There will be new advanced services in 6G era, which require a tremendous amount of real-time data processing, a hyper-fast data rate, and extremely low latency, as discussed in Section 2. These new services can be characterized as providing ultimate experience through hyper-connectivity. Relying only on improvement of the communication link performance does not suffice to realize new 6G services. This is because the progress of increase in mobile computing power is not keeping pace with the growth rate of the computing power requirements as shown in Figure 6. Also, the improvement of mobile devices’ battery life is not fast enough given the extensive demand for multimedia services and their rapid evolution.
The limitation on computing power and battery life of mobile devices highlights the need for taking a holistic view on the overall architecture of 6G system including network entities as well as mobile devices. In addition, the openness of mobile communications as a new megatrend toward 6G (see Section 1) gives rise to the need for defining new requirements to maintain security and keep the trust of subscribers.
To provide the ultimate experience of delay-sensitive real-time applications such as interactive tactile internet, latency-related performance needs to significantly improve. Performance targets include air latency less than 100 μs, end-to-end (E2E) latency less than 1 ms, and extremely low delay jitter in the order of microseconds. With these requirements satisfied, the user experienced latency can be less than 10 ms, which is the motion-to-photon latency requirement for XR services . The user experienced latency requirement applies to the aggregate of all latency components in wireless links, wireline links, and the computation on both client and server sides.
