“…The amount of spectrum allocated to an MNO is the main utility for the licensee operators. If they commit any of the above mentioned violations of LSA spectrum use regulations, it is sufficient to penalize them in future spectrum assignment 1 .

Abstract-We propose a novel Licensed Shared Access (LSA) spectrum allocation framework in this paper. The spectrum is made available to the licensee mobile network operators (MNOs) at specific time instants, in a specific service area, and for a specific time period. We propose a spectrum allocation algorithm which aims at providing resources to the MNOs in such a way that they can utilize them to serve their users and the resource allocation is fair at the same time. We also introduce a penalty mechanism whose output is a reduced spectrum allocation for the MNOs which violate the LSA spectrum use regulations. Our proposed algorithms are evaluated numerically and our results show that we can both guarantee fairness in spectrum allocation and penalize the MNOs that misbehave in regards to the LSA spectrum usage limitations imposed by the incumbent.

“…The dramatically increasing capacity of wireless network is expected to be reached in particular by three key directions: (1) additional spectrum resources, (2) base station densification and (3) increase spectral efficiency [2]. For example, on the basis of (2), currently femtocell solutions such as the AT&T 3G MicroCell, Sprint AIRAVE and Verizon Wireless Network Extender are providing their users better inbuilding coverage.…”

“…Therefore, considering the interests of business and spectrum allocation efficiency, a licensed spectrum sharing among multiple carriers is a potential solution. However, two factors complicate efforts to solve the spectrum sharing problems: (1) Carriers serve their respective users in separated licensed band, but during a certain period of time it is possible that one carrier's femtocell is suffering overloaded, while another carrier's femtocell is still in free status; (2) Unlike macrocells that rely heavily on Global Positioning System (GPS) timing and location, femtocells are typically deployed indoor environments where GPS is less reliable. So the carrier has little knowledge about the placement of the femtocell within the user's home.…”

Femto base stations will be widely deployed in 5G times for compensating poor cellular coverage for use in residential or small business environments. In this paper, we propose a spectrum sharing framework, where a cluster of femtocells are under the control of a centralized local manager. The framework assumes that each femto base station has the sniffing ability that can detect its neighbor femtocells and the controller can then have complete knowledge of local interference constraints. Unlike distributed WiFi that runs on unlicensed band, the femtocell owned by a carrier runs on licensed band and the carrier prefers a centralized system to a distributed one. Therefore, a fair spectrum sharing policy on the licensed band is more important among carriers to break the monopoly and inefficient spectrum allocation. Considering the spectrum can be spatial reused, an interference graph is adopted to avoid the interference between femtocells of all the carriers. We test the framework not only by comparing the average number of channels per user can get but also the variance to guarantee the fairness. In this framework, the scheme combining topological sort and maximum traffic load of femtocell contributes to keep a better balance on the average number of channels and variance.

-This paper proposes a new system architecture for Licensed Shared Access (LSA) wireless networks, as well as novel band management techniques for fair and ranking-based spectrum allocation. The proposed architecture builds upon recently standardized and regulatory-accepted LSA systems and stems from the work done in the EU-funded project ADEL. Two new resource allocation algorithms are introduced and their behavior is validated via system-level simulations.
