Abstract
Integrated Sensing and Communication (ISAC) is pivotal to the development of Sixth Generation (6G) wireless systems, seamlessly merging communication and sensing capabilities to optimise both spectral and hardware resources. The incorporation of Orbital Angular Momentum (OAM) presents a significant opportunity to enhance ISAC by boosting spectral efficiency and facilitating advanced spatial multiplexing techniques. This paper explores the synergies between OAM and other state-of-the-art technologies, including Millimetre-Wave (mmWave)/Terahertz (THz) communications, ultra-massive MIMO (umMIMO), and Reconfigurable Intelligent Surfaces (RIS). We aim to explore the collaborative potential of OAM-enabled ISAC in conjunction with emerging wireless technologies, positioning them within the broader landscape of 6G communications and beyond.
