Integrated sensing and communications (ISAC) has emerged as one of the key usage scenarios for 6G networks. This talk discusses the recent advancements in ISAC technology, with particular emphasis on three key aspects including fundamental performance tradeoffs, large-scale network cooperation, and sensing-assisted communications. The discussion begins with an analysis of the fundamental limits in the Cramér-Rao bound (CRB) versus rate tradeoff for ISAC systems employing multiple antennas, along with practical approaches for waveform and beamforming design. Subsequently, we present collaborative networking solutions involving both base stations and intelligent reflecting surfaces (IRS) to facilitate ISAC implementation across large networks. Additionally, we introduce innovative sensing-assisted channel estimation and prediction techniques that combine model-based and data-driven approaches. Finally, we discuss promising research directions to motivate future work.
