The authors propose to use generalization of a second price VCG auction to dynamically allocate shared radio resources among collocated, equally prioritized mobile network operators in multi carrier HSDPA cellular network. The spectrum usage priority will be dynamically decided based on the comparison of individual valuation functions, used as an input for the spectrum auctioning game. After theoretical introduction to the game theory, they demonstrate that short term auction based spectrum sharing provides spectrum utilization gains for coalition of MNO's having un-equal cell specific traffic loads, allowing network operators to secure their business and at the same time, open new market possibilities with additional revenue opportunities.
