# Quality of Experience in 6G Networks: Outlook and Challenges
## 4 Sixth Generation Services and Features  
There are indicators that 6G will allow for service delivery in a manner that capitalizes on excessive bandwidth availability, responsive communication, and the capability to promptly process and respond to a rich and dynamic context [6, 7, 8]. Relative to current features or even those of 5G networks, the extent to which these features will be offered is far-reaching to great degrees. For example, augmented and virtual reality (AR and VR) services are already taking hold today in different gaming boxes. As these services evolve, a richer and more responsive context will be delivered to the users, even with multiple simultaneous inputs being made.  
Digital twinning is a core feature of Industry 4.0 that must be considered, whereby a digitized replica of an actual realistic environment, e.g., factory or office space, is fully simulated to the user. The realization of this twinning so far has been impeded by two factors: computation and communication. However, digital twinning now appears more viable, with 6G networks availing a combined breakthrough in both.  
Another expected service in 6G networks is tactile Internet, which will further the user experience with aspects such as weight, temperature, or speed. Such aspects are crucial in various contexts where the need for prompt remote control is present. These contexts include remote surgery, manufacturing, or navigation. This is an example of service enrichments that motivate the use of high-precision networking.  
Extended reality (XR) and mixed reality (MR) are other forms that are indicative of service expectations. Through these, user experience becomes dependent on personal interaction and interaction with the user's surroundings. This is particularly the case in MR, where physical objects can both obscure and impact virtualized objects. Cost-effective high-resolution and responsive holographs may be available by 2030, adding a further dimension to user-context enrichment.  
Support for V2X communication in 5G will play a significant role in the evolution of autonomic vehicles [63]. Moreover, 6G networks will further enable the rise of autonomy in other applications, especially in manufacturing and remote applications. These applications will depend heavily on computing and communication advances, especially in terms of distributed intelligence.  
In addition, 6G networks may finally deliver on the notion of AI or machine learning (ML) ML as a service (AI/MLaaS). This entails the availability of platforms whereby intelligence tasks can be requested or exchanged. In turn, AI/ML platforms can utilize these various \"experiences\" and access valuable insights relevant or applicable across different verticals.  
The mobile user experience in 6G networks will thus exhibit significant enhancements. The viability of (hyper-) individualized mobile experiences is more significant. As discussed above, network operators will be able to direct network operation through intent-based or mandate-based networking [60]. The premise of the campus deployments in 5G was tailoring network operations depending on the needs of enterprise consumers. In 6G, it can be envisioned that personalization and tailoring can occur at the individual consumer level. This individualization will be made possible through a ubiquitous intelligence that can promptly and effectively understand user needs. More importantly, it will better understand the user's impression of network delivery.
