WARC-92 outcome At WARC-92 the following bands were identified on a wordwide basis for IMT-2000 applications: IMT MSS

UK spectrum allocations DECT MSS FDD Licensed TDD Exempt 1920 TDD Licensed 2010 The IMT-2000 spectrum identified at WARC- 92 has been allocated in the UK as follows:

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

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)

WRC-2000 outcome Three additional frequency bands were identified for IMT-2000 applications as follows: – MHzRR Footnote S5.317A – MHzRR Footnote S5.384A – MHzRR Footnote S5.384A WRC-2000 also maintained the status of the original WARC-92 IMT-2000 bands

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

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

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

Preferred frequency options MHz

Preferred frequency options MHz Band

Preferred frequency options 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

Generic principle for MHz band It should be noted that the edges of sub-bands A and D may be influenced by the use of the bands MHz and MHz by the satellite component of IMT-2000 (resolves 2 of Resolution 225) MHz2690 MHz ABCD

Vision of systems beyond IMT-2000

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

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’

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 MHz band –the 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 MHz band should not be fixed until the 2004/2005 timeframe.
