Multi-Block Ascending Auctions for Effective 5G Licensed Shared Access

Abstract

Licensed Shared Access (LSA) is a new concept proposed by the radio spectrum policy group in order to optimize spectrum usage: a Mobile Network Operator (MNO) can access temporarily to other incumbent's spectrum after obtaining a license. The licensing process is made via an auction mechanism. The mechanisms proposed in the literature for the LSA context are oneshot auction mechanisms which allocate all the available spectrum as a unique block. In this paper, we first show how to increase the performance of those auctions (in terms of revenue, efficiency and fairness of the allocation) while preserving truthful bidding, by splitting spectrum and converting single block auctions into multi-block auctions. Simulation results illustrate how appropriately choosing the number of blocks allows to increase the aforementioned metrics. Second, we show how to convert one-shot mechanisms to equivalent ascending mechanisms (in terms of allocations and payments) so that we add transparency and privacy to the auction.

A Truthful Reverse Auction Mechanism for Federated Learning Utility Maximization Resource Allocation in Edge–Cloud Collaboration

“…The resource capacity of each edge server is 5. bw 2 = (0, 2, 1), which means that the transmission rate between user 2 and edge server 2 is 2 M/s (bw 22 = 2), the transmission rate between user 2 and edge server 3 is 1 M/s (bw 23 = 1), and the transmission rate of 0 indicates that the distance between user 2 and edge server 1 is too far to transmit (bw 21 = 0). [5,5,5].…”

“…Previously, auction mechanisms have been widely applied in spectrum auctions [4,5], offline and online cloud computing virtual resource auctions [6][7][8], network flow models [9], edge computing [10] and mobile blockchains [11,12], and their application in FL is feasible [13,14].…”
