Summary of 5G Spectrum Options for Europe

Core Content

This document outlines the current landscape and future considerations for 5G spectrum options in Europe, emphasizing the need for harmonization, early implementation, and alignment with international developments. It discusses both the global and regional initiatives that are shaping the availability and use of 5G frequency bands, as well as the technical and regulatory challenges involved in deploying 5G networks.

Main Points

1. 5G Capabilities and Spectrum Requirements

• 5G is expected to enable high throughput, massive connectivity, and reliable mobile communications.
• It will require both existing and new spectrum resources, particularly in higher frequency bands to meet its performance goals.
• The ITU-R is studying frequency bands between 24.25 GHz and 86 GHz for 5G, though not all bands will be allocated.
• Spectrum needs are estimated to range from 2-3 GHz in lower bands to 6-9 GHz in higher bands.

2. ITU-R Activities and Studies

• ITU-R Resolution 238 (WRC-15) has initiated studies for 5G spectrum in the 24.25–86 GHz range.
• These studies include compatibility assessments with existing services and the identification of bands suitable for 5G.
• The results of these studies will influence the final allocation decisions during WRC-19.

3. 3GPP Work and 5G NR Specifications

• 3GPP has accelerated the development of 5G New Radio (NR) specifications, aiming for early 2019 deployments.
• Two main variants are being developed: Non-Standalone (NSA) using LTE as a core, and Standalone (SA) using a new 5G core network.
• 3GPP is also working on defining new 5G-NR bands, with the first release expected by June 2018.
• Key bands under discussion include:
  • C-band: 3300–4200 MHz (with sub-bands)
  • 26 GHz: 24.25–27.5 GHz
  • 28 GHz: 26.5–29.5 GHz
  • 39 GHz: 37–40 GHz
  • Millimeter Wave bands: 64–71 GHz (license exempt)

4. Country and Regional Initiatives

• Several countries outside Europe have taken steps to identify and allocate spectrum for 5G:
  • USA: FCC has allocated bands such as 600 MHz, 3.5 GHz, 28 GHz, and 39 GHz for 5G, with a focus on mmWave and flexible access.
  • Korea: Allocating 4 GHz of mmWave spectrum in three phases, starting with 27.5–28.5 GHz and 3.4–3.7 GHz.
  • China: Conducting trials in 3400–3600 MHz and 4800–5000 MHz, and consulting on 24.75–27.5 GHz and 37–42 GHz for IMT-2020.
  • Japan: Investigating bands such as 3600–4200 MHz, 4400–4900 MHz, and 28 GHz for 5G.
  • Australia: Targeting 3.4–3.7 GHz and mmWave for 5G.
  • Singapore: Conducting public consultations on bands below and above 6 GHz, including 26 GHz and 28 GHz.
  • Hong Kong: Planning for 3.4–3.8 GHz and 24.25–28.35 GHz for 5G.

5. 5G Spectrum Development in Europe

• The European Commission has outlined a timeline for 5G deployment, including trials by 2017, early networks by 2018, and commercial services by 2020.
• Pioneer bands identified for 5G in Europe include:
  • Below 1 GHz: 700 MHz
  • 1–6 GHz: 3.4–3.8 GHz
  • Above 6 GHz: 26 GHz
• Regulatory bodies across Europe are working on harmonizing spectrum use and planning auctions for these bands in the 2017–2018 timeframe.
• The 700 MHz band is already harmonized in Europe and provides excellent coverage for both mobile broadband and IoT services.
• 3.4–3.8 GHz is being considered for 5G, with a focus on reducing fragmentation and enabling contiguous spectrum blocks for operators.
• 26 GHz is also being studied for 5G, with various countries planning trials and auctions in the 2017–2019 timeframe.

6. Spectrum Sharing and Licensing Considerations

• Harmonization of licensing conditions, duration, and the balance between licensed and license-exempt bands is crucial for encouraging investment in 5G.
• The RSPG has recommended specific bands for 5G in Europe, and is working on a second opinion to address spectrum sharing, usage, and other regulatory challenges.
• Single License (SDL) and paired frequency arrangements (FDD) are being explored for 700 MHz and 3.4–3.8 GHz to improve efficiency and coverage.

Key Information

• 700 MHz: Harmonized in Europe, with plans to reassign to wireless broadband by 2020.
• 3.4–3.8 GHz: Key mid-band for 5G, with harmonization and auction plans in several countries.
• 26 GHz (24.25–27.5 GHz): Being studied for 5G, with various countries planning trials and spectrum release by 2019.
• 3GPP and ITU-R: Both are actively working on 5G standards and spectrum definitions, with the first 5G NR specification expected by 2018.
• International alignment: The US, Korea, China, and Japan are leading in 5G spectrum allocation and trials, influencing Europe’s strategy.
• DIGITALEUROPE recommendations: Support for early implementation of 700 MHz, 3.4–3.8 GHz, and 26 GHz, with a focus on harmonization and reducing fragmentation.

Conclusion

The development of 5G spectrum in Europe is a multi-faceted process involving international standards, national regulatory actions, and industry collaboration. Early implementation of key bands such as 700 MHz, 3.4–3.8 GHz, and 26 GHz is essential to ensure Europe remains competitive and capable of meeting the demands of future 5G applications. Harmonization and flexible licensing are critical to enabling efficient and widespread deployment of 5G across the continent.
