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
<[email protected]> 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. If you have questions, contact the IEEE Patent Committee Administrator at <[email protected]>.

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)
•
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
•
Unclassified set
– A set of channels occupied by incumbents to be protected
– Can NOT be used by any TVBDs or networks
– A set of channels has not been classified as one of listed above three sets

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)
• 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

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

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
