# Implanting Intelligence in 5G Mobile Networks--A Practical Approach
## 4 Potential Way Forward to 6G  
The stakeholders are figuring out 6G design objectives as 5G is nearly at the point of technological realization in all of its features. To successfully operate internet of everything (IoE) services such as extended reality (XR) and networked autonomous systems, a wireless system must concurrently deliver high reliability, low latency, and high data rates, for heterogeneous devices, across uplink and downlink. Additionally, end-to-end co-design of computation, control, and communication functionalities will be necessary for emerging IoE services, which have been mostly neglected up until now. To support this new class of services, specific challenges must be overcome, such as characterizing the fundamental rate-reliability-latency tradeoffs that govern their performance, exploiting frequencies above sub-6 GHz, and converting wireless systems into a self-sustaining, intelligent network fabric that flexibly provisions and orchestrates communication-computing control-localization-sensing resources tailored to the required IoE scenario [34]. The various new use cases that we anticipate by 2030 and beyond will determine the new standards that 6G must meet. The data rate/throughput/capacity, latency, reliability, scale, and flexibility key performance indicators (KPIs) from 5G will continue to be crucial benchmarks for 6G performance. For 6G's anticipated use cases, several additional features will also be crucial, including (i) dynamic digital twins and virtual worlds; (ii) zero-energy devices; and (iii) wireless in data centres, etc [10]. In Figure 3, we categorise the require

ments for 6G into six categories three of which have KPIs identical to those of 5G and three of which are the new ones. 6G is also anticipated to address the difficulties unique to a space-air-ground integrated network (SAGIN). An integrated mobile communication network called SAGIN combines satellites, airborne platforms and terrestrial networks. The terrestrial networks are capable to provide standardized coverage of urban hotspots. In remote locations, on the sea, and in the air, satellite and airborne technology provide ubiquitous coverage. SAGIN is a deep integration of a system, technology, and application rather than merely connecting various communication networks. By integrating the RAN and CN, SAGIN creates a unified control plane and data plane, as well as a uniform terminal and air interface protocol. A robust control plane is developed by leveraging the deployment of the control network element. Moreover, to achieve seamless handover, intelligent mobility management technology is also deployed. Differentiated micro-service network elements with space-air characteristics are used to accomplish the space-air QoS provisioning, policy routing, resource allocation, and other network operation management activities. Despite the conceptual infancy of SAGIN, relevant stakeholders have provided several important insights into the improvement of terrestrial, aerial, and satellite systems. SAGINs are anticipated to cover a wider range of smart city scenarios, which present enormous and constantly changing diversified service requirements. This encourages the development of the IMT2020 usage case scenarios into further-eMBB (feMBB), ultra-mMTC (umMTC), extremely reliable and low latency communications (ERLLC), mobile broadband reliable low latency communications (MBRLLC), and massive-uRLLC (muRLLC).
