The perception-assisted predictive handover method in the high-speed railway tunnel scene of the application belongs to the technical field of wireless communication and intelligent transportation, and the steps include: constructing a bistatic communication and perception integrated architecture, establishing a communication and perception signal model considering double selective channels, deducing a lower bound of Cramer-Rao based on joint time delay-Doppler parameter estimation to establish a perception-assisted location prediction model, designing a three-state predictive handover mechanism based on perception information, and proposing a perception-assisted dual deep Q network algorithm, jointly optimizing handover decision, clamp antenna configuration and power allocation. By integrating perception capability into handover decision, the application realizes predictive switching before signal degradation, significantly improving the handover success rate and communication throughput in the high-speed railway tunnel scene.
