We have released the 47th episode of the Wireless Future podcast. It has the following abstract:
Almost every 6G-related keynote speech at scientific conferences focuses on ISAC: Integrated sensing and communications. In this episode, Erik G. Larsson and Emil Björnson discuss how sensing and communication technologies have been developed separately in the past but are built on similar yet distinctly different principles. The conversation covers different integration levels, beamforming implementations, fundamental tradeoffs, alternative waveforms, and the most important question: What would ISAC be used for if it becomes widely available in 6G networks?

Interesring as always!
ISAC in 6G also involves the UE, which seems to be a tough nut to crack. What is your take on that?
I think it will mainly be the base stations that perform sensing, as their transmit power is higher and have larger computational resources at the receiver side.
Sensing often refers to having targets that are passive, but if we want to track a UE, then we can use the signal that they transmit for such purposes. Algorithms like the MUSIC algorithm can use arbitrary signals for sensing and localization.
