3GPP Completes 6G Service Requirements Study: AI, Integrated Sensing and Communication, and Immersive Communications Emerge as Core Applications
The 3GPP SA1 working group has completed its Release 20 study on “6G Use Cases and Service Requirements”, with the findings compiled in Technical Report TR 22.870. The study lays the groundwork for subsequent standardization efforts covering 6G system architecture, radio access networks, and core networks. Conducted over approximately two years, the study comprehensively examined potential services, use cases, functional requirements, and performance requirements for future 6G networks. The findings indicate that 6G will go beyond simply increasing mobile network speeds and instead evolve toward AI-native networking, integrated sensing and communication, immersive communications, ubiquitous connectivity, and convergence between communications and computing.
According to the 3GPP study, TR 22.870 covers approximately 161 use cases, 473 potential requirements, 243 consolidated potential requirements, and 22 KPI tables. These cover a broad range of areas, including system and operational aspects, AI, Integrated Sensing and Communication (ISAC), Ubiquitous Connectivity, Immersive Communication, massive communications, and industrial and vertical applications.
AI and Communications Convergence: 6G Moves Toward AI-Native Networks
AI is regarded as one of the key capabilities of 6G. The 3GPP study includes a range of AI-related use cases, including collaborative communications among AI agents, AI/ML model training and inference, and user-experience optimization for generative AI (GenAI) applications.
Under this vision, 6G networks will not merely serve as data transmission channels for AI applications, but may also provide resources for AI model training, inference, and computing, creating a more closely integrated architecture connecting networks, devices, and AI services. For example, 6G could provide computing resources for AI text-to-video generation, AI model inference, and XR content rendering, further enabling communication-computing coordination.
3GPP further points out that the role of future 6G networks is expected to evolve from traditional “data transmission channels” into data producers, data consumers, and computing service providers. In addition to transmitting data, networks will process new types of information, including AI model data, sensing data, and Digital Twin data, while exploring new architectures such as In-Network Computing.
ISAC Becomes a Key 6G Capability, Further Integrating Communications and Sensing
Integrated Sensing and Communication (ISAC) is another major development direction for 6G. By integrating wireless communications and sensing capabilities, future networks could use wireless signals to detect and track people, vehicles, drones, robots, and other objects, supporting applications such as smart transportation, industrial automation, and security monitoring.
Under this approach, base stations and network equipment would no longer serve solely as connectivity infrastructure, but could also function as environmental sensing infrastructure, providing information about location, movement, and surrounding conditions. The 3GPP study also covers the collection and processing of sensing data, as well as support for mission-critical sensing services.
Immersive Communications to Drive XR, Digital Twins, and New Human-Machine Interactions
In the area of immersive communications, 3GPP identifies Augmented Reality (AR), Virtual Reality (VR), Mixed Reality (MR), holographic communications, telepresence, and Digital Twins as important 6G application areas.
While 5G has primarily focused on enhanced mobile broadband, 6G is expected to pursue greater levels of real-time responsiveness, immersion, and multisensory interaction, enabling users to engage in more natural remote interactions through visual, auditory, and potentially other sensory modalities. These capabilities could drive new services across entertainment, healthcare, education, manufacturing, and enterprise collaboration.
Ubiquitous Connectivity and Satellite Communications Integrated into the 6G Architecture 3GPP's 6G study also identifies Ubiquitous Connectivity as a major development direction, emphasizing the need for future networks to provide broader coverage and support diverse types of devices and network environments.
Non-Terrestrial Networks (NTN) are also included in the study, covering coordination between satellite systems and terrestrial mobile networks. Future 6G networks are expected to further integrate terrestrial and non-terrestrial networks to provide services such as positioning, timing, and wide-area connectivity, while extending coverage to areas that are difficult for conventional terrestrial networks to reach.
6G Applications Extend Further into Industrial and Vertical Sectors
In addition to AI, ISAC, and immersive communications, 3GPP has included smart factories, collaborative robots, Industrial IoT, Digital Twins, smart grids, drones, and autonomous systems in its 6G study.
For example, 6G could support collaboration among multiple mobile robots by integrating sensing, communications, and computing capabilities. Robots could obtain real-time environmental information, make decisions, and coordinate with one another. Critical infrastructure such as smart grids could also leverage 6G to provide real-time data transmission and monitoring capabilities.
From “Higher Speeds” to an “Intelligent Network Platform”
Overall, the 3GPP SA1 6G study demonstrates that the technological vision for 6G extends well beyond that of simply being the next generation of mobile communications. Compared with 5G's emphasis on mobile broadband, low latency, and massive IoT, 6G will further integrate AI, communications, sensing, computing, and data capabilities to create a new type of intelligent network platform capable of supporting intelligent decision-making and service delivery.
3GPP indicates that future 6G standardization will build on the findings of this study and advance the development of subsequent system architectures and technical specifications. At the same time, 6G will maintain interoperability and evolutionary compatibility with existing 5G systems while addressing requirements related to security, resilience, sustainability, and energy efficiency. The study results are expected to serve as an important foundation for the subsequent development of 6G specifications in 3GPP Release 21.
