Summary: This paper proposes a DT architecture for THz wireless networks, which maps a physical network in the THz band into a virtual DT network and represents the DT network as a graph structure. It provides a THz channel model and proposes a resource management problem with weighted mean rate as the optimization objective, which is transformed into a graph optimization problem. Based on this, a distributed message propagation algorithm is proposed, which uses the graph neural network to provide a solution. Simulation results show that the proposed scheme improves the weighted mean rate of the DT network for the THz band and outperforms the benchmark methods. It is also proved that the proposed distributed message propagation algorithm is scalable and can maintain good performance under different conditions.

Summary: Sub-terahertz and terahertz-band communication technologies ranging from 100 GHz to 10 THz will be necessary for future wireless communication networks beyond 6G. While progress has been made in terahertz device technology for personal and local area networks, longer communication distances are needed to fully utilize the capacity of sub-terahertz and terahertz wireless links. In this study, we demonstrate a multi-kilometre and multi-gigabit-per-second link operating at 210-240 GHz using on-chip power-combining frequency multiplier designs and tailored software-defined ultrabroadband digital signal processing.
