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 IEEE’s name any IEEE Standards publication even though it may include portions of this contribution; and at the IEEE’s 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 DYSPAN SC. Patent Policy and Procedures: The contributor is familiar with the IEEE 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 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 <harada@nict.go.jp> 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 IEEE DYSPAN SC.

10/01/2019 Outline Introduction Cognitive plane section Slide 2

10/01/2019 Introduction As was discussed during December meeting, it would be beneficial to describe what contents is expected inside Cognitive Plane section of the draft This contribution gives such explanation for each subsection of the Cognitive Plane section This contribution is intended to set some directions, not to limit contributions to the section However, contributions shall be within the scope of the PAR PHY layer and MAC sublayer Interfaces/SAPs with other layers and management/control plane Some parts of management/control plane (including cognitive plane) that are needed to be defined in the draft for proper 1900.7 operation Slide 3

10/01/2019 10.1 Access to WS database It has been decided during Singapore meeting that interface with WS database is implementation dependent It is better to mention this in reference model (5.3) and delete 10.1 because nothing new can be written there Slide 4

10.2 Spectrum sensing management 10/01/2019 10.2 Spectrum sensing management It has been decided during Singapore meeting that interface with spectrum sensing device will follow 1900.6 standard This will be mentioned in reference model (5.3) If there is a need to define some specific mechanisms describing how 1900.6 interface is used by 1900.7, this shall be in 10.2 Otherwise, 10.2 is not needed Slide 5

10.3 Maintaining spectrum availability information 10/01/2019 10.3 Maintaining spectrum availability information WS frequency bands are used on a secondary basis and are shared with other systems Current operating channel(s) may need to be released Different channels are not equal due to different limitations (by regulation) and interference conditions (due to other systems operation) 10.3 may describe how to select/prioritize available channels for proper/better operation of 1900.7 system Slide 6

10.4 Frequency bands, time slots, and power assignment 10/01/2019 10.4 Frequency bands, time slots, and power assignment This subsection was assuming TDMA and does not make sense for CSMA Can be deleted Slide 7

10.5 Self-coexistence mechanisms 10/01/2019 10.5 Self-coexistence mechanisms This subsection was planned as a place to describe how different 1900.7 systems coexist with each other In case of CSMA, not sure we can add anything new here (on top of what is already in previous sections) Looks like can be deleted Slide 8

10.6 Mechanisms for coexistence with other WS networks 10/01/2019 10.6 Mechanisms for coexistence with other WS networks WS frequency bands can be shared by several secondary systems. This may create interference that may cause considerable degradation to system performance. There is a need for different systems (1900.7, 802.11, 802.22 etc) to coexist with each other Several options are possible: We can define such mechanisms in the draft We can leave them implementation dependent (10.6 can be deleted and no need to mention anything) We can use some existing standard like 802.19.1 (10.6 can be deleted and reference to standard can be done in reference model (5.3)) Slide 9
