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

• WG4 focuses on Public Safety and collects and
  defines the related RRS requirements from
  relevant stakeholders in the Public Safety and
  Defense domain.

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,
• 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.

Cognitive 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.

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.

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 .
