Abstract

5G New Radio (NR) incorporates numerous beam-based novel features such as beam management procedures for selecting the best serving gNB beam, recovery from beam failures, beam-based inter-cell mobility support and advanced UEs with multiple directional panels. In this paper, we study the joint performance of all these techniques for a macro cellular scenario at 28 GHz with special emphasis on how the UE antenna design influences the system-level performance. It is shown that the full benefits of 5G can be delivered with the introduction of multiple directional antenna panels at the UE side. We also introduce a mechanism for controlling the UE antenna panel switching. Our results from advanced dynamic system-level simulations indicate excellent performance with handover failure rates on the order of 0.01-0.03%, and beam failure rates at 0.04%, for UE speeds as high as 60 km/h. The median SINR gain of using four directional antenna panels at the UE equals 6 dB as compared to Omni UEs.

不同多面板天线器件型号毫米波5G系统的系统级分析

5G新无线电(NR)融合了许多基于波束的新功能，例如用于选择最佳服务gNB波束的波束管理程序、波束故障恢复、基于波束的小区间移动性支持以及带有多方向面板的先进终端。在本文中，我们研究了所有这些技术在28 GHz宏蜂窝场景下的联合性能，特别强调了UE天线设计如何影响系统级性能。事实证明，通过在终端侧引入多向天线面板，可以充分发挥5G的优势。我们还介绍了一种控制终端天线面板切换的机制。我们的先进动态系统级仿真结果表明，当UE速度高达60 km/h时，切换故障率为0.01-0.03%，波束故障率为0.04%，性能优异。在终端使用四个定向天线面板的中位信噪比增益等于6 dB。
