5G Access

  1. 1. 5G Access Simon Pike Vodafone Spectrum Policy Forum Cluster 2 meeting on mm-waves - 16 December 15 (with clarifications added after the meeting)
  2. 2. • Availability of spectrum – Agenda item for WRC-19, addressing bands between 24GHz and 86GHz – ITU Co-existence studies will be carried out in a new group, ITU-R TG 5/1 – Parameters of 5G (IMT-2020) for these studies will be defined by ITU-R WP5D – Propagation models will be developed in ITU-R Study Group 3 – These need to be available for the co-existence studies by March 2017 • Definition of user requirements – NGMN Project P1 and 3GPP TSG SA • Development of 5G specifications – 3GPP TSG RAN – 5G workshop held and study item starts in 2016 • Definition and evaluation of 5G / IMT-2020 – ITU-R WP5D • National initiatives – especially Korea, Japan and USA Drivers for development of 5G at mm-waves Spectrum Policy Forum Cluster 2; mmWaves; - 5G access – C1 (Public)
  3. 3. • WRC-15 did not result in much extra spectrum for mobile in Europe – Only 1427 – 1452MHz and 1492 – 1518MHz are not already on the EU spectrum roadmap – This will be for supplementary downlink, so not suitable for initial 5G deployment – UHF band (470 – 694MHz) will not be considered until WRC-23 • WRC-19 agreed an agenda item for WRC-19 on spectrum for IMT • The studies and decisions by WRC-19 are limited to the following bands, all above 24GHz Already allocated to the Mobile Service in the Table of Allocations: 24.25-27.5 GHz 37-40.5 GHz, 42.5-43.5 GHz, 45.5-47 GHz, 47.2-50.2 GHz and 50.4-52.6 GHz 66-76 GHz and 81-86 GHz Would require a new allocation to the Mobile Service in the Table of Allocations: 31.8-33.4 GHz, 40.5-42.5 GHz and 47-47.2 GHz • 27.5 – 29.5GHz is not included, despite being strongly supported by USA, Korea and Japan Spectrum Policy Forum Cluster 2; mmWaves; - 5G access – C1 (Public) Outcome of WRC-15 and preparations for WRC- 19
  4. 4. • Every major mobile vendor has a research programme on 5G • Many countries have national 5G research institutes or programmes • There has been a historical tendency to focus on the highest peak bit rate Spectrum Policy Forum Cluster 2; mmWaves; - 5G access – C1 (Public) 5G Technology development and trials – This has driven the studies towards wide channel bandwidths and high frequencies • Some aspects of mm-wave propagation are not yet well understood • Several vendors already have trial systems – But they are not yet fully representative – A limited range of environments – Terminals, and even antennas, are not representative – They are not mature enough to test applications • Likely bandwidth of RF subsystem ~ 25%

  6. 6. • LTE is already close to the Shannon limit for a single radio link – The benefit of 5G in existing bands will come from new techniques in the access networks – e.g. greater flexibility in the radio interface • We expect that 5G deployment will be driven by new use cases (verticals) – e.g. automotive, e-health, utilities, industrial automation, logistics, M2M – Some aspects of these cannot be delivered efficiently to the mass market with 4G – These use cases will generate new revenue streams • Most of these use cases require wide area coverage – We therefore envisage that the initial deployment of 5G will be in lower frequency bands • In other countries (e.g. Korea, Japan), the driver for 5G appears to be ultra-fast broadband • The feasible use cases for > 24GHz for mobile are not yet well understood – In particular, the ability to serve indoor users from outdoor ‘access points’ • Bands > 24GHz will not be identified until WRC-19 – Licence awards will not happen until 2021 – 22 • Where will the spectrum for initial deployment of 5G come from?

  7. 7. • By 2020, there will probably already be two ecosystems for mm-waves – WiGIG at 60GHz for consumer electronics – Automotive radar at 79GHz for vehicles • The 66-71GHz band sits between these two bands – It is probably close enough to share common RF components with either ecosystem – Vodafone has therefore expressed interest in this band in Ofcom consultations • Frequency bands below 66GHz undoubtedly have more favourable propagation – For WRC-19, going down from 52.6GHzto 24.25GHz – However, it is unclear if the difference is great enough to enable additional use cases • There needs to be a common global implementation of 5G in devices – This is likely to need a single RF subsystem for the new band(s), at least during the launch period – The bandwidth of a subsystem is likely to be around 25% Spectrum Policy Forum Cluster 2; mmWaves; - 5G access – C1 (Public) Preferred frequency bands “above 24GHz” for 5G (presented orally at the meeting)
