The Radio Frequency (RF) spectrum is the key resource that enables the use and growth of wireless services. Modern approaches for RF spectrum management focus on moving away from rigid management policies and instead are embracing dynamic spectrum access (DSA) and spectrum sharing mechanisms. The implementation of DSA and spectrum sharing mechanisms require an effective means of communicating the characteristics and limits of the spectrum use and interference tolerance limits of an RF transmitter, receiver, system, or collection of systems. Spectrum consumption models (SCMs) as defined by the IEEE 1900.5.2 standard, provide an information model to capture the spectral, spatial, and temporal characteristics, and boundaries of the use of spectrum by any specific transmitter or receiver device or RF system. Additionally, the standard defines the criteria to arbitrate compatibility among combinations of RF devices and/or systems that have expressed the boundaries of their spectrum use with SCMs.
The information contained in SCMs enables new RF spectrum management practices and allows for the identification of spectrum reuse opportunities. SCMs enable the creation of algorithms to optimize the use of spectrum across multiple users. This talk presents and discusses current efforts and results in the design of large-scale spectrum use deconfliction and sharing mechanisms with SCMs and the design of a spectrum use coordination system for a Radio Dynamic Zone (RDZ) with the use of SCMs. Future perspectives on the use of SCMs for conveying spectrum use policy to radio systems and for the development of distributed spectrum management techniques will also be covered.
