Abstract: Integrated sensing and communication(ISAC) is regarded as a core enabling technology for 6G networks.By sharing spectrum and hardware,it achieves the deep integration of communication and sensing.This paper systematically reviews ISAC applications,and reveals the evolution process of the technology from “separate coexistence” to “deep integration” from five dimensions:waveform design,system architecture,security mechanisms,artificial intelligence(AI) empowerment,and integrated sensing,communication and computation.Additionally,it explores multiple core challenges in current researches.Finally,the paper innovatively proposes four potential development directions:achieving near-field multipath spatiotemporal focusing through time reversal and reconfigurable intelligent surface,driving endogenous intelligence of communication-sensing-computing with counterfactual causal reasoning,establishing a dynamic trust evaluation mechanism based on zero-trust endogenous security,and building cross-medium unified channel model to support full-domain sensing and communication coverage.This work aims to provide valuable reference for advancing ISAC technology from theoretical breakthroughs to practical deployment in 6G networks.

Key words: Integrated sensing and communication, Time reversal, Counterfactual causal reasoning, Endogenous security, Cross-medium
