  1. Third Generation Developments A presentation for the Mobile Services Committee RA2/PTNRadiocommunications Agency RADIOCOMMUNICATIONS AGENCY

  2. WARC-92 outcome • At WARC-92 the following bands were identified on a wordwide basis for IMT-2000 applications: 1900 2000 2100 2200 IMT - 2000 IMT - 2000 MSS MSS 1885 1980 2010 2025 2110 2170 2200

  3. UK spectrum allocations • The IMT-2000 spectrum identified at WARC-92 has been allocated in the UK as follows: 1900 2000 2100 2200 FDD Licensed FDD Licensed MSS MSS DECT TDD Licensed TDD Exempt 1880 1900 1920 1980 2010 2025 2110 2170 2200

  4. UK licences • Following a spectrum auction in the spring of 2000 five UK UMTS licences were awarded as follows: • Hutchinson 3G- 2 x 15 MHz FDD + 5 MHz TDD • BT Cellnet - 2 x 10 MHz FDD + 5 MHz TDD • Vodafone - 2 x 15 MHz FDD • One2One - 2 x 10 MHz FDD + 5 MHz TDD • Orange - 2 x 10 MHz FDD + 5 MHz TDD

  5. IMT-2000 Terrestrial Radio Interfaces • IMT-2000 CDMA Direct Spread (UTRA FDD) • IMT-2000 CDMA Multi-Carrier (cdma 2000) • IMT-2000 CDMA TDD (UTRA TDD) • IMT-2000 TDMA Single Carrier (UWC-136) • IMT-2000 FDMA/TDMA (DECT)

  6. WRC-2000 outcome • Three additional frequency bands were identified for IMT-2000 applications as follows: • 806 - 960 MHz RR Footnote S5.317A • 1710 - 1885 MHz RR Footnote S5.384A • 2500 - 2590 MHz RR Footnote S5.384A • WRC-2000 also maintained the status of the original WARC-92 IMT-2000 bands

  7. Development post WRC-2000 • Three key Groups • Within Europe ERC PT1 has been charged with developing the CEPT positions on spectrum packaging and related issues - e.g. global circulation • Within the ITU-R Working Party 8F has responsibility within SG8 for IMT-2000 and systems beyond • Standardisation • 3GPP • 3GPP2

  8. ITU-R WP8F structure • WP8F is organised into six working groups: • WG Spectrum • WG Radio Technology (M.1457) • WG Vision • WG Circulation (now closed) • WG Satellite Co-ordination • WG Developing IMT

  9. ITU-R WP8F post WRC-2000 • WP8F continue to develop work on the preferred frequency options for both the WARC-92 and WRC-2000 bands • The general approach has been to maintain flexibility and facilitate migration from 2G to 3G services by maintaining duplex directions and spacings as far as possible

  10. Preferred frequency options1710 - 2200 MHz

  11. Preferred frequency options806 - 960 MHz Band

  12. Preferred frequency options2500 - 2690 MHz band • The following three basic arrangements or combinations of them are expected to meet the demand for additional traffic; the aggregate asymmetry is as yet unknown but is assumed to be biased towards the downlink: • a) FDD Up- and Downlink operation • b) FDD Downlink operation • c) TDD operation

  13. Generic principle for2500 - 2690 MHz band 2500 MHz 2690 MHz A B C D It should be noted that the edges of sub-bands A and D may be influenced by the use of the bands 2500-2520 MHz and 2670-2690 MHz by the satellite component of IMT-2000 (resolves 2 of Resolution 225).

  14. Systems beyond IMT - 2000 Mobility BS digital New Elements High Broadcasting of Systems Beyond Mobile Enhanced Terrestrial digital IMT - 2000 Access IMT - 2000 broadcasting Medium Enhancement Nomadic / Local area wireless access Low 1 10 100 Communication speed ( Mbit/s ) denotes interconnection between systems via networks or the like, which allows flexible use in any environments without making users aware of constituent systems. Vision of systems beyondIMT-2000

  15. EU Mandate 4 to CEPT • On 9 March 2000 the European Commission issued a mandate to CEPT to: • “… harmonise frequency usage in order to facilitate a co-ordinated implementation in the community of third generation mobile and wireless communications systems operating in additional frequency bands as identified by the WRC-2000 for IMT-2000 systems.” • Further mandates are expected at a later stage to establish the spectrum channelling arrangements for additional spectrum

  16. Mandate deliverables • Report from CEPT by November 2001 with initial proposals for: • amount of additional spectrum needed; • frequency bands to accommodate additional spectrum; • ‘reference date’ to make additional spectrum available • analysis of global roaming implications • CEPT Report by November 2002 • validation of initial proposals, confirmation of ‘reference date’ • CEPT Decision by March 2003 • designation of additional spectrum to be used for IMT-2000 as from ‘reference date’

  17. PT1 response to EU Mandate • The main conclusion from the executive summary to the initial report from CEPT are: • CEPT confirms the preferred band for additional terrestrial spectrum is the 2500 - 2690 MHz band • the 2500 - 2690 MHz band should be made available from 2008 within CEPT (though due to current uncertainty in real availability of services, flexibility should be maintained on the definition of this date.) • channelling arrangements for the 2500 - 2690 MHz band should not be fixed until the 2004/2005 timeframe.

  18. 3rd Generation Partnership Project • Release 99 • W-CDMA and TD-CDMA radio interfaces • circuit-switched data up to 64 kbit/s • packet-switched data up to 384 kbit/s • core network compatible with GSM Phase 2+ R99 • Release 4 • enhancements beyond Release 99 • 1.28 Mcps TDD • base station classification • FDD repeaters

  19. 3rd Generation Partnership Project • Current work • Corrections and clarifications for Release 99 and Release 4 • High Speed Downlink Packet Access • IP Multimedia Subsystem • First IMS elements to appear in Release 5 • Further IMS elements in Release 6 • Further studies ongoing beyond Release 6 (e.g. IPv4/v6)
