对移动的数据不断增长的需求需要一种能够承受5G及以上多Gbps流量要求的传输网络架构。为了满足这种前所未有的需求，正在进行研究以将太赫兹（THz）通信结合到未来的移动的网络中。在本文中，我们考虑了城市环境，并评估了在具有功能分裂的分散式5G网络架构中，中央单元（CU）和分布式单元（DU）之间的传输网络的THz无线中途链路的可行性。我们的目标是研究在140 GHz的中途链路的可行性，最大限度地减少所需的CU的数量，以服务于所有的DU。为此，我们定义了几种策略，选择CU和DU节点，以确定峰值数据速率，可以支持在每个链接之间的CU和DU。我们的数值结果的基础上，射线跟踪表明，无线链路在140 GHz的3GPP选项2作为高层分裂（HLS）是一个很有前途的技术，用于中途运输网络。
The ever-growing demand for mobile data necessitates a transport network architecture that can withstand the 5G-and-beyond multi-Gbps traffic requirements. To cater for such unprecedented demand, studies are being conducted to incorporate TeraHertz (THz) communications in future mobile networks. In this paper, we consider an urban environment and evaluate the feasibility of THz wireless midhaul links for the transport networks between the Central Units (CU) and Distributed Units (DU) in a disaggregated 5G network architecture with functional splits. Our goal is to study the feasibility of midhaul links at 140 GHz by minimizing the number of required CUs to serve all the DUs. To this end, we define several policies for selecting CU and DU nodes in order to determine the peak data rate that can be supported over each link between a CU and DU. Our numerical results based on ray-tracing suggest that wireless links at 140 GHz with 3GPP option 2 as High Layer Split (HLS) represents a promising technology for midhaul transport networks.
