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.
