T8: Signals and Waveforms for Sustainable Multifunctional 6G Networks and Beyond

Organizer: Christos Masouros, University College London, UK

Abstract: The future Global cellular infrastructure will underpin smart city applications, urban security, infrastructure monitoring, smart mobility, among an array of emerging applications that require new network functionalities beyond communications. Key network KPIs for 6G involve Gb/s data rates; cm-level localization; μs-level latency; Tb/Joule energy efficiency. Future networks will also need to support the UN’s Sustainable Development Goals to ensure sustainability, net-zero emissions, resilience and inclusivity. The multifunctionality and the net-zero emissions agenda necessitate a redesign of the signals and waveforms for 6G and beyond. In this tutorial, we will first explore a recent research direction involving symbol-level precoding (SLP) approaches that treat interference as a useful resource in multi-antenna communication systems. These have been shown to offer orders of magnitude savings in power consumption, over a range of communication scenarios. The second part of the tutorial will focus on enabling the multi-functionality of signals and wireless transmissions, as a means of hardware reuse and carbon footprint reduction. We will overview the emerging area of integrated sensing and communications (ISAC), that is a paradigm shift that enables a both sensing and communication functionalities from a single transmission, a single spectrum use and ultimately a common infrastructure. With the rising demand for sustainability and resilience from the network infrastructure, the above technologies are becoming essential building blocks of the wireless network.
