IEEE P1900.6

Working Group on Spectrum Sensing Interfaces and Data Structures for Dynamic Spectrum Access and other Advanced Radio Communication Systems

Scope and objectives

The IEEE Std 1900.6™-2011was published on April 22nd 2011. The standard can be obtained at: http://standards.ieee.org/findstds/standard/1900.6-2011.html.

 From June 2011, the 1900.6 Working Group works on a new project:

1900.6a: Standard for Spectrum Sensing Interfaces and Data Structures for Dynamic Spectrum Access and other Advanced Radio Communication Systems Amendment: Procedures, Protocols and Data Archive Enhanced Interfaces. (PAR)

  • Scope: This Amendment to the IEEE Std 1900.6TM adds procedures, protocols and message format specifications for the exchange of sensing related data, control data and configuration data between spectrum sensors and their clients. In addition, it adds specifications for the exchange of sensing related and other relevant data and specifies related interfaces between the data archive and other data sources.
  • Purpose: This amendment provides specifications to allow integrating 1900.6 based distributed sensing systems into existing and future dynamic spectrum access radio communication systems. It enables existing legacy systems to benefit so as to widen the potential adoption of the IEEE 1900.6 interface as an add-on to these systems and to claim standard conformance for an implementation of the interface. In addition it facilitates sharing of spectrum sensing data and other relevant data among 1900.6 based entities and external data archives.  

Technical relevance to QoSMOS

This standard defines the information exchange between spectrum sensors and their clients in radio communication systems. The logical interfaces and supporting data structures used for information exchange between the various entities in advanced radio systems have been  defined as abstract interfaces without constraining the actual sensing technology, client design, or data link between sensor and client. The IEEE 1900.6-2011TM Standard was approved in January 2011 and has been published on April 22nd 2011. A new Project Authorisation Request has been granted by the IEEE standards board, in May 2011, and work on this proposed amendment to  IEEE 1900.6-2011TM has started on June 20th 2011. The new project is expected to be completed in autumn 2012 and the amendment published in early 2013.

Work in 1900.6 is of high relevance for QoSMOS as it addresses functions and interfaces that are relevant for the QoSMOS system architecture. Till autumn 2011 this working work was chaired by a member of QoSMOS. 

Status and outlook for QoSMOS

The working group identified 6 working items that closely matched the objectives of QoSMOS.

  1. Utilization of legacy sensors in 1900.6 distributed sensing systems (based on a QoSMOS proposal);
  2. Use cases for sensing Green Cognitive Radio (e.g. sensing and classification of opportunistic energy-aware spectrum users);
  3. Spectrum sensing protocols (e.g. message flow details);
  4. Generation of (and use cases for) spectrum maps from sensing results, in particular for large areas and for indoor areas;
  5. Identification of (and use cases for) potential data sources to an enhanced data archive along with suitable protocol and data structures for communication between external data source and data archive;
  6. Proposals for mapping the 1900.6 Communication Service Access Point to (heterogeneous) realizations of a communication subsystem (e.g. transport / network layer services).

Determining spectrum maps, considering indoor scenarios and interaction between spectrum sensing, database and white space device as well as protocols and procedures to realize distributed spectrum sensing with heterogeneous legacy implementations of spectrum sensors are focus topics of multiple QoSMOS WPs. QoSMOS submissions to 1900.6a had a significant impact on the scope and output of this project especially as they were  provided during the phase of establishing the work plan.

The first draft 1900.6a has been finalized in May 2013 and is now entering sponsor ballot.
