Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures <http:// ieee802.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 TAG 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 <shellhammer@ieee.org> 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 802.19 TAG.

Channel Classification Revisit (1/3) July 2010 Channel Classification Revisit (1/3) Disallowed set A set of channels disallowed for any TVBDs or networks by regulation, or by the request of incumbents E.g., in the U.S. TV channel 3,4, and 37 are disallowed by regulation E.g., in the U.S. a TV channel registered at TVWS database by a licensed wireless microphone is disallowed for any TVBDs or networks Might be provided by TVWS database and will be updated if necessary Allowed set A set of channels allowed for TVBDs or networks Should be provided by TVWS database and will be updated if necessary All TVBDs or networks should first obtain a list of the available channels before operating.

Channel Classification Revisit (2/3) July 2010 Channel Classification Revisit (2/3) Available set A set of free channels available for TVBDs or networks Restricted set A set of channels restricted to use with limitations due to regulation Can be used by TVBDs or networks under limited conditions predefined by regulation E.g., in the U.S. a portable/personal TVBD can use “the first adjacent channel of the incumbent activating channel” with limited transmit power (≤ 40mW EIRP) by FCC regulation E.g., in the U.S. channel 36 and 38 need more stringent emission mask to protect incumbents in channel 37 by FCC regulation Protected set A set of channels occupied by incumbents to be protected Can NOT be used by any TVBDs or networks Unclassified set A set of channels has not been classified as one of listed above three sets Slide 5 Hyunduk Kang et al, ETRI

Channel Classification Revisit (3/3) July 2010 Channel Classification Revisit (3/3) Operating set A set of operating channels being used by one TVBD or network Can be selected from available set or restricted set only if there are no incumbent activities on it If each TVBD or network has its own operating channel, spectrum etiquette with FDM (frequency division multiplexing) is achievable. Coexistent set A set of channels being shared by two or more TVBDs or networks If two or more TVBDs or networks compete the same channel, spectrum etiquette with FDM is NOT achievable.

Channel Set Transition Events (1/3) September 2009 Channel Set Transition Events (1/3) Event (1): If the channel already being used by one TVWS system is assigned to other TVWS system(s) so that two or more TVWS systems use the same channel as an operating channel Event (2): If the channel is released by other TVWS systems so that the channel is being used by only one TVWS system Event (3): If the channel is released and not be used by any TVWS systems due to the completion of its usage Event (4): If the channel is assigned to one TVWS system and not shared by any other TVWS systems Hyunduk Kang et al, ETRI

Channel Set Transition Events (2/3) September 2009 Channel Set Transition Events (2/3) Event (5): If the channel is assigned to two or more TVWS systems at the same time Event (6): If an incumbent activity has been informed on the channel Event (7): If the channel temporarily satisfies the condition that requires its usage with limitations due to regulation E.g., in the U.S. if an incumbent activity has been informed on the channel (F), the first adjacent channel (F±1) can be used by only a portable/personal TVBD with limited transmit power, say 100mW EIRP Event (8): If the channel is released by an incumbent due to the completion of its usage Hyunduk Kang et al, ETRI

Channel Set Transition Events (3/3) September 2009 Channel Set Transition Events (3/3) Event (9): If the channel is exempted from its temporary restriction and free to use without limitation E.g., in the U.S. if the channel is released by the incumbent on the channel (F) due to the completion of its usage, the first adjacent channel (F±1) can be used by any TVBDs and networks Event (10): If the channel is not occupied by an incumbent or any TVWS systems Event (11): If the channel is not classified or updated within the predefined time expiration Hyunduk Kang et al, ETRI
