,展示5G大带宽场景下,相对于4G的体验速率10倍以上的直观感受,因此急需峰值速率优化指导.本文从原理上出发介绍5G速率计算的原理,调度次数乘以TBSize,再除去误码率,即为单位时间内信道传输的数据量.影响调度、资源利用率和误码率的关键因素,从端到端梳理分析策略和应对方案,总结出端到端排查要素.最终在实际验证中,取得极大的速率优化提升幅度,实现从原理出发到实际落地卓见成效的预期.

2019 was the first year of commercial use of 5G.With the release of commercial terminals,there’s a demand for peak commissioning based on commercial terminals.This diagram shows the 5G bandwidth scenario.The peak rate is 10 times higher than that of the 4G.Therefore,the peak rate optimization guide is urgently needed.This paper introduces the principle of 5G rate calculation.Grant times multiplied by TBSize.then remove the bit error rate.That is,the amount of data transmitted over the channel in a specified period of time.Key factors affecting granting,resource utilization,and BLER.To analyze the strategies and countermeasures.Summarize the E2E check elements.Finally,in the actual verification,greatly improved rate.Achieve the expected results from the principle to the actual implementation.
