3Role 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
- WG4 focuses on Public Safety and collects and
defines the related RRS requirements from
relevant stakeholders in the Public Safety and
Defense domain.
4RRS 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, - 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.
5Cognitive Pilot Channel (CPC) Functional
Architecture (FA) in RRS
- 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.
6Software 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.
7Related 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).

8Conclusions
- 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 .
