11. This standard specifies policy language (PL) requirements and policy architecture (s) for policy-based dynamic spectrum access (DSA) radio systems. In this standard, a distinction is made between the policy reasoning that is accomplished within the Policy Based Radio (PBR) node and policy generation and validation that is accomplished through a policy generation system prior to provision of the policy to the PBR node. Policy reasoning may be distributed, i.e., it may take place either within a PBR node or in other elements of a policy based radio communications network. 11 IEEE 1900.5 System Architecture Source: “IEEE Standard for Policy Language Requirements and System Architectures for Dynamic Spectrum Access Systems,” IEEE Std 1900.5™-2011, 13 January 2012 Doc #: 5-14-0001-00-subs8/17/2015

12. Requirements from IEEE 1900.5 (there are many more) In order to evaluate policy languages options, it is important to know what the basic requirements are for the language. These were determined in developing IEEE 1900.5: – A declarative language shall be used. – A policy language shall have clear and unambiguous syntax and semantics. – The policy language shall have the capability for annotations. – The policy language shall have a machine-understandable syntax. – The policy language may have an easily human understandable syntax. – The policy language shall support permissive policies and restrictive policies. – The policy language shall be capable of expressing inheritance and extension of policies. – The language shall be capable of specifying the dynamics (behaviors), including temporal aspects, of policy based dynamic spectrum access radio system components. – The policy language shall include the ability to introduce definitions of new functions in terms of other known functions and allow inferring relationships between two functions, such as whether two functions are equivalent or not. – The expressivity of the policy language shall include the following: Classes, Individuals, Binary relations, Composition of relations, Functions, Temporal aspects of the system, Behavioral descriptions, State of the system, and Rules) – The policy language shall be explicit about which negation [logical negation or negation as failure (NAF)] it supports. 8/17/2015Doc #: 5-14-0001-00-subs12 Source: “IEEE Standard for Policy Language Requirements and System Architectures for Dynamic Spectrum Access Systems,” IEEE Std 1900.5™-2011, 13 January 2012

13. IEEE P1900.5.1 Title – Standard Policy Language for Dynamic Spectrum Access Systems. Scope – This standard defines a vendor-independent policy language for managing the functionality and behavior of dynamic spectrum access networks based on the language requirements defined in the IEEE 1900.5 standard. The standard developed under this PAR will take into consideration both the Policy Language Requirements of IEEE 1900.5 and the results of the Modeling Language for Mobility Work Group (MLM-WG) within the Wireless Innovation Forum (SDRF v2) Committee on Advanced Wireless Networking and Infrastructure. MLM-WG is developing use cases, an ontology, corresponding signaling plan, requirements and technical analysis of the information exchanges that enable next generation communications features such as spectrum awareness and dynamic spectrum adaptation, waveform optimization, capabilities, feature exchanges, and advanced applications. The MLM-WG expects this effort to lead to specifications/standards for languages and data exchange structures to support these capabilities..

15. IEEE P1900.5.2 Title – Standard Method for Modeling Spectrum Consumption Scope – This standard defines a vendor-independent generalized method for modeling spectrum consumption of any type of use of RF spectrum and the attendant computations for arbitrating the compatibility among models. The methods of modeling are chosen to support the development of tractable algorithms for determining the compatibility between models and for performing various spectrum management tasks that operate on a plurality of models. The modeling methods are exclusively focused on capturing spectrum use but are defined in a schema that can be joined with other schemata of business processes of spectrum management or behavioral aspects of spectrum policy.
