1 11 May 2009 IBBTWRC-07 Workshop

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


The formal process
Negotiation process

The formal
Plenary Plenary
process is
strictly
hierarchical
Committee Committee

WG WG

DG DG


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 ?

Thank you
