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 is building on 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 equipments;
• 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;

• Objective: Provision of more efficient and flexible use of spectrum by Obtaining knowledge of the radio operational environment and location, Deciding on the gathered information and acting based on this decision, Learning from the results obtained.
• Four CRS deployment examples are proposed:
dedicated spectrum, shared spectrum, secondary usage in
dedicated spectrum, and spectrum dedicated for
CRS.
• The overall ETSI RRS cognitive radio system concept is shown on the right hand side. 4

CPC Scope: The Cognitive Pilot Channel (CPC) serves mainly to support the user terminal for an efficient discovery of the available radio accesses in a heterogeneous wireless environment.
FA Scope: Network with heterogeneous access technologies Reconfigurable UEs / Mobile Devices and Reconfigurable Base Stations;
Functional Architecture addresses generic framework on possible SON (3GPP TS 36.300) evolution concepts, etc.
New activities started on TV White Spaces. 5
Software Defined Radio Activities SDR in Mobile Devices: RRS has proposed the
SDR architecture illustrated on the right hand side with the following capabilities:
• Multiradio configuration capability;• Multiradio operation capability;• Multiradio resource sharing capability.
Interface definitions are currently ongoing.
SDR in Reconfigurable Base Stations: The following general requirements are derived:
• Transition from one standard to a new;• Multi-standard use, frequency re-farming;• Spectrum trading & secondary spectrum usage;• Dynamic capacity optimization depending on load;• Network planning and adaptation, antenna tuning;• Backhaul reconfiguration for flat architecture. 6
Related Activities in TC ERM / STF 386
Development of cognitive interference mitigation techniques for use by PMSE devices (Programme Making and Special Events)
Achieve co-existence of high audio quality PMSE devices using often a 100% transmitter duty cycle emission profile with victim radio services such as Services in L-Band or Broadcast Services and future Land Mobile Services and applications in UHF frequency range that is currently under investigation under the “Digital Dividend” discussions in EC, ECC and ETSI fora
See also separate presentation on cognitive-PMSE (C-PMSE).

Conclusions
Cognitive Radio / Software Defined Radio Activities are well advanced within ETSI;
SDR mainly focuses on Mobile Device Architecture & Interface definitions between distinct stakeholder domains (Device / Component Manufacturer, etc.);
CR mainly focuses on devices operating in a heterogeneous context, flexible & dynamic spectrum/resource management and TV White Space operation as a future topic;
There are close ties between TC RRS and TC ERM & STF386 on cognitive interference mitigation techniques for use by PMSE devices .
