# 6G Use Cases and Scenarios: A Comparison Analysis Between ITU and Other Initiatives
## 6 Next-Generation Mobile Network (NGMN)  
The NGMN comprises major global mobile network operators and industry stakeholders. It has released several documents in 2023 concerning 6G use cases and analysis [19; 20; 21]. NGMN invited its members to contribute their views on future 6G capabilities. They identified about 50 use cases that have been grouped into the following four classes:  
* Enhanced human communication. The advancement in human communication technology includes XR immersive holographic telepresence, multi-model communication for teleoperation, and intelligent interactions for sharing sensations, skills, and thoughts. \begin{table}

Table 4: List of use cases proposed by NGA, [17]. * Enhanced machine communication. The field of collaborative robotics involves autonomous devices equipped with sensors, including robot network fabric and interacting Cobots. * Enabling Services. The technology offers high-accuracy localization, 3D tracking, Digital Twins, virtual worlds, automatic detection protection, and trusted services in digital healthcare, and smart industries. * Network evolution. AIaaS includes trusted native AI, and it is a technology that focuses on energy efficiency and ubiquitous communication, and covers a wide range of applications. Table 5 summarizes the relationship between the use cases and the four classes that have been identified:  
These four classes are now detailed in terms of their representative use cases. The enhanced human communication class includes use cases on XR immersive holographic telepresence communication, multimodal communication for teleoperation, and intelligent interaction sharing of sensation, skills, and thought. The first use case underlines the role of human-centric extended immersive and 3D reality, such as Virtual Reality (VR), Augmented Reality (AR), and MR, together with holographic telepresence in work and for social interaction. Multimodal communication for teleoperation focuses on human multimodality information, including audio, video, taste, odor, haptic, and emotion, and on how it could be transferred over communication networks. The intelligent interaction sharing of sensations, skills thoughts is focused on Brain-Computer Interfaces (BCIs) enabling the real-time sharing of sensations and thoughts between humans and machines, transforming the human-machine interface. The second class, enhanced machine communication, is mainly focused on robot network fabric and interacting Cobot use cases. The first one is about the role of 6G in traffic management to ensure safe, collision-free, and efficient traffic in a heterogeneous environment. Examples are autonomous mobile robots, drones, and Automated Guided Vehicles (AGVs). The second one is about Cobots. They are expected to enhance human-robot interaction to interpret human actions, respond in a trustworthy way, and assist humans efficiently and safely. The third class, Enabling Services, includes the following representative use cases: 3D hyper-accurate positioning, localization, and tracking, interactive mapping, digital
