Reflections on Integrated Sensing and Communication
(China Mobile Research Institute, Beijing 100053, China)
Abstract: The integrated sensing and communication (ISAC) has rich technical connotations and application scenarios, becoming a hot research topic in 6G. The similarities and differences between the technical characteristics of communication and radar are analyzed. The theory, technology, and engineering challenges of the ISAC from the perspective of network sensing function are discussed. The research suggestions on the joint design of ISAC and semantic communications are proposed, as well as the suggestions for future network deployment and operation in terms of spectrum, product form, and private sensing network. It is believed that the standardization of ISAC in the 5G enhanced version and 6G system will certainly promote the integrated development of communication industry and radar industry.
Keywords: 6G; integrated sensing and communication; private sensing network
