6G is expected to be an end-to-end (E2E) information processing system, whosecore function will be extended from information delivery to information acquisition, information delivery and information computing, to support the emerging services, such as AI services, immersive services and digital twin services. The native sensing, enhanced communication and native computing will be the features of 6G, and the integration of sensing, communication and computing is the development trend of 6G. The integration of sensing, communication and computing is an E2E information processing framework, where information delivery will be performed along with information acquisition and information computing. It can be divided into function cooperation, function fusion and function reconfiguration.In traditional information service architecture, terminal is responsible for sensing.Network is responsible for communication, and cloud is responsible for computing.
The integration of sensing, communication and computing is addressed in terms of cooperation of cloud, network, edge and terminal. Actually, cloud services, edge computing, network slicing, non-public network and internet of vehicles (IoV) have introduced such cooperation capabilities. Furthermore, the concept of multifunctional radio has been proposed according to the integration of sensing, communication and computing, where the air interface extends its core function from wireless access and transmission to wireless sensing, positioning, synchronization, and computing.
