Review of WRC2000on IMT-2000(III) • Items to be studied(Annex 1 of COM5/24) • sharing implications and possibilities; • harmonized frequency arrangements, taking into account the need to facilitate the evolution of current mobile systems to IMT-2000; • means to facilitate global roaming across different regional band usage; • spectrum demand predictions related to traffic density and timing; • planning tools for adaptation of mobile radiocommunication technologies for the needs of developing countries; • maintaining a database of national studies and decisions on selection of spectrum for IMT-2000; • study of the provision of a fixed wireless access interface using IMT-2000 technologies.
Review of WRC2000on IMT-2000(IV) • RES. COM5/13; IMT HAPS • to complete, as a matter of urgency, additional regulatory, operational and technical studies on sharing criteria for HAPS with other systems in the bands 1 885-1 980 MHz, 2 010-2 025 MHz and 2 110-2 170 MHz in Regions 1 and 3 and 1 885-1 980 MHz and 2 110-2 160 in Region 2, and in adjacent bands, so as to allow revision of the values in resolves 1; • to develop appropriate regulatory and technical provisions to allow the coordination mentioned in resolves 4; • to report on the results of these studies in time for consideration by WRC-03.
IMT & Systems BeyondITU-R Working Party 8F Stephen Blust (WP8F Chairman) …... • " WP8F, replacing TG 8/1, is the global focal point for the continuing vision of next generation wireless services and systems, acting as a forum for user requirements and as a catalyst for translating those requirements into technical reality ". • " WP8F has the challenging task of supporting the near term needs of the IMT-2000 marketplace while exploring where we might go in the wireless world of the future".

Spectrum ; Issues • Develop a global IMT-2000 Spectrum Plan Recomendation • consider all of the IMT spectrum as a package • take a medium and long term view • accommodate 2G evolution • first step - look at all options • later steps - narrow down option(s) • Preparations for WRC-2003/6 • Sharing studies • Preliminary work on future spectrum requirements / methodology etc • HAPS

Spectrum Issue2nd WP8F • Guidelines in the development of frequency arrangements for IMT-2000 in the bands identified at WRC-2000, and key technological/market based questions to be addressed in the development of optimum global frequency arrangements, • Example frequency planning options • WRC2003 agenda item 1.34 (protection requirements for IMT-2000 systems sharing with the broadcasting-satellite service at 2.6 GHz,) • WRC2003 agenda item 1.33 (HAPS) • Framework for CPM text relating to future requirements for IMT-2000 and systems beyond (WRC2003 agenda item 1.22) • Methodologies for assessing sharing between IMT-2000 and other services, including sharing between IMT-2000 and ARNS in the frequency band 2 700 – 2 900 MHz
Spectrum Issue(cont.)Parameters to be considered2nd WP8F • Traffic asymmetry • Duplex direction • Constraints on duplex separation and transmit/receive band separation due to technology limitations • Requirements for guard-bands (e.g., between FDD and TDD modes) • Evolution within bands currently used by pre-IMT-2000 systems • Global roaming
Global Circulation2nd WP8F • Global circulation and conformity assessment • Working document towards a PDNR on the global circulation of IMT-2000 terminals • Conformity assessment • Unwanted emissions • Measurement uncertainty • 3GPP vis-à-vis 3GPP2
Developing2nd WP8F • The following critical points are identified which need further work : • Development Related : • Use of IMT-2000 RTT as Fixed Wireless Access & IMT-2000 as Integrated network. • Standardisation of RAN-CN and Intra-RAN interfaces. • Deployment Related : • Mechanism on information collection from developing countries on the plans and the related issues of deployment of IMT-2000 that need to be addressed in the Handbook on the Deployment of IMT-2000 .
Adding value - the future • 1998 (1990) - developed additionalspectrum reqt for IMT-2000 • 2000 (1992) - WRC identifies additional spectrum for IMT-2000 in Radio Regs through a footnote • Continue to promote the IMT-2000 concept and systems beyond while people are still busy trying to get initial IMT (2G) working and successful • Define realistic but challengingvision; concept, principles, framework and requirements
Adding value - the future • Maintain the link between spectrum / licensing / radio interface specifications • Global from the outset • Build furtheron the excellent working arrangements with the Global Partnerships and external organisations - referencing within Framework Rec’s • Continue to foster Global ‘buy in’ • Develop a global spectrum plan
