Communication and Computing Integration: Characteristic of Computing Power Network towards 6G

Mobile communication has evolved from 4G to 6G, and each stage has its unique computing form. In the 4G era, cloud computing empowered the rapid rise of mobile Internet. In the 5G era, edge computing supported the stringent requirement of “data never leaves the field” in industrial internet and other industry applications. In terms of network architecture and business types, 6G puts forward more refined requirements for computing power. The relationship between computing power and communication environment becomes closer, and the integration of computation and communication becomes a new technical development trend. This paper introduces the current research status of 6G and computing power network (CPN). And it analyzes the requirements of 6G architecture and business for computing power, and proposes the characteristic of computing power network towards 6G - Communication and Computing Integration. Finally, it introduces how communication and computing resources can be integrated from five aspects: channel, device, protocol, control and service. The article summarizes the key issues that need to be considered in the overall architecture design of 6G in terms of the characteristic of integration of computation and communication.
