Title
Intelligent Base Station Architectures for Resilient, Sustainable, and Green Wireless Communications
Abstract
6G wireless technology is still in its infancy, but it has attracted a lot of attention recently. The International Telecommunication Union (ITU) has recently introduced a framework and overarching goals for the advancement of the terrestrial aspect of International Mobile Telecommunications (IMT) beyond 2030, known as IMT-2030. This framework sets the stage for the development of 6G technology, which aims to achieve unprecedented levels of performance, reliability, security, and sustainability.
In this talk, we will focus on one of the key components of 6G technology: the base stations. We will present a comprehensive overview of the architecture of 6G base stations, informed by trends and obstacles encountered in preceding wireless generations. In particular, we will discuss some of the main challenges that 6G base stations will face, such as dealing with higher frequencies and shorter wavelengths, harnessing the potential of massive MIMO and beamforming technologies for integrated sensing and communication, prioritizing energy efficiency, and managing network density and heterogeneity. Moreover, we will explore some of the emerging opportunities to overcome these challenges, such as AI-driven architectural paradigms, dynamic spectrum sharing strategies, the integration of terrestrial and satellite networks, innovative and unconventional approaches such as aerial base stations or low-altitude platforms like balloons, and the utilization of cutting-edge materials like reconfigurable intelligent surfaces (RIS).
Finally, we will share some insights learned from our prior research projects concerning 6G base stations: (1) Unmanned Aerial Vehicle (UAV) Cellular Base Stations for Robust Wireless Connectivity, (2) Reconfigurable Intelligent Surfaces (RIS) for Environmentally Friendly Wireless Solutions, and (3) Dual Powered Management for Eco-conscious Wireless Operations. These lessons will illustrate some of the practical implications and applications of 6G technology for various domains and scenarios.

Title
A New Motor Drive Concept – Wireless Motor Drive
Abstract
Electric motor drive is a relative mature technology that can interconvert electrical and mechanical energies. Typical electric motor drive relies on physical link to transfer power from electric source to driving load, and vice versa. Wireless power transfer (WPT) is a technology that can transfer electrical energy without any physical wires or physical link. Even though WPT was firstly proposed in around 19th century, due to limitation of available technologies, it has not received much attention until the last few decades. In last few years, a new concept of motor drive, namely wireless motor drive has been explored. By combing the key features of electric motor drive and WPT, wireless motor drive can interconvert energies without physical links.
In this presentation, the background of the wireless motor drives, followed by the working principles of such new technology, will be introduced. The key features, including the pros and cons of this new motor concept, will be revealed. The wireless motor drives should aim to eliminate the control part at the motor side, while it should therefore keep the drive circuit at the transmitter side. Two promising wireless motors, namely the wireless DC motors and wireless AC motors, will be taken as example for discussions. Finally, research opportunities and technological challenges of this new motor drive concept will be elaborated.
