T8: Wireless Information and Energy Transfer in the Era of 6G Communications

Abstract: Conventional energy-constrained wireless systems such as sensor networks are powered by batteries and have limited lifetime. Wireless power transfer (WPT) is a promising technology for energy sustainable networks, where terminals can harvest energy from dedicated electromagnetic radiation through appropriate electronic circuits.

The integration of WPT technology into communication networks introduces a fundamental co-existence of information and energy flows; radio-frequency signals are used in order to convey information and/or energy. The efficient management of these two flows through sophisticated networking protocols, signal processing/communication techniques and network architectures, gives rise to a new communication paradigm called wireless powered communications (WPC).

In this tutorial, we discuss the principles of WPC and we highlight its main network architectures as well as the fundamental trade-off between information and energy transfer. Several examples, which deal with the integration of WPC in modern communication systems, are presented. Specifically, we study some fundamental network structures such as the MIMO broadcast channel, the interference channel, the relay channel, the multiple-access channel, and ad-hoc networks. The integration of WPC in 6G and beyond is analyzed and discussed through the use of tools from stochastic geometry. Future research directions and challenges are also pointed out.
