Wireless services that rely on Dynamic Spectrum Access (DSA) or spectrum sharing mechanisms require a well-defined means to communicate how each device or system is using spectrum resources in a particular environment or situation so that the devices that receive such information can make rational decisions on the possible use of the spectrum. Spectrum consumption models (SCMs) address this issue by providing a means to capture the spectral, spatial, and temporal characteristics of spectrum usage for any specific transmitter, receiver, system, or collection of systems. Since 2012 the 1900.5 working group of the IEEE Dynamic Spectrum Access Networks Standardization Committee (DySPAN-SC) has been working on the IEEE 1900.5.2 standard which defines a data model for SCMs and procedures to arbitrate compatibility among combinations of RF devices and/or systems that have expressed the boundaries of their spectrum use with SCMs. This poster provides an overview of SCMs with a focus on example use cases related to current spectrum management scenarios (i.e. SAS, AWS-3, etc.) to illustrate how SCMs can enable innovative and efficient spectrum use interactions in the near future.
