The highly directional and adaptive antennas used in mmWave communication open up the possibility of uncoordinated sharing of spectrum licenses between commercial cellular operators. There are several advantages to sharing including a reduction in license costs and an increase in spectrum utilization. In this paper, we establish the theoretical feasibility of spectrum license sharing among mmWave cellular operators. We consider a heterogeneous multi-operator system containing multiple… 
Performance Evaluation of Spectrum Sharing in mmWave Cellular Networks using Ray-Tracing
TLDR
Simulation results for a multi-operator mmwave mobile network show that spectrum sharing outperforms the exclusive license model in terms of capacity for the majority of users, and users with low signal reception do not benefit from the availability of higher bandwidth links and an exclusive license approach consists of a better solution due to the lower interference levels involved.
On the value of Beamforming and Coordination for Spectrum Sharing in mmWave Cellular Networks
TLDR
This paper investigates up to which extent spectrum sharing in mmWave networks with multiple cellular operators is a viable alternative to the traditional dedicated spectrum allocation and develops a general mathematical framework to characterize the performance gain that the users can experience by spectrum sharing as a function of the underlying beamforming, operator coordination, bandwidth, and infrastructure sharing scenarios.
Spectrum Sharing in mmWave Cellular Networks via Cell Association, Coordination, and Beamforming
TLDR
A general mathematical framework is developed to characterize the performance gain that can be obtained when spectrum sharing is used, as a function of the underlying beamforming, operator coordination, bandwidth, and infrastructure sharing scenarios, which can provide important insights for future standardization and spectrum policy.
Gains of Restricted Secondary Licensing in Millimeter Wave Cellular Systems
TLDR
This paper model a mmWave cellular system, where an operator that primarily owns an exclusive-use license of a certain band can sell a restricted secondary license of the same band to another operator that has a restriction on the maximum interference it can cause to the original network.
Restricted Secondary Licensing for mmWave Cellular: How Much Gain Can Be Obtained?
TLDR
This paper model a mmWave cellular system where an operator that primarily owns an exclusive-use license of a certain band can sell a restricted secondary license of the same band to another operator, which has a restriction on the maximum interference it can cause to the original network.
Independence and Fairness Analysis of 5G mmWave Operators Utilizing Spectrum Sharing Approach
TLDR
An analytical framework involving a flexible hybrid mmWave SSA and an adaptive multi-state mmWave cell selection scheme is proposed to associate typical users with the tagged mmWave base stations that provide a great signal-to-interference plus noise ratio, thereby maintaining reliable connections and enriching user experience.
Resource sharing in 5G mmWave cellular networks
TLDR
Key findings of this study include the strong dependence of the comparative results on channel propagation and antenna characteristics, and therefore the need to accurately model them, and the desirability of a full spectrum and infrastructure sharing configuration, which may result in increased user rate as well as in economical advantages for both service provider.
A Model for Infrastructure Sharing in mmWave Cellular Networks
TLDR
An interesting observation is that sharing spectrum and infrastructure yields a higher rate coverage probability for higher rate thresholds, but has a lower coverage for lower thresholds, which suggests that networks catering for low-rate, limited-QoS devices, are at a disadvantage when Spectrum and infrastructure are shared.
Hybrid Spectrum Sharing in mmWave Cellular Networks
TLDR
This paper introduces a new hybrid spectrum access scheme for mmWave networks, where data packets are scheduled through two mmWave carriers with different characteristics, and shows that this approach provides advantages with respect to traditional fully licensed or fully pooled spectrum access schemes.
Modeling Infrastructure Sharing in mmWave Networks With Shared Spectrum Licenses
TLDR
A mathematical framework to model a multi-operator mmWave cellular network with co-located base-stations (BSs) is proposed, which characterize the signal-to-interference-plus-noise ratio distribution for an arbitrary network and derive its coverage probability.

Can operators simply share millimeter wave spectrum licenses?
TLDR
It is shown that shared licenses can use a smaller bandwidth to achieve the same per-user median rate as providers with an exclusive spectrum license, which implies that the optimal amount of spectrum sharing depends on the target rate.
Spectrum-Sharing Transmission Capacity
TLDR
The spectrum-sharing transmission capacity (S-TC) is defined as the number of successful transmissions per unit area subject to outage probability constraints for each system and a fair coexistence constraint is proposed to prevent some systems from monopolizing access to the spectrum.
Spectrum Sharing for Device-to-Device Communication in Cellular Networks
TLDR
A tractable hybrid network model where the positions of mobiles are modeled by random spatial Poisson point process is proposed and derived analytical rate expressions are applied to optimize the two D2D spectrum sharing scenarios under a weighted proportional fair utility function.
Licensed shared access for wave cellular broadband communications
TLDR
Licensed Shared Access (LSA) Spectrum Sharing technology is proposed to be used as a key enabler in such cases, i.e. for managing Quality of Service (QoS) guaranteed access for future 5G cellular systems, where incumbents are maintain priority access rights to mmWave spectrum.

TLDR
It is shown that coverage in mmWave systems can rival or even exceed coverage in microwave systems assuming that the link budgets promised by existing mmWave system designs are in fact achieved and this comparable coverage translates into a superior average rate performance for mmWave Systems as a result of the larger bandwidth available for transmission.
Infrastructure and spectrum sharing trade-offs in mobile networks
TLDR
The fundamental trade-offs between spectrum and radio access infrastructure sharing are assessed, and it is shown that a larger operator has more to gain from sharing due to disproportionally lower interference suffered from the smaller operator.
Millimeter Wave Channel Modeling and Cellular Capacity Evaluation
TLDR
Detailed spatial statistical models of the channels are derived and it is found that, even in highly non-line-of-sight environments, strong signals can be detected 100-200 m from potential cell sites, potentially with multiple clusters to support spatial multiplexing.
