Integrated Sensing and Communication Meets Smart Propagation Engineering: Opportunities and Challenges
CoRR(2024)
摘要
Both smart propagation engineering as well as integrated sensing and
communication (ISAC) constitute promising candidates for next-generation (NG)
mobile networks. We provide a synergistic view of these technologies, and
explore their mutual benefits. First, moving beyond just intelligent surfaces,
we provide a holistic view of the engineering aspects of smart propagation
environments. By delving into the fundamental characteristics of intelligent
surfaces, fluid antennas, and unmanned aerial vehicles, we reveal that more
efficient control of the pathloss and fading can be achieved, thus facilitating
intrinsic integration and mutual assistance between sensing and communication
functionalities. In turn, with the exploitation of the sensing capabilities of
ISAC to orchestrate the efficient configuration of radio environments, both the
computational effort and signaling overheads can be reduced. We present
indicative simulation results, which verify that cooperative smart propagation
environment design significantly enhances the ISAC performance. Finally, some
promising directions are outlined for combining ISAC with smart propagation
engineering.
