本文评估了6G黄金频段FR3中波束管理的开销，发现实现高稳定移动吞吐量需大量波束管理工作，且FR3与FR2的非相邻波束切换速率相当。
AI中文摘要：
频率范围3（FR3），即7.125-24.25 GHz，被视为6G网络的“黄金频段”，其传播特性比FR2更具优势，同时比FR1提供更宽的带宽以支持高数据速率应用。在FR3网络部署中复用现有FR1基础设施，要求gNodeB（gNB）采用天线阵列并执行波束管理，而这在FR2中已被证明具有挑战性。本文对FR3城市网络中的波束管理开销进行了广泛研究和表征，具体包括：波束对齐灵敏度、定向链路机会数量、gNB切换和波束切换速率，以及波束转向距离。我们的结果表明，要实现高且稳定的移动吞吐量，需要在FR3频段上进行大量的波束管理工作。尽管由于波束较宽，低频段的波束跟踪要求不那么严格，但在FR3和FR2中，切换到非相邻波束的速率相对相当。
英文摘要：
Frequency Range 3 (FR3), 7.125-24.25 GHz, regarded as the "golden band" for 6G networks, has less challenging propagation characteristics than FR2 while offering much wider bandwidth for high data rate applications than FR1. Reusing existing FR1 infrastructure for FR3 network deployments requires gNodeBs (gNBs) to employ antenna arrays and perform beam management, which has proven challenging at FR2. In this paper, we extensively study and characterize the beam management effort in an FR3 urban network, in terms of: beam alignment sensitivity, number of directional link opportunities, gNB handover and beam switch rates, and beam steering distance. Our results show that achieving a high and stable mobile throughput requires significant beam management effort across FR3 bands. While the beam tracking requirements are less stringent at the lower frequencies due to wider beams, the beam switching rate to a non-adjacent beam is relatively comparable at FR3 and FR2.
