Day 1 : 30 January 2023

Over four decades, wireless networks continue to play a fundamental role in data transmission and communicating information between users. Wireless networks have gone through five large-scale revolutions, resulting in 1G, 2G, 3 G, 4G, and most recently 5G networks. In 1G and 2G, voice and text were possible. In 3G and 4G, pictures and video …

6G networks, currently only existing as concepts, are envisioned as portals to a fully digitized society. In this talk, we give a short overview of main 6G trends (such as disaggregation, joint communication and sensing, as well as integration with aerial networks). We also assess them with respect to sustainability and the sustainable development goals.

With the current rollout of 5G, the focus of the research community is shifting towards the design of the next generation of mobile systems, e.g., 6G mobile networks. Non-orthogonal multiple access (NOMA) has been recongized as an essential enabling technology for the forthcoming 6G networks to meet the heterogeneous demands on low latency, high reliability, massive connectivity, improved fairness, and high throughput. The principle of NOMA is to encourage users for spectrum sharing, where multiple users are served in the same resource block, such as a time slot, subcarrier, or spreading code. The aim of this talk is to provide an overview of the latest research results and innovations in NOMA technologies as well as their emerging applications, including ambient IoT, terahertz (THz) communications, mobile edge computing (MEC), age of information (AoI), etc. Future research challenges regarding NOMA in B5G and 6G are also presented.

Traditional single-input single-output (SISO) and multiple-input multiple-output (MIMO) information theory adopt spatially discrete modeling, which mismatches the continuous nature of the underlying electromagnetic (EM) fields. Therefore, it is essential to analyze the information-carrying capability of continuous EM fields, which motivates the research of EM information theory (EIT). In this talk, we investigate the basics and …
