Study on 6G Scenarios and requirements
The present document reports on the scenarios and requirements for 6G Radio, which can be used as not only guidance to the technical work in 3GPP RAN WGs but also input for ITU-R when developing IMT-2030 technical performance requirements.
The objectives of the study item are:
• investigate a candidate set of items for minimum TPRs based on the Recommendation ITU-R M.2160, and, where applicable, the associated target values and key assumptions for the identified minimum TPRs.
◦ The outcome is expected to be shared by LS with ITU-R WP5D, as suitable, and used as a baseline for the subsequent study 6G in RAN
• Identify typical and practical deployment scenarios defined by attributes such as carrier frequency, inter-site distance, user density, maximum mobility speed, and other relevant factors.
• Develop 3GPP requirements for 6G Radio for improvement of existing services and for new services.
• Determine the applicability of legacy services to 6G Radio, and define radio requirements for these, as appropriate.
• Develop 3GPP requirements for 6G Radio for these practical deployment scenarios to ensure substantial gains in all relevant bands: overall performance, user experience, TCO reduction including at least:
◦ Ensure appropriate set of functionalities, minimize the adoption of multiple options for the same functionality, avoid excessive configurations, excessive UE capabilities and UE capabilities reporting
◦ Energy efficiency and energy saving: both for network and device
◦ Enhanced spectral efficiency
◦ Enhanced overall coverage, focus on cell-edge performance and UL coverage
◦ Wider channel bandwidth (at least 200MHz) support for 6G deployments at least above 2 GHz, around 7 GHz
◦ Re-use of existing 5G mid-band (~3.5GHz) site grid for 6G deployments in at least around 7 GHz and targeting comparable coverage to 5G mid-band
◦ Target scalable and forward compatible design for diverse device types
◦ Improved spectrum utilization and operations taking into account diverse spectrum allocations
◦ Aim at using common 6G Radio design, which meets mobile broadband service requirements as high priority, to also meet vertical needs
◦ Aim at a harmonized 6G Radio design for TN and NTN, including their integration
◦ System simplification, including reducing configuration complexity, enabling more efficient Cell/UE management, etc.
• Define a time plan and steer work as appropriate for the RAN WGs during the 6G WG SI to deliver high-level decisions at least on the following areas:
◦ Fundamental 6G radio design aspects: waveform, numerology, channel coding, etc…
◦ Overall high-level aspects of 5G to 6G migration
◦ RAN architecture and interfaces, including RAN-Core interface
◦ Coordination of 6G AI/ML framework
