HIGH-SENS} exploits the benefits of frequency diversity in multiband integrated sensing and communications (ISAC) systems toward attaining high-resolution sensing capabilities in 6G with the best trade-off between communication and sensing functionalities. By investigating and analyzing different properties of frequencies in the frequency range (FR3, 7-24 GHz), we will provide novel algorithms and frameworks that exploit large aperture gains and the different merits of different frequency bands while considering the impact of synchronization errors. Multiband ISAC systems may be promising to offer effective sensing-based services and applications, but effective signal processing techniques and fundamental limits are still required to exploit the benefits of cooperation over a large frequency aperture. Thus, critical questions to be answered with HIGH-SENSE are: How to strategically exploit multiple frequency bands to improve sensing performance with minimal impact on the communication functionality? What can we learn from the correlations of non-consecutive bands to exploit diversity in multiband ISAC systems? Which are the limitations? What is the impact of phase distortions on multiband ISAC and how to circumvent this?
