  1. 1. COGNITIVE AND SOFTWARE DEFINED RADIO at WRC -07 and -11 by Chris van Diepenbeek Radiocommunications Agency of The Netherlands 1 11 May 2009 IBBTWRC-07 Workshop
  2. 2. ITU and WRC  What is ITU  Why a WRC  Data and mechanics  Decision Process  Non-radio Problems 2 11 May 2009 IBBTWRC-07 Workshop
  3. 3. The International Telecommunication Union  UN Organisation in Geneva (1947)  191 Members (Administrations)  700 Sector Members (Operators, Int. Organisations, Industry)  Nearly 145 years old (17-05-1865)  Worldwide harmonisation of, co-operation in, and development of telecommunications 3 11 May 2009 IBBTWRC-07 Workshop
  4. 4. Radio Regulations (RR’s)  ITU activities are based on an international treaty ( Constitution and Convention)  Binding Complementary parts:   Radio Regulations   International Telecommunications Regulations  Radio Regulations have treaty status 4 11 May 2009 IBBTWRC-07 Workshop
  5. 5. Objectives of RR’s   Promote international co-operation for improvement of telecommunications of all kind:   Allocation of spectrum   Orbital Positions   Allotments of frequencies   Registration of Assignments both for Terrestrial and Space Services 5 11 May 2009 IBBTWRC-07 Workshop
  6. 6. RR’s: to avoid problems  Radio Regulations concern relations between countries  If no risk for interference, no need, but  Radio waves don’t stop at borders  One has to co-ordinate orbital positions, and  Trade is international, and  There is a need for common language 6 11 May 2009 IBBTWRC-07 Workshop
  7. 7. RR’s: to enjoy benefits  Worldwide use, e.g. Maritime  Harmonisation, e.g. IMT  Common sharing criteria, e.g. UWB  Common protection criteria, e.g. Passive Services  Common procedures, e.g. Satellites  Common approach to new technology, e.g. BWA or CR 7 11 May 2009 IBBTWRC-07 Workshop
  8. 8. Some Data  2500 delegates  150 countries, 50 observers  6 Languages  About 400 documents  WRC-03: 30.000.000 copies  Now mostly electronic doc’s  Plenary, Committee, Working Group, Drafting Group  4 weeks, in general in Geneva 8 11 May 2009 IBBTWRC-07 Workshop
  9. 9. 7 Committees  1: Steering  2: Credentials  3: Budget  4, 5 and 6: On Substance  Each of these creates Working Groups  7: Editorial 9 11 May 2009 IBBTWRC-07 Workshop
  10. 10. The formal process Negotiation process The formal Plenary Plenary process is strictly hierarchical Committee Committee WG WG DG DG 10 11 May 2009 IBBTWRC-07 Workshop
  11. 11. The informal process  Stamina: lengthy negotiation process, late night sessions  An informal process may exist in making a deal:  including an issue not for ITU  on issues covered by the agenda  Package deal: We give you a bit more on this item, and you get a bit less of that one ! 11 11 May 2009 IBBTWRC-07 Workshop
  12. 12. Some Non-technical problems  Palestine / Israel  Cuba / USA  State monopoly / private industry  Poor / rich  Culture  Conservative / innovative  Cost of technology /cost of labour  International or national only Broadcast 12 11 May 2009 IBBTWRC-07 Workshop
  13. 13. Preparing a WRC 6 Regional Organisations:  CEPT (Europe)  RCC (ex Sovjet)  CITEL (N + S America)  APT (Asia)  League of ARAB States  ATU (Africa) 13 11 May 2009 IBBTWRC-07 Workshop
  14. 14. Agenda setting: Criteria  Worldwide or regional character  Need for changes in the RR  Required Studies should be completed   Resources required should remain manageable  Not yet at two successive preceding conferences 14 11 May 2009 IBBTWRC-07 Workshop
  15. 15. Agenda setting: Proposals Some standard items +  CEPT 22  Arab States 15  CITEL ≈ 14  RCC ≈ 10  USA ≈ 21  Many proposals from individual admin.’s  Much common, but still large variety 15 11 May 2009 IBBTWRC-07 Workshop
  16. 16.  CEPT: 1.17: to consider spectrum requirements and a global allocation to support cognitive radio systems in the context of heterogeneous radio networks environment, based on the results of ITU- R studies, in accordance with Resolution [EUR/ 10A25/12] (WRC-07)  ARAB: 1.10: to consider spectrum requirements and global allocation to support cognitive radio systems and/or radio software systems based on results of ITU-R studies 16 11 May 2009 IBBTWRC-07 Workshop
  17. 17. To Negotiate  On support, and priority  On text of Agenda Item and Resolution  CEPT : SDR in ITU-R Recommendations  ARAB: SDR in Agenda, or no agenda item 17 11 May 2009 IBBTWRC-07 Workshop
  18. 18. Interim result To consider spectrum related matters and regulatory measures to enable the introduction of cognitive radio systems and/or self configuring / software defined radio networks, based upon the results of ITU-R studies, in accordance with Resolution [EUR/10A25/12] (WRC-07) 18 11 May 2009 IBBTWRC-07 Workshop
  19. 19. Result  WRC-11 Agenda item 1.19: To consider regulatory measures and their relevance, in order to enable the introduction of software defined radio and cognitive radio systems based upon the results of ITU-R studies, in accordance with Resolution 956 (WRC-07)  Support by CEPT, ARAB, RCC  Neutral: Africa  No support from APT,  US, Can and Aus: can be done in SGs 19 11 May 2009 IBBTWRC-07 Workshop
  20. 20. Resolution 956 (WRC-07) resolves to invite ITU-R 1) to study whether there is a need for regulatory measures related to the application of cognitive radio system technologies; 2) to study whether there is a need for regulatory measures related to the application of software-defined radio, resolves further that WRC-11 considers the results of these studies and takes the appropriate actions. 20 11 May 2009 IBBTWRC-07 Workshop
  21. 21.   At ITU-R level – Working Party 1B of Study Group 1 Concerned groups: SG3, SG4, SG5, SG6, SG7   At CEPT level – CPG PTA 21 11 May 2009 IBBTWRC-07 Workshop
  22. 22.  CEPT will actively contribute to regulatory studies within the ITU-R to investigate this issue before defining any position on this Agenda Item.  Software-defined radio and cognitive radio system are not radio services as listed in Article 1 of the Radio Regulations.  Software-defined radio and cognitive radio system may be operated under any radio services.  Europe is of the view that frequencies or frequency bands (tuning range) for specific applications can be harmonised regionally by regional telecommunications organizations or on world wide basis in ITU-R Recommendations. 22 11 May 2009 IBBTWRC-07 Workshop
  23. 23. 1)  SDR and CRS are technologies that may allow more efficient use of the spectrum by any number of radiocommunications but are not radiocommunication services; such in accordance with RR No. 1.16; allocations are made only to radiocommunication services or the radio astronomy service; 2)  SDR and CRS are two capabilities related to equipment which can be combined. 3)  Comments from concerned groups. 23 11 May 2009 IBBTWRC-07 Workshop
  24. 24. WP 1B: Definition SDR A radio in which the RF parameters including, but not limited to, frequency range, modulation type, or output power can be set or altered by software, and/or the technique by which this is achieved. NOTE 1 – Excludes changes to operating parameters which occur during normal pre‑installed and predetermined operation of a radio according to a system specification or standard. NOTE 2 – SDR is implementation technique applicable to many technologies and standards. NOTE 3 – SDR techniques are applicable to both transmitter and receivers.” 24 11 May 2009 IBBTWRC-07 Workshop
  25. 25. WP 1B: Definition CRS (1) A radio system that has the capabilities: – to obtain the knowledge of radio operational environment and established policies and to monitor usage patterns and users’ needs; – to dynamically and autonomously adjust its operational parameters and protocols according to this knowledge in order to achieve predefined objectives, e.g. more efficient utilization of spectrum, and – to learn from the results of its actions in order to further improve its performance. 25 11 May 2009 IBBTWRC-07 Workshop
  26. 26. WP 1B: Definition CRS (2) NOTE 1 – Radio operational environment encompasses radio and geographical environments, and internal states of the Cognitive Radio System. NOTE 2 – To obtain knowledge encompasses, for instance, by sensing the spectrum, by using knowledge data base, by user collaboration, or by broadcasting and receiving of control information. NOTE 3 – Cognitive Radio System comprises a set of entities able to communicate with each other (e.g. network and terminal entities and management entities).” 26 11 May 2009 IBBTWRC-07 Workshop
  27. 27. 1) Analyse submitted contributions; 2) Review the studies and responses received from WP 5A and other relevant Study Groups and Working Parties; 3) Continue discussions on any potential regulatory implications, after identifying the regulatory issues and list of possible options for regulatory measures related to the introduction of SDR and CRS; 4) Develop potential pros and cons of options in the draft CPM text; 5) Develop draft CPM text 27 11 May 2009 IBBTWRC-07 Workshop
  28. 28. Milestones  4th WP 1B meeting [spring 2010]: Finalize draft CPM text before the deadline for its submission to the CPM Chapter Rapporteur;  16 July 2010 : Submission of draft CPM text to the CPM Chapter Rapporteur  21 July 2010: Submission of draft CPM text to BR Secretariat  8 October 2010: Extracts from Draft CPM Report to Special Committee  31 January 2011: Special Committee report to CPM-11  14 – 25 February 2011: CPM-11-2  [24 Oct. – 18 Nov. 2011 or 3 – 28 Oct. 2011]: WRC-11 28 11 May 2009 IBBTWRC-07 Workshop
  29. 29. 1 cognitive supporting pilot channel No further details/ proposals have been made for a CPC 2 database model Is that an ITU task, or the operators task 3 white space model may be a provision like: no interference, no protection 4 Probably a text to postpone the issue to WRC-15 ? 29 11 May 2009 IBBTWRC-07 Workshop
