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.

Background
According to Open Call for Contributions of IEEE WG, topics related to cognitive plane are categorized as having the first priority, which must be defined in the draft standard before it is ready for Sponsor Ballot.
However, according to the latest Draft Standard--IEEE P1900.7™/D2, Oct and related WG documents, no proposal on cognitive plane has been submitted so far.
This presentation serves as the first (preliminary) proposal for the cognitive plane in IEEE

4. Current Status Cognitive Plane in IEEE 802.22

Current Status
Cognitive Plane in IEEE
IEEE Std ™-2011, July 2011
The system model in IEEE Std is a point-to-multipoint model for extending broadband access to less populated rural areas. In this model, the base station (BS) is assumed to control all RF parameters of its associated customer premises equipment (CPE) (frequency, modulation, etc.) in a “master-slave” relationship.
The Protocol Reference Model (PRM) of IEEE keeps the usual data and management/control plane functionality intact, while creating a new cognitive plane to support the cognitive radio capabilities.
The cognitive plane consists of all the that relate to cognitive functions.

5. An Overview of Cognitive Plane in IEEE 802.22
14/11/2018
An Overview of Cognitive Plane in IEEE
Cognitive Functions
Capabilities/Tasks
Spectrum Manager (SM) BS
The SM is responsible for the most important tasks, such as maintaining spectrum availability information, channel selection, channel management, scheduling spectrum sensing operation, access to the database, enforcing IEEE and regulatory domain policies, and enabling self-coexistence, etc.
Spectrum Sensing Automaton (SSA)
BS/CPE
The SSA interfaces to the Spectrum Sensing Function (SSF) and executes the commands from the SM to enable spectrum sensing.
Spectrum Sensing Function (SSF)
Spectrum sensing is the process of observing the RF spectrum of a television channel to determine its occupancy (by either incumbents or other WRANs)
Geolocation (GL)
GL module shall provide the information to determine the location of the IEEE device (BS or CPE)

IEEE vs. IEEE
According to Project Authorization Request (PAR) of IEEE :
P is for Radio Interface for White Space Dynamic Spectrum Access Radio Systems Supporting Fixed and Mobile Operation
Compared to IEEE , IEEE is expected to have the following new features:
Full mobility support including handover
Support of mesh topology
Support of multiple frequency channels including non- adjacent channels
Power efficiency for mobile and low power users
Support of inter-system coexistence.

9. Requirements on Proposals for Cognitive Plane in IEEE 1900.7
14/11/2018
Requirements on Proposals for Cognitive Plane in IEEE
According to Open Call for Contributions of IEEE :
Access to white space (WS) database (first priority)
Maintain spectrum availability information (first priority)
Self-coexistence mechanisms (first priority)
Mechanisms for coexistence with other WS networks (first priority)
Spectrum sensing management (second priority)
Frequency bands, time slots, and power assignment (second priority)
First priority topic must be defined in the draft standard before the draft standard is ready for Sponsor Ballot.
Second priority topic is desired to be in the draft standard but the lack of it does not stop the draft standard to go to Sponsor Ballot.
