Transcript

  • 1. E3 Cognitive Radio: Industry Perspective Jens Gebert Alcatel-Lucent First IBBT-MIT Joint Workshop on Cognitive Radio Standardization & Markets May 11, 2009 Cognitive Radio: Industry Perspective Slide 1
  • 2. E3 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 May 11, 2009 Cognitive Radio: Industry Perspective Slide 2
  • 3. E3 E3 - Partners Network Equipment operators (4) manufacturers Bell Labs Germany (6) project coordinator End-to End Efficiency BUPT Regulators Academia / (4) research institutes (8) May 11, 2009 Cognitive Radio: Industry Perspective Slide 3
  • 4. E3Cognitive 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 3G Radio Operator 1 4G Radio Operator 2 WLAN May 11, 2009 Cognitive Radio: Industry Perspective Slide 4
  • 5. E3 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 Day 1: (Spectrum Operator A Operator B auction) Day X: Operator A Operator B ⇒ Dynamic Spectrum Selection (DSS): • Spectrum control entity in the terminal • short term radio resource optimisation May 11, 2009 Cognitive Radio: Industry Perspective Slide 5
  • 6. E3 Examples for Flexible Use of Spectrum Flexible use of spectrum (cont.) 3GPP LTE-Advanced could use such Dynamic Spectrum Access ⇒ So far, no opportunistic spectrum access is addressed in 3GPP specifications 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.

  • 7. E3 Reconfigurable Base Stations and Terminals Reconfigurable base stations ⇒ Base Station Configuration and Reconfiguration to maximise the networks efficiency Multi Standard Base Station UMTS LTE UMTS UMTS UMTS LTE 5 MHz LTE Multi Standard Base Station UMTS LTE UMTS LTE 15 MHz LTE Reconfigurable terminals May 11, 2009 Cognitive Radio: Industry Perspective Slide 7
  • 8. E3 Cognition Enablers Cognition enablers - Especially for environment with flexible spectrum management ⇒ Cognitive Pilot Channel • Distributes information on available radio accesses and their spectrum ⇒ Cognitive Control Radio • Exchange of Cognitive Control OPERATOR_INFO RAT_TYPE = GSM, UMTS, information between terminals RAT_LIST WiMAX, LTE… COVERAGE_EXTENSION = ⇒ Spectrum Sensing LOCAL/GLOBAL COVERAGE_AREA (optional) FREQ_LIST May 11, 2009 Cognitive Radio: Industry Perspective Slide 8
  • 9. E3 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 optimised radio parameters self- deployment operational of new self-optimisation mode configuration cells & nodes Performance monitoring May 11, 2009 Cognitive Radio: Industry Perspective Slide 9
