Patent Policy and Procedures: The contributor is familiar with the IEEE Patent Policy and Procedures < 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 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.

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 operation

4. 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

5. 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 standard
This will be mentioned in reference model (5.3)
If there is a need to define some specific mechanisms describing how interface is used by , this shall be in 10.2
Otherwise, 10.2 is not needed

6. 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 system

7. 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

8. 10.5 Self-coexistence mechanisms
10/01/2019
10.5 Self-coexistence mechanisms
This subsection was planned as a place to describe how different 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

9. 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, , 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 (10.6 can be deleted and reference to standard can be done in reference model (5.3))
