ETSI Tutorial


Presented by Markus Mueck, Infineon Technologies Germany, and Andrea Lorelli, ETSI France

The objective of this tutorial is to enable the participant

• To understand the ETSI framework with a particular focus on the ETSI Reconfigurable Radio Systems (RRS) Technical Committee. Information will be given on the possible deliverables to be produced (Technical Reports (TR), Technical Specifications (TS), European Norm (EN), etc.) and the possibilities for interacting with ETSI RRS;

• To understand the ETSI RRS vision related to Cognitive Radio (CR) and Software Defined Radio (SDR). In particular, the proposed solutions elaborated in the various Working Groups (WGs) are detailed and discussed: o WG1 focuses on "System Aspects" and develops proposals from a system aspects point of view for a common framework in TC RRS with the aims to guarantee coherence among the different TC RRS WGs and to avoid overlapping and gaps between related activities; o WG2 focuses on SDR technology with a particular interest in "Radio Equipment Architecture" and proposes common reference architectures for SDR/CR radio equipments (mobile handset devices, radio base stations, etc.), related interfaces, etc; o WG3 focuses on "Cognitive Management and Control"; the group collects and defines the system functionalities for Reconfigurable Radio Systems which are related to the Spectrum Management and Joint Radio Resource Management across heterogeneous access technologies. Furthermore, the group has developed a Functional Architecture for the Management and Control for Reconfigurable Radio Systems as well as a report on the Cognitive Pilot Channel as an enabler to support the management of the RRS; o WG4 focuses on "Public Safety" and collects and defines the related RRS requirements from relevant stakeholders in the Public Safety and Defense domain. The group defines the system aspects for the applications of RRS in Public Safety and Defense. In the framework of this tutorial, it will be illustrated how ETSI RRS will complement ongoing effort in other bodies (building on the structure outlined above), such as IEEE standardization bodies, by proposing technological solutions beyond the existing scope (related to SDR interfaces, CR specific Management and Control architectures and interfaces, knowledge management via a Cognitive Pilot Channel and Security solutions); furthermore, ETSI RRS fulfills a key role in the framework of European Regulation, with a focus, among other aspects, on the following: - The R&TTE Directive regime in force in Europe is based on declaration of conformity and does include neither type approval nor registration of the equipment nor equipment identifier (in the US, type approval is still necessary). This self-declaration is preferably a reference to a Harmonised Standard to be developed by ESTI RRS. - Protection of TV bands: In Europe, DVB-T does not show a residual carrier as it is the case in the US (the possibility for detection of the US ATSC signal below noise (i.e., at -114 dBm) is made possible thanks to the residual carrier which is present in the ATSC signal). A corresponding adaptation of sensing based standards needs to be defined for Europe. - Broadcasting, wireless microphones and assignment to radio stations are managed in Europe at the national level. Any sharing scheme based on a database will require some level of integration of the national data. In order to address the above and other European Regulatory aspects, the Electronic Communications Committee (ECC) within the European Conference of Postal and Telecommunications Administrations (CEPT) has set up the SE43 group working on "Technical and operational requirements for the operation of cognitive radio systems in the 'white spaces' of the frequency band 470-790 MHz". ETSI RRS is the competence center within ETSI to implement those regulatory requirements.

• To understand ongoing interactions with regulatory bodies and possibilities for impacting related actions via ETSI RRS; • To understand the most relevant future study axes, related to commercial and military related applications of CR and SDR.
