Abstract

With the rapid development of 5G communication technology, people's research and exploration of 6G communication have begun. The goal of 6G communication is to achieve higher data rates, lower latency, and wider connectivity ability, which will further promote the development and application of communication technology. However, with the rapid development of wireless communication, existing spectrum resources have become strained, requiring finding new spectrum resources to support higher data rates and more connected devices. To meet these requirements, the communication-sensing integrated architecture becomes one of the key technologies, and it also becomes a complex problem. This paper aims to introduce the research progress of communication and sensing integration architecture and key technologies for 6G, including sensing networks, data fusion, intelligent decision-making, and so on, and to look forward to the future development direction. These studies and explorations will also provide support and help for the development of 6G communication to a certain extent, and promote the further development of communication technology.
