Fair Dynamic Spectrum Management in Licensed Shared Access Systems
M. Majid Butt, Irene Macaluso, Carlo Galiotto, Nicola Marchetti

TL;DR
This paper introduces a fair and regulation-aware dynamic spectrum management algorithm for Licensed Shared Access systems, ensuring equitable spectrum sharing among mobile operators and addressing compliance issues.
Contribution
It proposes a novel spectrum management algorithm that incorporates regulatory compliance and extends to multi-incumbent scenarios, enhancing fairness and flexibility.
Findings
Spectrum allocation is fair when operators comply with regulations.
Penalty functions influence spectrum sharing when operators misbehave.
Multi-incumbent scenarios reveal a trade-off between efficiency and flexibility.
Abstract
Licensed Shared Access (LSA) is a spectrum sharing mechanism where bandwidth is shared between a primary network, called incumbent, and a secondary mobile network. In this work, we address dynamic spectrum management mechanisms for LSA systems. We propose a fair spectrum management algorithm for distributing incumbent's available spectrum among mobile networks. Then, we adapt the proposed algorithm to take mobile network operator's regulatory compliance aspect into account and penalize the misbehaving network operators in spectrum allocation. We extend our results to the scenario where more than one incumbent offer spectrum to the mobile operators in a service area and propose various protocols, which ensure long term fair spectrum allocation within the individual LSA networks. Finally, we numerically evaluate the performance of the proposed spectrum allocation algorithms and compare…
