Role and Structure of ETSI RRS
• TC RRS’ main responsibility is to carry out standardization activities
related to Reconfigurable Radio Systems encompassing both Software
Defined Radio (SDR) and Cognitive Radio (CR).
• TC RRS has the following Working Group structure:
– WG1 focuses on “System Aspects” and develops proposals from a
system aspects point of view for a common framework in TC RRS;
– WG2 focuses on SDR technology with a particular interest in “Radio
Equipment Architecture” and proposes common reference architectures
for SDR/CR radio equipment;
– WG3 focuses on "Cognitive Management and Control"; the group
addresses functionalities for Reconfigurable Radio Systems which are
related to the Spectrum Management and Joint Radio Resource
Management across heterogeneous access technologies;
• WG4 focuses on “Public
ETSI TC RRS
Safety” and collects and
defines the related RRS

WG3:

WG4:

RRS Cognitive Radio Approach
• Centralized and Decentralized CR System (CRS) Concepts
• Objective: Provision of more efficient and flexible use of spectrum by
 Obtaining knowledge of the radio operational environment and location,
 Choosing modes of operation based on available information,
 Learning from the results obtained.
• Four CRS deployment
examples are being
studied:
 dedicated spectrum,
 shared spectrum,
 secondary usage in
dedicated spectrum,
 spectrum dedicated for
CRS.
• The ETSI RRS cognitive
radio system concept is
illustrated.

Cognitive Radio in the context of
Opportunistic Spectrum Usage
GSC16-GRSC9-07
 Use Cases have been developed for TV
White Space Usage, in ETSI TR 102 907.
These comprise:







Mid-/long range wireless access over TV WS,
Short range wireless access over TV WS,
Ad-hoc networking over TVWS,
Combined Ad-hoc networking and wireless access,
Sporadic use of TV WS,
Backhaul link using TV WS,
MBMS operating in TV WS.
 Normative System requirements are under
development in TS 102 946 “White Space
System requirements for Operation in UHF
TV Band”

Cognitive Radio / Reconfigurable
Radio in Heterogeneous Framework
GSC16-GRSC9-07
 RR in Mobile Devices: RRS has proposed the
SDR BB architecture illustrated
 BB Interface related work is in normative phase,
system requirements are defined in TS 102 969
 Opportunity: R&TTE Directive (the basic
regulatory framework in Europe for wireless
communication) is currently under revision.
The new revision is expected to allow for
usage of “RadioApps”, i.e. SW components
affecting radio characteristics of a MD.
 A further key requirement is “Dynamic ReCertificating” which is under development
in TR 102 967

Conclusions
• Cognitive Radio / Software Defined Radio Activities are
well advanced within ETSI RRS;
• RR work items focus on Mobile Device Architecture, a
reconfigurable BB architecture & Interface definitions
between distinct stakeholder domains (Device /
Component Manufacturer, etc.);
• CR work mainly focuses on opportunistic spectrum
acces, devices operating in a heterogeneous context –
exploiting opportunities related to revised R&TTE
Directive;
• Note that further activities are ongoing in STF386,
related to a development of cognitive interference
mitigation techniques for use by PMSE devices
