IEEE 1900.1 Working Group on Definitions and Concepts • IEEE 1900.1 Title: Standard Definitions and Concepts for Dynamic Spectrum Access: Terminology Relating to Emerging Wireless Networks, System Functionality, and Spectrum Management • P1900.1 Scope:This standard provides definitions and explanations of key concepts in the fields of spectrum management, cognitive radio, policy-defined radio, adaptive radio, software-defined radio, and related technologies. The document goes beyond simple, short definitions by providing amplifying text that explains these terms in the context of the technologies that use them. The document also describes how these technologies interrelate and create new capabilities while at the same time providing mechanisms supportive of new spectrum management paradigms such as dynamic spectrum access. • Purpose:New concepts and technologies are rapidly emerging in the fields of spectrum management, policy-defined radio, adaptive radio, software-defined radio, reconfigurable radio, and networks and related technologies. Many of the terms used do not have precise definitions or have multiple definitions. This document facilitates the development of these technologies by clarifying the terminology and how these technologies relate to each other. • Status: Published 26 September 2008 Informal Briefing to SDR Forum MLM Work Group
Objectives of the IEEE 1900.1 Standard • P1900.1 is a repository of KEY definitions for SCC 41 • P1900.1 includes global definitions, i.e., terms that cross SCC 41 WG boundaries • P 1900.1 should not include local definitions, i.e., there are some definitions that are provided in documents produced by another IEEE 1900 WG that are not needed in IEEE P1900.1 if they do not involve multiple WGs. • Informative Text • Because of the complexity of some of the terms and the interrelationship of many of the terms, informative text is provided to elaborate on key concepts. Informal Briefing to SDR Forum MLM Work Group
Sources of New Definitions in the IEEE 1900.1 Standard • New terms and associated definitions generated by IEEE 1900.1 • New definitions generated by IEEE 1900.1 for existing terms • New terms and definitions generated by other WGs under SCC 41 • Example: Study Group A generated a definition for the term “Spectrum Access Behavior” • Inclusion of Terms and Definitions from other organizations (e.g., ITU, IEEE, regulatory bodies) • Subjective judgment was used as to what external terms to include; the guiding principle is that inclusion of these external definitions adds to the completeness of the document • Example: Definition for SDR includes the FCC and ITU-R definitions as well as the preferred IEEE 1900 definition. • Some existing IEEE definitions are quoted; in other cases, a new definition for an existing IEEE term is created with a footnote explaining why an additional definition is required for the dynamic spectrum access context. Informal Briefing to SDR Forum MLM Work Group
Major Sections in the IEEE 1900.1 Standard • Overview • Definitions of Advanced Radio System Concepts (Normative) • Definitions of Radio System Functional Capabilities (Normative) • Definitions of Network Techniques that Support Advanced Radio System Technologies (Normative) • Spectrum Management Definitions (Normative) • Glossary of Auxiliary Terms (Normative) Annex A: Implications of Advanced Radio System Technologies for Spectrum Management (Informative) Annex B: Explanatory Notes on Advanced Radio System Technologies and Advanced Spectrum Management Concepts (Informative) Annex D: List of Acronyms and Abbreviations (Informative) Annex D: Bibliography (informative) Informal Briefing to SDR Forum MLM Work Group
IEEE 1900.2 Working Group on Coexistence Best Practices • Title:Recommended Practice for the Analysis of In-Band and Adjacent Band Interference and Coexistence Between Radio Systems • Scope of the IEEE 1900.2 Standard • This standard will provide technical guidelines for analyzing the potential for coexistence or in contrast interference between radio systems operating in the same frequency band or between different frequency bands. • Purpose of the IEEE 1900.2 • New concepts and technologies are rapidly emerging in the fields of spectrum management, policy defined radio, adaptive radio and software defined radio. A primary goal of these initiatives is to improve spectral efficiency. This standard will provide guidance for the analysis of coexistence and interference between various radio services. • Status: Published 29 July 2008 Informal Briefing to SDR Forum MLM Work Group
IEEE 1900.3 Working Group On Conformance Assurance • Scope: • The scope of this standard is to specify techniques for testing and analysis to be used during compliance and evaluation of radio systems with dynamic spectrum access (DSA) capability. The standard also specifies radio system design features that simplify the evaluation challenge. • Purpose: • While there has been vigorous research on and prototyping of radio systems with dynamic spectrum access (DSA), the potential for deployment may be affected by the ability of regulatory agencies and industry stakeholders to verify that a system conforms to applicable technical and policy requirements. This standard focuses on RF system test to make to feasible to provide such assurance. • Status:Work on this standard has been suspended. Informal Briefing to SDR Forum MLM Work Group
IEEE 1900.4 Working Group on Cognitive Spectrum Management • Title:Architectural Building Blocks Enabling Network-Device Distributed Decision Making for Optimized Radio Resource Usage in Heterogeneous Wireless Access Networks • Scope • The standard defines the building blocks comprising • Network resource managers, • Device resource managers, • The information to be exchanged between the building blocks, for enabling coordinated network-device distributed decision making which will aid in the optimization of radio resource usage, including spectrum access control, in heterogeneous wireless access networks. The standard is limited to the architectural and functional definitions at a first stage. The corresponding protocols definition related to the information exchange will be addressed at a later stage. • Purpose • The purpose is to improve overall composite capacity and quality of service of wireless systems in a multiple Radio Access Technologies (RATs) environment, by defining an appropriate system architecture and protocols which will facilitate the optimization of radio resource usage, in particular, by exploiting information exchanged between network and mobile Terminals, whether or not they support multiple simultaneous links and dynamic spectrum access. • Status:First standard in this series was published FEB 2009; Work has started on subsequent standards in the family. Informal Briefing to SDR Forum MLM Work Group
IEEE P1900.5 Working Group on Policy Architecture and Policy Languages Title: Standard on Policy Language and Policy Architectures for Managing Cognitive Radio for Dynamic Spectrum Access Applications Scope: This standard defines a set of policy languages, and their relation to policy architectures, for managing the functionality and behavior of cognitive radios for dynamic spectrum access applications in a vendor-independent fashion. Purpose: The purpose of this standard is to define a policy language (or a set of policy languages or dialects), and their relation to policy architectures, for specifying interoperable, vendor-independent control of Cognitive Radio functionality and behavior for Dynamic Spectrum Access resources and services. This standard will also define policy language, architecture, and their relation with each other with respect to the needs of at least the following constituencies: the regulator, the operator, and the network equipment manufacturer. Status: Goal is for completion by April 2010 Informal Briefing to SDR Forum MLM Work Group

IEEE P1900.5 Overview • In addition to the SCC41 General Meetings, the IEEE 1900.5 has 2 – 3 F2F meetings a year and 1-2 telecons a month. • Three subgroups identified to focus work: • Policy Architecture Ad Hoc • Policy Language Ad Hoc • Use Case Analysis Ad Hoc • Ad Hoc Groups meet via teleconference approximately twice per month. • There is heavy participation in the ad hoc groups by key people in the SDR Forum Informal Briefing to SDR Forum MLM Work Group
IEEE P1900.5 Status • The Ad Hoc Groups have developed System Engineering Documents (SEDs) on Policy Architecture, Policy Language, and Definitions. • Work is in progress to integrate these SED’s into the initial version of the draft P1900.5 Standard entitled, “IEEE Standard on Policy Architectures and Policy Language for Managing Cognitive Radio Systems and Networks Employing Dynamic Spectrum Access.” • Target completion date: April 2010 Informal Briefing to SDR Forum MLM Work Group
IEEE 1900.6 Working Group on Spectrum Sensing • Scope: • The intended standard defines the information exchange between spectrum sensors and their clients in radiocommunication systems. The logical interface and supporting data structures used for information exchange are defined abstractly without constraining the sensing technology, client design, or data link between sensor and client. • Purpose: • The purpose of this intended standard is to make development and evolution of spectrum sensors independent of the development and evolution of other system functions. To alleviate the limitations of spectrum availability for new technologies evolution of the regulatory regimes is needed. Changes to the regulatory environment will require reliable dependable trusted spectrum sensing capabilities that are fundamental to any advanced radio systems application. Recently proposed advanced radio systems based on sensing technology combine sensing and the protocols and cognitive engines that use the sensing results into proprietary architectures. This model of development reduces innovation and limits the opportunities for integrating new component technologies for better system performance. Further the results of sensing extend beyond the activities of a single system and are ideally integrated into the larger spectrum management process to including the development of spectrum use monitoring and enforcement activities. Many different sensing techniques have been defined so far, there has been no effort to ensure interoperability between sensors and clients provided by different manufacturers. Sensing techniques have been defined without considering their compatibility with other existing solutions. This group develops a standard that defines the interfaces and data structures required for exchange of sensing related information. The resulting standard will provide a formal definition of data structures and interfaces for exchange of sensing related information • Status: Work is continuing at a rapid pace; completion expected by FEB 2010.
