Core Content

This document outlines the current state of 5G spectrum development in Europe, emphasizing the importance of harmonization, licensing, and the role of international and regional initiatives in shaping the future of 5G. It highlights the need for Europe to align with global standards while ensuring the availability of spectrum for both commercial and experimental deployments.

Main Points

1. Introduction

• 5G Capabilities: 5G will enable massive connectivity, high throughput speeds, and reliable mobile communication, driving social, business, and industrial transformation.
• Spectrum Requirements: 5G will require both existing and new spectrum bands to meet its performance goals.
• ITU-R Role: The ITU-R is responsible for identifying spectrum bands for 5G under the IMT framework, with a focus on the 24.25–86 GHz range.
• 3GPP Progress: 3GPP has accelerated the development of 5G New Radio (NR) specifications, aiming for early deployments by 2019.

2. ITU-R Activities: Agenda Item 1.13 for WRC-19

• Frequency Bands for Study: The ITU-R has identified several frequency bands (24.25–86 GHz) for 5G spectrum study, though not all will be allocated.
• Approaches for Spectrum Needs:
  • Application-based approach: 2–3 GHz below 33.4 GHz, rising to 6–9 GHz above 66 GHz.
  • Technical Performance-based approach: 5.8–7.7 GHz below 43.5 GHz.
• Compatibility Studies: These are essential to ensure coexistence with incumbent services in the same frequency bands.
• Regional Considerations: The selection of bands will be influenced by local needs and industrial developments.

3. 3GPP 5G New Radio (NR) Development

• Release 15 Work Plan: Includes the development of Non-Standalone (NSA) and Standalone (SA) configurations.
• NSA 5G NR: Uses existing LTE infrastructure as an anchor, with early deployment expected in 2019.
• SA 5G NR: Requires a new 5G core network and full 5G capabilities.
• Band Specification: 3GPP is considering defining 3300–4200 MHz as a single band or two separate bands (n78 and n79) for 5G.
• Coexistence Mechanisms: Work is underway to enable efficient coexistence between LTE and 5G in the same bands.
• UL Pairing: Combining lower and higher bands (e.g., 3.5 GHz and 26 GHz) can improve coverage and efficiency.

4. Country and Regional Initiatives for 5G Spectrum Outside of Europe

• United States:
  • 600 MHz (low band) and 3.5 GHz (mid band) are key for early 5G.
  • 28 GHz and 39 GHz are high bands used for mmWave applications.
  • FCC has initiated spectrum auctions and is considering additional bands for flexible access.
• Korea:
  • 27.5–28.5 GHz and 3.4–3.7 GHz are allocated for 5G.
  • 26.5–27.5 GHz and 28.5–29.5 GHz are under consideration for 5G.
• China:
  • Trials in 3400–3600 MHz and 4800–5000 MHz.
  • Draft regulations for 3300–3600 MHz and 4800–5000 MHz bands.
• Japan:
  • 3600–4200 MHz, 4400–4900 MHz, and 28 GHz are being explored.
  • Public consultations are ongoing, with final rules expected by 2018.
• Australia:
  • Trials in 28 GHz and 39 GHz for the Commonwealth Games.
• Singapore:
  • Public consultation on spectrum bands below 1 GHz, 1–6 GHz, and above 6 GHz.
• Hong Kong:
  • Work plan includes low band, mid band (3.4–3.8 GHz), and mmWave (24.25–28.35 GHz) spectrum.

5. Development of 5G Spectrum in Europe

• European Commission Action Plan: Aims for 5G trials by 2017, early networks by 2018, and commercial services in major cities by 2020.
• Pioneer Bands: Identified as 700 MHz (below 1 GHz), 3.4–3.8 GHz (mid band), and 26 GHz (above 6 GHz).
• Harmonization Efforts:
  • 3.4–3.8 GHz and 26 GHz bands are being harmonized across Europe.
  • Spectrum awards are planned for 2017–2018 in several Member States.
• Licensing Considerations:
  • Harmonization of licensing conditions, duration, and types (licensed vs. license exempt) is critical for investment and 5G success.
  • Spectrum sharing and usage policies need to be developed to support vertical markets.

6. 700 MHz Regulation and Implementation

• Harmonized Band: 700 MHz is harmonized across Europe by ECC Decision (15)01 and Commission Implementing Decision (EU) 2016/687.
• Implementation Timeline:
  • By 30 June 2020, Member States must reassign the 700 MHz band to wireless broadband services.
  • Some countries have already completed or are in the process of implementing this band.
• SDL Option: Single Duplex Link (SDL) is being considered to provide additional downlink capacity in the 700 MHz band.

7. 3.4–3.8 GHz and 26 GHz Regulation and Implementation

• CEPT Mandate: The European Commission has tasked CEPT with developing harmonized technical conditions for 3.4–3.8 GHz and 26 GHz bands.
• Implementation Status:
  • The UK plans to auction 150 MHz in 2017 and additional 116 MHz in 2018/2019.
  • France will make 340 MHz available in 2018.
  • Germany and Spain are working on re-farming and auctioning these bands.
  • Italy, Ireland, and others have also initiated or completed spectrum allocation.

8. Recommendations for 5G Spectrum in Europe

• Early Implementation: DIGITALEUROPE recommends early implementation of the 700 MHz band and the SDL option to enhance downlink capacity.
• Harmonization: Emphasizes the importance of harmonizing technical conditions and licensing frameworks to support 5G deployment.
• Spectrum Sharing: Advocates for flexible spectrum sharing mechanisms to enable coexistence with existing services.
• International Alignment: Europe should align with global developments and contribute to international spectrum discussions.
• Long-term Planning: Consider extending mobile spectrum up to 4.2 GHz to meet growing demand for 5G services.
