COGNITIVE AND SOFTWARE DEFINED RADIO

at WRC -07 and -11

by Chris van Diepenbeek

Radiocommunications Agency of The Netherlands


ITU and WRC

 What is ITU  Why a WRC  Data and mechanics  Decision Process  Non-radio Problems


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


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


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


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


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


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


7 Committees

 1: Steering  2: Credentials  3: Budget  4, 5 and 6: On Substance

 Each of these creates Working Groups  7: Editorial


Negotiation process The formal process

The formal process is strictly hierarchical

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 !


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


Preparing a WRC

6 Regional Organisations:  CEPT (Europe)  RCC (ex Sovjet)  CITEL (N + S America)  APT (Asia)  League of ARAB States  ATU (Africa)


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


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


 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


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


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)


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


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.


  At ITU-R level – Working Party 1B of Study Group 1 Concerned groups: SG3, SG4,

SG5, SG6, SG7

  At CEPT level – CPG PTA


 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.


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.


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.”


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.


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).”


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


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


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 ?
