      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
                                                               WG2:
           requirements from relevant             WG1:     Reconfigurable

                                                                               Cognitive
                                                                                            WG4:

                                                                                 GSC16-GRSC9-07


       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.

     Opportunistic Spectrum Usage
      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”

Radio in Heterogeneous Framework
 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 Re-
      Certificating” 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
         (Programme Making and Special Events)
