ABSTRACT
We provide a method to specify location based
spectrum rights that enables spectrum management with finer
resolution in space and frequency. This method accounts for the
attenuation of transmissions from their source and so reveals the
location based opportunities to reuse spectrum. The method uses
a concise yet flexible data structure that has six parts: a signal
strength, a frequency, a spectrum mask, a power map, a
propagation map, and a scaling factor. Through the use of one
or multiple of these parts most any type of spatial spectrum use
authorization or protection may be defined. The structure allows
spectrum to be managed as a spatial resource and so subdivided
for spatial reuse or for resale. We provide several examples to
demonstrate its versatility in spectrum management. We provide
some observations and theorems that are useful in developing
algorithms to verify compliance to the rights and restrictions
conveyed in the proposed method and to discern when coexistent
spectrum use is possible. This method provides a unified
approach to define spectrum use that can be used to license
spectrum, to optimize spectrum reuse, to negotiate spectrum
rights, and to specify spectrum policy. It is ideally suited for
over-the-air management of spectrum use.
