This paper details the current work status of the ETSI Reconfigurable Radio Systems (RRS) Technical Committee (TC)
and gives an outlook on the future evolution. While previous publications have presented an overview of ETSI RRS¿ main
working axes related to i) Cognitive Radio System Aspects, ii) Radio Equipment Architecture (including a Cognitive Pilot
Channel (CPC) proposal and a Functional Architecture (FA) for Management and Control of Reconfigurable Radio Systems),
iii) Cognitive Management and Control and iv) Public Safety, this document focuses on latest progress related to UHF White
Spaces work and the definition of an SDR Handset Architecture.
In particular, it is outlined how Cognitive Radio principles can help to adapt existing and/or evolving Radio Standards, such as
3GPP Long Term Evolution, to a possible operation in UHF White Space bands.
