Abstract

Facing the demand for interconnectivity sensing of three-dimensional coverage for the sixth-Generation mobile communication (6G) networks and the spectrum scarcity issue caused by the widespread access of wireless devices, the multi-dimensional expanded Integrated Sensing and Communication (ISAC), based on Unmanned Aerial Vehicles (UAV) and Intelligent Reflecting Surfaces (IRS), is capable of achieving synergistic communication and sensing functions in the three-dimensional network space. This can effectively enhance spectrum efficiency, hardware resource utilization, and align with the wireless network vision of 6G Internet of Everything. This paper provides an overview of the architecture for the 6G multi-dimensional expanded ISAC. Firstly, it summarizes the theoretical foundations of the 6G network vision and ISAC networks, and the application scenarios, development trends, and performance indicators of multi-dimensional expanded ISAC based on UAV and IRS are discussed. Then, it investigates the potential applications of 6G key technologies, such as ultra-massive multiple-input and multiple-output antenna, terahertz, simultaneous wireless information and power transfer, artificial intelligence, covert communication, and active IRS, in multi-dimensional expanded ISAC networks based on UAV and IRS. Finally, the future development direction and key technical challenges of 6G multi-dimensional expanded ISAC sre prospected.
