2. Highlight of Current Activities
Most activity about reconfigurable radio systems (RRS), including cognitive radio (CR) and software defined radio (SDR), has been conducted in ETSI, IEEE, and ITU-R. Other contributions come from groups including the Wireless Innovation Forum
Working definitions of SDR and CR were adopted in 2009
ITU-R WP1B is the responsible group for WRC-11 AI 1.19
ITU-R WP5A is developing a report on a definition for CRS and input for WP1B
ITU-R WP5D is giving input to WP5A on CR related to IMT/3G
Market and regulatory issues, including potential benefits and potential complications, are also being studied

3. Current Activities – ITU-R
Website:
Most work related to RRS is done in SG1 (Spectrum Management) and SG5 (Terrestrial Services)
Selected SG1 WP1A work
[39] Annex 11 - Studies on cognitive radio systems (CRS) in relation to Resolution ITU-R 58 within Working Parties 1A and 1B
Selected SG1 WP1B work
[42] Annex 14 - Studies on cognitive radio systems (CRS) in relation to Resolution ITU-R 58 within Working Parties 1A and 1B
[42] Annex 01 - Preliminary draft revision of Recommendation ITU-R SM Design guidelines for developing automated spectrum management systems

4. Current Activities – ITU-R
Selected SG5 WP5A work
[198] Annex 22 - Working document towards a preliminary draft new Report ITU-R [LMS.CRS2] - [Cognitive radio systems [(CRS) applications] in the land mobile service]
[198] Annex 20 - Working document towards a preliminary draft revision of Report ITU-R M Advanced intelligent transport systems (ITS) radiocommunications

5. Current Activities – IEEE

7. Strategic Direction
Provide relevant strategic direction of the PSO on the topic, including observations (positive or negative), outcomes, target timeframes, collaborations, etc., for completion that the PSO foresees on the topic. During the GSC interactive panel, please be prepared to discuss the significance and potential impact of the strategic approach that the PSO is taking on this HIS.

8. Challenges (1)
The market is moving very fast, complicating standardization
Debate continues over the role of standards in RRS
What needs to be standardized? Will setting standards so early in RRS development hurt innovation?
Several technologies are competing for de facto standard status
Regulatory bodies need to make sure that devices will meet current and future requirements
Most interest has been on the business and technology sides, but mature policy is also necessary for RRS to succeed
A conformity assessment apparatus is necessary
Regulators also need principles for considering questions unique to RRS
Example: whether to allow software updates without requiring a device to be recertified

9. Challenges (2)
Existing services (especially public safety) need protection from interference that might result from SDR and CRS
Some standards and/or regulatory entities might want to exclude SDR/CRS from some bands
Some countries (e.g., the U.S., Canada) have not recommended regulatory changes or changes to ITU rules before RRS can be implemented, but other countries might
On the technology side, standards are needed for components that make CR networks secure from various kinds of DoS attacks, a generalized CR-MAC, and cross-layer design
Despite all of the efforts, the real need for vehicle manufacturers is the ability to build vehicles with radios that can be updated for new protocols over the life of the vehicle.

10. Next Steps / Actions
Identify plans for the future, path forward, etc., and/or identify next steps/actions to be taken by the PSO.
