Abstract: For the sixth generation mobile communication system (6G), the integrated sensing and communication technology, as one of the key technologies of 6G, will help realize the development needs of 6G digitization, networking and intelligence. Interference management in the integrated communication and sensing system faces many challenges. The connotation not only includes the mutual interference cancellation when the sensing subsystem and the communication subsystem cooperate to realize the integrated communication and sensing function, but also includes more flexible and efficient interference avoidance and interference utilization methods, which reflects the development concept of green communication. First describes the necessity of interference management in the integrated system of sensing and communication. Then, the interference elimination methods are reviewed respectively from three paradigms of integrated system implementation and the feasible methods to realize the vision of interference avoidance and interference are put forward follow. Finally, we conclude the paper and identify some open problems in this field.

Key words: integration of wireless sensing and communication, interference management, resource sharing, functional integration
