摘要:

5G在数字配电网领域的核心价值在于发挥5G的超高可靠、低时延技术优势,为配电网涉控业务提供高可靠、低时延的通信。为了系统地提供配电网5G通信时延与可靠性理论分析方案,结合数字配电网业务给出了配电网5G通信典型架构,深入分析了针对配电网5G通信的时延模型,针对国内四大运营商5G帧结构逐一进行了端到端时延分析,并通过5G链路级仿真了3GPP Rel-15和Rel-16的5G可靠性数值,提出了配电网5G通信的时延与可靠性联合分析方法。

Abstract:

The core value of 5G in the field of digital distribution network is to give play to the technical advantages of 5G in ultra-high reliability and low latency, and provide high reliability and low latency communication for the control related business of distribution network.In order to provide a systematic theoretical analysis scheme for the latency and reliability of 5G communication deployment applications in the distribution network, a typical architecture of 5G communication in the distribution network in combination with digital distribution network services was given, the latency model for 5G communication in the distribution network was deeply analyzed.The end-to-end latency analysis for 5G frame structures of four operators in China was conducted with 5G reliability values of 3GPP Rel-15 and Rel-16 through 5G link level simulation.At last, a joint analysis method of time latency and reliability of 5G communication in distribution network was proposed.

Key words: 5G, digital distribution network, latency, reliability, URLLC
