1 Cindy Cook Canada WP8F Beyond IMT-2000 ITU-R SG8 Seminar

2 IMT-2000 Radio Access Standards Evolving Capabilities Evolving System Relationships Coverage Environments Variety of Access Networks Radio Access Phases Development Framework Technology Trends Spectrum Aspects R&D Activities Contents

3 Standards driven by market, technology & regulatory opportunities & segments Extensive use of references to detailed information held by external Recognized Organizations Many of these standards are already being enhanced A reminder ….. IMT-2000 Radio Access Standards

4 Standards Development Organizations Consortium & Partnerships CCSA Forums ITU Membership ITU Recommendations IMT-2000 Standards Development

5 Goal: anytime, anywhere, anyone – the deployment of IMT-2000 systems started in year 2000 Systems Beyond IMT-2000 capabilities, which extend and enhance IMT-2000, are expected to include: Higher data rates Improved roaming True inter-system mobility management Greater flexibility to support many different types of services simultaneously (example: symmetrical, asymmetrical & unidirectional services) Goal

6 IMT-2000 original minimum requirements for radio technology evaluation: 144 kbit/s for vehicular high speed 384 kbit/s for medium speed, and 2048 kbit/s for indoor and low speed Currently the standard supports up to 10 Mbit/s, and further enhancements are being developed, possibly up to 30 Mbit/s by 2005 Research targets for systems beyond IMT-2000 for deployment after 2010: 100 Mbit/s for high mobility 1Gbit/s for low mobility Evolving Capabilities

7 Along with the future development of IMT-2000 and systems beyond IMT-2000, relationships will continue to develop between different communications and radio access systems. Ex: Wireless personal area networks (WPANs) Local area networks (LANs and WLANs) Digital broadcast Fixed wireless access Systems will increasingly be designed as a combination of different access technologies Will provide a common and flexible service platform for different services and applications Key driver for this convergence is the increasing prevalence of IP-based applications Evolving Relationships

8 Fusion Recommendation ITU-R M.1645 "Systems beyond IMT 2000 should be realized by the functional fusion of existing, enhanced and newly developed elements of IMT-2000, nomadic wireless access systems and other wireless systems with high commonality and seamless interworking and interoperability"

9 Personal AreaWide Area Personal Area Immediate Area Wide Area Domains

10 IMT-2000 Coverage Environments

11 Variety of Access Networks for Systems Beyond IMT-2000 New radio interface(s) Research Goals: Mbit/s full mobility - 1 Gbit/s low mobility

12 Radio Access - Three Main Phases Enhancing IMT-2000 i.e. fast packet up to 10 Mbit/s, 30 Mbit/s by 2005 ? Relationship with other radio systems e.g. Digital broadcast, RLAN, etc. New radio interface(s) i.e. research target 100 – 1000 Mbit/s (full to low mobility)

13 Framework for Development (The Van) Interconnection IMT-2000 Mobility Low High Peak useful data rate (Mbit/s) Enhanced IMT-2000 Enhancement IMT-2000 Mobility Low High Area Wireless Access Enhanced IMT Enhancemen t Digital Broadcast SystemsNomadic / Local Area Access Systems New Nomadic / Local Systems beyond IMT-2000 will encompass the capabilities of previous systems New capabilities of systems beyond Dashed line indicates that the exact data rates associated with systems beyond IMT-2000 are not yet determined New Mobile Access

14 Significant technology trends need to be considered in defining the framework and objectives for systems beyond IMT-2000 R&D should consider these trends & provide guidance on their applicability or influence to systems beyond IMT-2000: System-related technologies, example: VoIP Seamless mobility Security & privacy Access network & radio interface, including Modulation and coding schemes Multiple access schemes Software defined radio & reconfigurable systems Adaptive radio interface New antenna concepts & technologies Technology Trends

15 Trends continued: Utilization of spectrum New techniques to increase spectrum utilization & efficiency, and to allow sharing of spectrum between users (ex. Adaptive antennas, MIMO, adaptive dynamic channel assignment) Mobile terminal, example technologies: Man-machine interfaces Software defined radio & multi-mode terminals RF MEMS Battery technology Applications Speech & video streaming APIs Data coding & compression techniques Technology Trends

16 Spectrum Need to plan use of spectrum already identified Recommendation ITU-R M , , and MHz Including new methods for reuse and sharing of spectrum; and new technologies for efficient use of spectrum WRC-07 agenda item to address future requirements Recommendation ITU-R M.1645 Resolution 802 (WRC 03) Resolution 228 (Rev.WRC-03)

17 2007 World Radiocommunication Conference Agenda item 1.4 to consider frequency-related matters for the future development of IMT 2000 and systems beyond IMT 2000, taking into account the results of ITU R studies in accordance with Resolution 228 (Rev.WRC 03) Resolution 802 (WRC 03)

18 resolves 1to further study technical and operational issues …; 2to report to WRC 07 on the spectrum requirements and potential frequency ranges …; 3to conduct regulatory and technical studies on the usage of frequencies below those identified for IMT-2000 …; 4to take into consideration the particular needs of developing countries including use of the satellite component of IMT 2000 …; 5to include sharing and compatibility studies with services already having allocations in potential spectrum …; 6that WRC 07 should consider frequency-related matters for the future development of IMT 2000 and systems beyond IMT 2000 …, Resolution 228 (Rev.WRC-03)

19 In analysing the spectrum implications of the future development of IMT-2000 and systems beyond IMT-2000, many issues must be addressed, including: Traffic projections & requirements Service & application requirements Spectrum efficiency Radio transmission characteristics Global roaming requirements & harmonized use of spectrum Technical solutions to facilitate global roaming Techniques of dynamic spectrum sharing Sharing and compatibility analysis Evolution of IMT-2000 systems Spectrum Implications

20 The Plan Other radio systems Evolution / Integration with other radio systems Indicates that the exact starting point is not yet fixed Possible spectrum identification at the WRC-07 Possible wide deployment around the year 2015 in some countries Systems Deployment Spectrum Implementation New elements to offer capabilities of systems beyond IMT-2000 FrameworkRequirementsStandardization Now WRC-07

21 Rec. ITU-R M.1645: Research, on a global basis, be undertaken to address the framework detailed in this Recommendation and into a potential new wireless access technique(s) for the terrestrial component Research on the specifications for the future development of IMT-2000 and systems beyond IMT-2000 consider how these systems may relate to other radio technologies and systems and how all systems will continue to evolve New technologies and technology trends be studied Research & Development

22 Research forums and other external organizations are encouraged to focus especially on: Radio interface(s) and their interoperability Access network related issues Spectrum related issues Traffic characteristics User estimations Many organizations currently involved in R&D of systems beyond IMT-2000 or B3G, including: WWRF – Wireless World Research Forum NGMC – Next Generation Mobile Communication mITF – mobile IT Forum CCSA – China Communications Standards Association External R&D

23 Flexibility is designed in from the outset Enhancements already being standardized and will evolve considerably over next years – open and market led Relationship with other radio systems will take place on a market led basis – regulatory considerations New radio interface(s) are expected to be required sometime between Spectrum aspects will be considered at WRC-07 Global cooperation of R&D fora encouraged Summary
