I. Introduction
The advent of integrated sensing and communication (ISAC) marks a transformative breakthrough for the realm of 6 G networks [1]. While radar sensing and wireless communications have traditionally progressed independently, the emergence of joint communication and sensing now brings forth a game-changing paradigm, presenting unprecedented opportunities to revolutionize spectrum efficiency, reduce hardware cost and power consumption, and redefine how networks perceive and interact with their surroundings. Given this context, ISAC has attracted significant research interest and attention from both academic and industrial sectors. Indeed, various scenarios and challenges have been explored. These include, dual-functional radar and communication (DFRC) [2], unmanned aerial vehicles [3], waveform design [4], beamforming design [5], security [6], [7], and intelligent reflecting surfaces [8], [9].
