Abstract

With the recent advances of wireless communications and signal processing techniques, the capability of wireless sensing would be integrated with communications, which benefits from dedicated communications and sensing hardware and enables new waveform design, transmission strategies, and resource allocation. In particular, a radio emission could simultaneously be used for conveying communication data as well as extracting environmental information from the scattered echoes. It is expected that this emerging paradigm can significantly improve the energy and hardware efficiencies of next generation cellular network and can enable a greener network. In practice, the integration may happen on different levels, via the same hardware architecture, the same spectrum resources, or via a unified signal processing framework such that different kinds of resource efficiency are achieved. This type of research is normally referred to as Integrated Sensing and Communications (ISAC).
