This paper introduces novel results in the area of Cognitive Radio System (CRS) aspects and Control Channels for Cognitive Information Sharing as they are currently elaborated in the framework of the ETSI Reconfigurable Radio Systems (RRS) Technical Body. An overview of the most relevant scenarios for CRS employing opportunistic spectrum usage in the TV White Spaces is given as well as an analysis of inherently required context information provisioning solutions. Finally, an overview on the related regulatory activities and future regulatory challenges are indicated with an emphasis on expected per-device certification mechanisms which will finally enable the introduction of “RadioApps”, i.e. software components provided to Mobile Devices (MD) which will affect the compliance of MDs to the essential requirements of the R&TTE Directive in Europe.
