摘 要：This work studies the revenue-maximizing auction of a single block of spectrum that can be awarded either for exclusive licensed use by one operator or reserved for unlicensed use. A number of operators bid for exclusive licensed use and a group of non-colluding agents bid to keep the spectrum unlicensed. The revenue of this auction is compared to that of a Vickrey-Clarke-Groves (VCG) auction and that of another auction recently proposed.
