Abstract

In this chapter, we first introduce the basics of ISAC and RIS, and discuss the motivations of RIS-enabled ISAC in 6G. Then, we present the potential application scenarios of RIS-enabled ISAC and provide its fundamentals, including the RIS response model, the signal model, as well as the channel model. Finally, research on RIS-enabled ISAC is reviewed.

Notes

  1. 1.

    OFDM is adopted in the RIS-enabled ISAC system because it is widely used in the communication systems and is also able to be implemented in the radar system.

  2. 2.

    Narrowband scenario is considered where the bandwidth is much smaller than the carrier frequency (i.e., \(B\ll f_c\)) and the wavelength is approximately constant over the entire bandwidth.

  3. 3.

    We consider the full-duplex BS that the transmitting and receiving antennas work simultaneously without self-interference.
