Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures http://standards.ieee.org/guides/bylaws/sb-bylaws.pdf 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 Chair Carl 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 802.22 Working Group.

(Candidate) Functions of SM July 2007 (Candidate) Functions of SM SM in BS Management functionalities in CPE Channel Set Information - Maintain/Updated Channel sets based on information collected from its sensing function, its associated CPEs, Incumbent database, , Geo-location. -Inform CPEs of changes in Channel sets Maintain a local copy of channel set info Update channel set information as directed by the BS and as a result of in-band/out-of-band sensing Control Spectrum sensing related message - Send commands to its SSF and to CPEs’ SSFs (Sensing Request Command) Receive sensing reports from the MAC (local reports and reports from CPEs) Control the scheduling of the quiet periods -Request SSF in the CPE to sense out-of-band channels, when not explicitly requested by the BS. Channel Management - Channel management commands - Controls the selection of operating and backup channels based on information collected from its sensing function, from its associated CPEs, and from Incumbent databases. Rest of Function Protection of incumbent Self-co-existence Spectrum sharing -Cap of TPC -DFS management -Inter network communication Kyutae Lim, GEDC, Georgia Tech
