DOCUMENT #: GSC 13 -GRSC 6 -22 FOR: Presentation SOURCE: Dr Peter Olanders AGENDA ITEM: 4. 4 CONTACT(S): peter. olanders@ericsson. com Reconfigurable Radio Systems (RRS) in ETSI Dr Peter Olanders, ETSI TC RRS Chairman Presenter: Gabrielle Owen Submission Date: June 27, 2008

Highlight of Current Activities (1) • ETSI Board decided to create a Technical Committee for Reconfigurable Radio Systems (RRS) in January 2008 • The TC will study the feasibility of standardization activities related to Reconfigurable Radio Systems encompassing radio solutions related to Software Defined Radio (SDR) and Cognitive Radio (CR) research topics and present the results in the form of feasibility reports • Results within 2 years from start • Based on these feasibility reports, ETSI Board will then decide on possible continuation into actual standardization activities. • TC RRS is also to provide the ETSI main centre of expertise in the area of Reconfigurable Radio Systems 2

Highlight of Current Activities (2) • At ETSI TC RRS first meeting the chairman was appointed, and basic working structure agreed upon. • At the second meeting other officials were appointed as – secretary, vice-chair – working group chairmen • Terms of Reference and Work Items were approved as well • Actual technical work can start! • The Working Groups have already had their first meetings work has started! TC RRS Systems Aspects Equipment Architecture Functional Architecture and CPC Public Safety 3

Strategic Direction • The first period, maximum two years, work will focus on investigations on where, what and how standards in the areas of SDR and CR should be developed. • By collecting and defining the related Reconfigurable Radio Systems requirements from relevant stakeholders. • Liaisons with bodies in the area, as IEEE, SDR Forum and others working in the field of SDR and CR. • Fuel the gathered information into Feasibility Reports and ETSI Guides. 4

Challenges • SDR and CR are truly horizontal activities, thereby overlapping most radio systems as public broadcast, mobile (cellular) radio and private radio systems. • Public Safety and Defense have specific and very clear requirements on specifically SDR, and also CR. • The benefit of standards on SDR for some large market segments, as cellular systems, is not clear for all actors. • Full fledged CR does require complex and dynamic mechanisms, and thus powerful processing capability. Most probably, such CR is very long term. – short term solutions should be considered as well 5

Next Steps/Actions • Current plan is to produce a set of Technical Reports addressing a number of item within the subject matter like: – System aspects – Handset SDR Reference Architecture – Radio Base Station SDR status, implementations and costs aspects, including future possibilities – Functional Architecture – Cognitive Pilot Channel (CPC) design – Public Safety – glossary to define the terms "Cognitive Radio" and "Software Defined Radio" (following up on previous ETSI presentation to GSC on the matter). • On the results contained in these TRs further steps/actions will be decided. 6
