Inter-Operator Spectrum Sharing for Cellular Networks Using Game Theory

Spectrum sharing and DSA techniques have been active research topics for the past decade due to the spectrum crowd situation. The existing spectrum allocation process, denoted as FSA, headed for static long-term exclusive rights of spectrum usage and shown to be inflexible. In the cellular context two main axis of resource management exist. The JRRM (Joint Radio Resource Management) axe, in which one operator manages jointly his networks (or Radio Access Technology) making benefit of his own licensed bands. The second axe, which the authors call operator sharing DSA (or Inter-operator DSA), in which the competition and/or the cooperation aspects between different operators are explored.
