The material in this document is subject to change in form and content after further study. The contributor(s) reserve(s) the right to add, amend or withdraw material contained herein. Release: The contributor grants a free, irrevocable license to the IEEE to incorporate material contained in this contribution, and any modifications thereof, in the creation of an IEEE Standards publication; to copyright in the IEEEs name any IEEE Standards publication even though it may include portions of this contribution; and at the IEEEs sole discretion to permit others to reproduce in whole or in part the resulting IEEE Standards publication. The contributor also acknowledges and accepts that this contribution may be made public by IEEE Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures including the statement "IEEE standards may include the known use of patent(s), including patent applications, provided the IEEE receives assurance from the patent holder or applicant with respect to patents essential for compliance with both mandatory and optional portions of the standard." Early disclosure to the Working Group of patent information that might be relevant to the standard is essential to reduce the possibility for delays in the development process and increase the likelihood that the draft publication will be approved for publication. Please notify the Chairhttp://standards.ieee.org/guides/bylaws/sb-bylaws.pdf Carl R. StevensonCarl R. Stevenson as early as possible, in written or electronic form, if patented technology (or technology under patent application) might be incorporated into a draft standard being developed within the IEEE Working Group.

2 doc.: IEEE /0267r0 Submission June 2007 Wendong Hu, STMicroelectronicsSlide 2 Abstract The presentation describes the functions and interfaces of the Spectrum Manager entity in a proposed reference architecture for IEEE

3 doc.: IEEE /0267r0 Submission June 2007 Wendong Hu, STMicroelectronicsSlide 3 A Proposed Reference Architecture and the Spectrum Manager

4 doc.: IEEE /0267r0 Submission June 2007 Wendong Hu, STMicroelectronicsSlide 4 Proposed Reference Architecture PHY Spectrum Sensing Function –A part of the PHY MAC –MAC Common Part Sub-layer –Convergence Sub-layer Spectrum Manager –A part of the MAC Spectrum Usage Policy Module Geo-location Database Higher Layer –Bridge, router, host, etc.

5 doc.: IEEE /0267r0 Submission June 2007 Wendong Hu, STMicroelectronicsSlide 5 Spectrum Manager – The Functions Spectrum Sensing Management Spectrum Pooling –Channel sets (pool) Management Spectrum sharing –Opportunistic –Negotiation-based Inter Network Communications –Over-the-air –Over-the backhaul DFS Management TPC Management Adaptive Modulation Management Adaptive Beam-Forming Management

6 doc.: IEEE /0267r0 Submission June 2007 Wendong Hu, STMicroelectronicsSlide 6 Spectrum Manager – The Interfaces (1) With the Spectrum Usage Policy module –Receive – Spectrum Usage policies With the Geo-location Database –Receive – Geo-location information With the Spectrum Sensing Function –Send – spectrum sensing control messages Parameters: channel, time, duration, method used, etc. –Receive – spectrum sensing reports With the MAC Common Part –Send – Spectrum Pool (channel set) status information –Receive – Spectrum demands (QoS / Throughput requirements)

7 doc.: IEEE /0267r0 Submission June 2007 Wendong Hu, STMicroelectronicsSlide 7 Spectrum Manager – The Interfaces (2) With the PHY –Send/Receive – DFS control –Send/Receive – TPC control –Send/Receive – Over-the-air inter-network communication (Beaconing) control –Send/Receive – Adaptive modulation control –Send/Receive – Adaptive beam forming control With the Higher Layer –Send/Receive – Over-the-backhaul inter-network communication (Bridging) control. –Send – Spectrum Pool (channel set) status information –Receive – Spectrum demands (QoS / Throughput requirements)
