Abstract

Digital twin (DT) technologies have been increasingly important and useful for wireless communications. In particular, to support soaring wireless traffic with limited frequency spectrum assigned to legacy cellular systems, efficient operation and management of wireless resources as well as preemptively prediction of future spectrum usage are crucially important. For such purpose, DT networks for current fourth-generation (4G) and fifth-generation (5G) networks are constructed in this paper, by simultaneously utilizing measurement data from user equipments (UEs) and geographical information and characteristics of 4G and 5G base stations (BSs) within a specific observation area. Representative case studies are provided to demonstrate the usefulness of DT enabled cellular network management and prediction. As a real or near real time DT application, the impact and benefit of dual connectivity and dynamic spectrum sharing between 4G and 5G networks are analyzed. As a non-real time DT application, long-term improvement of 5G networks such as densification of BSs, implementation of advanced multiple input and multiple output technologies, and assignment of additional spectrum are analyzed and compared.

支持数字孪生的蜂窝网络管理和预测

数字孪生（DT）技术对无线通信的重要性和实用性与日俱增。特别是，在传统蜂窝系统频谱有限的情况下，要支持急剧增长的无线通信流量，无线资源的高效运营和管理以及对未来频谱使用情况的预先预测至关重要。为此，本文通过同时利用特定观测区域内用户设备（UE）的测量数据以及 4G 和 5G 基站（BS）的地理信息和特征，构建了当前第四代（4G）和第五代（5G）网络的 DT 网络。本文还提供了具有代表性的案例研究，以展示支持 DT 的蜂窝网络管理和预测的实用性。作为真实或接近实时的 DT 应用，分析了 4G 和 5G 网络之间双连接和动态频谱共享的影响和益处。作为非实时 DT 应用，分析和比较了 5G 网络的长期改进，如 BS 的密集化、先进的多输入和多输出技术的实施以及额外频谱的分配。
