Background Integrated sensing and communication (ISAC) has been envisioned to benefit various emerging applications in the future, with enhanced spectral, energy, and hardware efficiency. One potential scenario is the use of radio frequency identification (RFID) for inventory management in warehouses or retail stores, where low-cost passive RFID tags...

Background Wireless communications systems in 5G and beyond are using high-frequency signals (in the mmWave band in 5G and sub-terahertz bands in 6G and beyond). The large bandwidth available at these high frequencies enable the communication systems to send data at very high rates. However, increasing frequency comes at the expense of lower penetration...
