AI Empowered Net-RCA for 6G

In order to realize the vision of connecting everything worldwide, the sixthgeneration (6G) wireless networks are receiving unprecedented attention, and are anticipated to build a bridge to the smart society of the future. Compared with 5G, 6G is expected to boost network spectrum efficiency, offer massive access, improved reliability, and latency, as shown in Table 1. Consequently, future 6G networks are expected to be able to support wireless connections of various emerging applications and massive intelligent devices e.g., extended reality (XR) services, telemedicine and brain-computer interfaces, and deliver low latency and high data rates for different heterogeneous devices. We illustrate the key emerging 6G applications in Fig.1. Specifically, the application types of 6G can be classified as MBRLLC, mURLLC, HCS and MPS [8]. The most representative 6G use cases are presented as follow, the network requirements are shown in Table 2. Holographic Type Communication (HTC): HTC is expected to deliver 3D images from one or multiple source nodes to different destinations. Owing to the extremely large data for recording and reconstructing, HTC requires bandwidth up to Tbps level for transmission.
