The present document provides summary of the feasibility studies and work carried out by TC-RRS and its Working Groups since January 2008. The Working Groups are responsible for following study areas:
• WG1: RRS System Aspects.
• WG2: Reconfigurable Radio Equipment Architecture.
• WG3: Functional Architecture and Cognitive Pilot Channel (in Cognitive Radio Network Management).
• WG4: RRS Public Safety.
Furthermore, aspects not covered by the RRS Working Groups have also been added, see clause 6.
As a whole these studies have covered radio system technologies more generally known as Software Defined Radio and Cognitive Radio. The present document contains proposals for standardization in this area.
