Introduction CEPT/ECC has taken on-board a task to start investigations to assess requirements for future cognitive radio enabled SRDs. The investigations include this call for information from potential stakeholder and interested parties in the SRD community. It is expected that the CEPT Report in response to the 6th update process of the European Regulations on SRDs may rather present the initial results of these investigations and not include a proposal for a final regulatory approach/implementation but it is intended to make a step forward and this may lead to an implementation proposal in a second step. This work is based on a permanent Mandate from the European Commission; the CEPT is tasked with regularly updating of the technical Annex of EC Decision 2006/771/EC and its further amendments. The guidance letter to the CEPT includes the request to study cognitive radio enabled SRDs to start investigations on assessing the requirements for cognitive radio enabled SRDs and any potential implications in terms of SRD harmonised technical conditions, taking into account the on-going work in ETSI under mandate M/512 (Link). The ETSI Board adopted mandate M/512 on January 2013. In ETSI, TC RRS was nominated as the lead ETSI Technical Body for the mandate M/512 on Reconfigurable Radio Systems (6 Feb 2013). Other groups (OCG_RTTE, ERM, BRAN, MSG) have contributed to the mandate: • TC BRAN developed EN 301 598 on TV White Spaces; • TC RRS developed EN 303 144 on Cognitive Radio Systems and geo-location databases; Cognitive radio enabled SRDs may use opportunities for lower power applications to co-exist with other radio applications and services which use these frequencies already, and can be managed databases which identify where the white space opportunities are. This principle of 'geolocation', with better and more detailed databases, is at the heart of ideas to support access to locally unused space spectrum by cognitive devices i.e. cognitive as part of a wider system of management. The more autonomous element of 'cognitive' technique in radio transceivers is 'sensing', i.e. being able to detect what other signals are present and to respond accordingly to reduce the chance of interference. This principle is already used in techniques such as 'listen before talk' (LBT), and the Dynamic Frequency Selection (DFS) used in 5 GHz Radio Local Area Networks (RLANs) to ensure coexistence with radars. Most current practical considerations on where the Cognitive Radio would operate focus on overlaying its use on an existing, more conventional system. Cognitive is therefore seen as a 'secondary' usage, coexisting with itself and with the primary services. However, implementation of cognitive techniques could increase the effective capacity of bands designated for short-range devices. Cognitive techniques need to be analysed not only from the perspective of the technical feasibility but also from the perspectives of the demand, fit to application and investment requirements, the level of technical complexity involved, and the long term predictability of the spectrum access.

If no (Q2), are you planning to use cognitive radio enabled SRDs in the future? Yes No Why? For which application? If possible please fill out Question 3 5. Which applications do you consider as particularly suited to use a cognitive approach? Application(s) Why? 6. Which of the before mentioned (or other) cognitive techniques do you consider as mature enough? Mature enough? Not mature enough? Why? 7. Do the cognitive spectrum access techniques, listed below, suit your application(s)? a) geolocation database Yes No Why? b) autonomous sensing Yes No Why? c) beacon Yes No Why? 8. Do you see other polite spectrum access techniques than mentioned before? Yes No Please explain the techniques 9. Intra-SRD spectrum sharing studies can be seen as a pre-requisite for the successful implementation of a regulatory approach based on cognitive techniques. Do you agree YES/NO? Yes No Description of the situation Explain your answer Suggestion for CEPT to study 10. Concerning technical complexity: Do you think that cognitive radio enabled SRDs can compete in the market with less complex technical spectrum access solutions (e.g. duty cycle spectrum access could be understood as being less complex). Please explain your statement. Can compete Explain why Cannot compete Explain why 11. Cognitive techniques must also fit to the SRD application itself and the intentions in terms of quality and availability of the service. Do you agree? Please explain your statement. Where do you see the challenges? Yes No Please explain Where are the challenges? 12. Would you prefer an increase or a decrease in the number of spectrum access techniques (e.g. Duty Cycle, LBT, FHSS, DSSS, AFA, other cognitive techniques) in the regulations? Increase options Leave as it is Decrease Please explain your suggestion 13. In SRD deployment it is not possible to give each application its own reserved frequency slot. What do you think is important to achieve a good balance and operational reliance for the cognitive enabled SRDs? Comments 14. What are the most important operational/technical parameters for cognitive radio enabled SRDs (may depend on the SRD application)? Please explain Important operational parameters Please explain 15. Do you feel it is possible to enhance the existing SRD regulations to gain new frequency opportunities for cognitive radio enabled SRDs? Yes No Please specify your suggestion 16. Are there emerging market needs where cognitive radio enabled SRDs are in your opinion a viable alternative to satisfy the demand/ emerging market needs? Yes No Please explain Should these be treated as generic (non-specific) SRDs or as a specific type? 17. Do you have proposals and descriptions of modifications to technical parameters keeping in mind that the use of spectrum has to be as much as possible technology neutral meanwhile ensuring that other SRDs applications (including existing ones) have to share the same spectrum on equal basis and work properly so as to achieve new spectrum utilisation opportunities for cognitive enabled SRDs? Proposal 18. Any other suggestion? Proposal
