AI总结:

本文研究7-24 GHz上中频段6G网络与现有业务共存的潜力与挑战,通过射线追踪评估表明FR-3在覆盖和带宽上优于FR-2和FR-1,并提出基于Open RAN的动态频谱与服务共享网络架构。

摘要:

跨越7至24 GHz的上中频段在未来第六代(6G)网络的大带宽与良好传播环境之间取得了良好的平衡。然而,上中频段的无线网络将需要共享频谱,并与各种现有业务安全共存,包括无线电定位、固定卫星业务以及地球探测与传感。本文迈出了理解7至24 GHz之间蜂窝系统潜力与挑战的第一步。我们重点关注与现有业务共存的使能技术与政策。我们考虑了由可编程和自适应蜂窝网络实现的动态频谱共享解决方案,同时也探讨了利用蜂窝基础设施提供现有业务的可能性。我们的综合分析采用射线追踪技术,并考察了现实世界的城市场景,以评估吞吐量、覆盖权衡以及对现有业务的潜在影响。我们的研究结果突出了FR-3在覆盖和带宽方面分别优于FR-2和FR-1的优势。最后,我们讨论了基于Open RAN的网络架构,旨在实现动态频谱与服务共享。

英文摘要:

The upper midband, spanning 7 to 24 GHz, strikes a good balance between large bandwidths and favorable propagation environments for future 6th Generation (6G) networks. Wireless networks in the upper midband, however, will need to share the spectrum and safely coexist with a variety of incumbents, ranging from radiolocation to fixed satellite services, as well as Earth exploration and sensing. In this paper, we take the first step toward understanding the potential and challenges associated with cellular systems between 7 and 24 GHz. Our focus is on the enabling technologies and policies for coexistence with established incumbents. We consider dynamic spectrum sharing solutions enabled by programmable and adaptive cellular networks, but also the possibility of leveraging the cellular infrastructure for incumbent services. Our comprehensive analysis employs ray tracing and examines real-world urban scenarios to evaluate throughput, coverage tradeoffs, and the potential impact on incumbent services. Our findings highlight the advantages of FR-3 over FR-2 and FR-1 in terms of coverage and bandwidth, respectively. We conclude by discussing a network architecture based on Open RAN, aimed at enabling dynamic spectrum and service sharing.
