爱立信+6G频谱——实现2030年以后的未来移动生活-27页_1mb

报告摘要

6G will enable immersive digital experiences (XR, holographic comms), internet of senses, massive digital twins, and sustainable living.
These technologies will transform lifestyles, reduce emissions, and reshape sectors like healthcare, education, and Industry 4.0.

Wide-area coverage: Holographic comms (~1Gbit/s per user), internet of senses, massive digital twins require more spectrum. Ericsson estimates ~3 GHz needed for wide-area use cases.
Local/niche: Professional holographic comms, remote surgery may require 10-100 Gbit/s data rates, driving need for localized spectrum (~10–15 GHz).
Sub-THz: W band (e.g., 92–100 GHz) for extreme use cases (e.g., ultra-high speed gaming, direct device-to-device comms). D band (~116–122 GHz) for backhaul.

Mid-band (3.3–7.125 GHz)
- Insufficient by 2030: Shortfall estimated at 1.5–2.2 GHz due to growing data demands.
- Critical: Low-band (e.g., sub-600 MHz) essential for rural and deep indoor coverage.
7–15 GHz Centimetric
- Urged for IMT identification: To support mobility, wide-area coverage, and capacity. Initial bands suggested: 7.125–8.5 GHz, 10.7–13.25 GHz, 14–15.35 GHz.
- Action: Authorize for wide-area use and harmonization.
Sub-THz (92–300 GHz)
- Limited coverage but high capacity: Use for niche high-data-rate scenarios (e.g., ultra HD holographic comms).
- Regime: Licensed access (smaller enclosed buildings or confined areas).

Spectrum Availability: Needs to be available by ~2030 to support 6G deployment.
Standardization: Ericsson expects first 6G specs (3GPP) in 2028.
Pathway: Licensing through:
- International Telecommunication Union (ITU) harmonization via World Radiocommunication Conferences (WRC-23/27 targets).
- Regional decisions complement with national/individual actions.
Key Recommendations:
- Harmonize 7–15 GHz bands for global deployment.
- Accelerate equipment development suited for sub-THz.
- Conduct sharing/coexistence studies with incumbent services.
