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.

May 2010 Introduction (1/3) 802.19.1 system architecture consists of three logical entities and six logical interfaces 802.19.1 system architecture Hyunduk Kang et al, ETRI

May 2010 Introduction (2/3) In order to start theirs operation, TVBDs or networks should select a proper operating channel among allowed channels Allowed channels that may be used by TVBDs or networks at a given location will be given by TVWS database. For example, in the U.S. allowed channels are as follows; However, status of given allowed channels will be dynamically changed based on incumbent activities, other TVBDs or networks activities, relocation of TVBDs, and so on. Hyunduk Kang et al, ETRI Hyunduk Kang, ETRI

May 2010 Introduction (3/3) To facilitate coexistence between 802.19.1 compliant TVBDs or networks, each logical entities should know status of TV channels at a given location such as; Which channel is available for TVBDs or networks Which channel is disallowed by regulation, or by the request of incumbents Which channel should be protected due to incumbent activity Which channel should be restricted with limitations in order to use by TVBDs or networks Which channel is already being used by other TVBDs or networks Etc. Using status of TV channels at a given location, a CM shall select a proper operating channel to mitigate coexistence problems among 802.19.1 compliant TVBDs and networks Hyunduk Kang et al, ETRI

Definitions of Channel Classification (1/3) May 2010 Definitions of Channel Classification (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. Slide 7 Hyunduk Kang et al, ETRI

Definitions of Channel Classification (2/3) May 2010 Definitions of Channel Classification (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 8 Hyunduk Kang et al, ETRI

Definitions of Channel Classification (3/3) May 2010 Definitions of Channel Classification (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.

Venn diagram of TV Channels (2/2) May 2010 Venn diagram of TV Channels (2/2) Disallowed set A subset of a TV channel set A complementary set of the allowed set Allowed set A complementary set of the disallowed set Available/Restricted/Protected/Unclassified set A subset of the allowed set Two different channel sets are a complementary set each other Operating set A subset of the available set or the restricted set or union of both A subset of a complementary set of the coexistent set Coexistent set A subset of the operating set Hyunduk Kang et al, ETRI
