Abstract
A technique () and apparatus for sharing frequency spectrum amongst cognitive radios is provided. By maintaining an unoccupied spectral quantum between each CR device, the channel technique ensures that a device just beginning transmissions in the CR frequency band will have spectrum from which to start growing. The growth can continue up to the maximum the spectrum can support, when the bandwidth of each device has been reduced to one spectral quantum, and there are no available spectral quanta left.
