overview
Overview
  • Role and Structure of ETSI RRS
  • Cognitive Radio Activities in RRS – deployments:
    • dedicated spectrum,
    • shared spectrum,
    • secondary usage in dedicated spectrum, and
    • spectrum dedicated for CRS.
  • Cognitive Radio in the context of Opportunistic Spectrum Usage
  • Cognitive Radio / Reconfigurable Radio in Heterogeneous Framework
  • Conclusions
role and structure of etsi rrs
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 Safety” and collects and defines the related RRS requirements from relevant stakeholders in the Public Safety and Defense domain.
rrs cognitive radio approach
RRS Cognitive Radio Approach
  • 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.
  • Centralized and Decentralized CR System (CRS) Concepts
  • 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
  • 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”

  • 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
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)
