E3 – Overview
E3 is an European Project on End-to-End-Efficiency under the 7th Framework Program of the European Commission, addressing the core of the strategic objective "The Network of the Future"
Top Level Objectives:
• Cognitive Radio System design
• Gradual, non-disruptive evolution of wireless networks
• Increased efficiency of wireless network operations
Project Duration:
• Jan. 2008 – Dec. 2009

Cognitive Radio Aspects: Evolution
Important Cognitive Radio Aspects from industry perspective: � Evolution of B3G systems to Cognitive Radio Systems� Support of heterogeneous standards� More efficient Joint Radio Resource Management (Short term)
⇒ Access Selection: Select the best radio access for a given user/session based on service requirements, radio conditions, network load, policies

Flexible Use of Spectrum
Flexible use of spectrum
� Spectrum management for optimal spectrum usage
⇒ Dynamic Spectrum Allocation (DSA): • Spectrum control in the network
• Medium/long term radio resource optimisation
⇒ Dynamic Spectrum Selection (DSS): • Spectrum control entity in the terminal
• short term radio resource optimisation

Flexible use of spectrum (cont.)
� 3GPP LTE-Advanced could use such Dynamic Spectrum Access
⇒ So far, no opportunistic spectrum access is addressed in 3GPPspecifications because licensed spectrum is assumed
⇒ However, this may change for LTE-Advanced due to possibly up to 100 MHz bandwidth
⇒ Initial technical studies in 3GPP make more or less reference to cognitive concepts, e.g. Dynamic Spectrum Access
� IEEE 802.22 Wireless Regional Area Networks (WRAN)
⇒ Focus on broadband access in rural areas, up to 100 km cell size⇒ Uses spectrum of vacant DTV channels in the
VHF and UHF bands (between 54 MHZ and 862 MHZ)
⇒ Uses spectrum sensing & management for effective coexistence and radio resource sharing with licensed services
⇒ Regulation requires e.g. the secondary users to vacate the channel within 2 sec once primary user is detected.

More than Cognitive Radio: Self-X and Cognition in Radio Networks
Self-X: Self-configuration, Self-optimisation, self-healing⇒ for single-RAT networks
as well as heterogeneous networks⇒ Spectrum selection, inter-cell interference coordination⇒ Cell-outage compensation, cell self-reconfiguration⇒ Handover optimisation, load balancing
