Secondary spectrum allocation framework via concurrent auctions for 5G and beyond networks

Due to the dramatic increase of spectrum demand, efficient usage limited resources has become a crucial issue for next-generation wireless networks. Auction-based trading, utilization and pricing have many promising features proven be fair consistent way secondary trading management. In this paper, we present mathematical approach future market where multiple buyers (secondary network operator) compete gain through number auctions from sellers (primary operator, PNO). Through static dynamic auctions, operators borrow underutilized licensed primary either predefined contracts or instantaneous contracts. Our main focus is on optimal choice contiguous resource maintain quality history based allocation controlled by third party regulators (SR), which not been addressed previously. We first develop matching problem identify most suitable operators. A price-based utility-based ranking bid are proposed, operator maximizes net utility surplus (NUS). The win lose, determined proposed Vickery-type mechanism. Finally, provide simulation results evaluate performance auction
