A Spectrum Sharing Solution for the Efficient Use of mmWave Bands in 5G Cellular Scenarios
Regulators all around the world have started identifying the portions of the
spectrum that will be used for the next generation of cellular networks. A band
in the mmWave spectrum will be exploited to increase the available capacity. In
response to the very high expected traffic demand, a sharing mechanism may make
it possible to use the spectrum more efficiently. In this work, moving within
the European and Italian regulatory conditions, we propose the use of Licensed
Spectrum Access (LSA) to coordinate sharing among cellular operators.
Additionally, we show some preliminary results on our research activities which
are focused on a dynamic spectrum sharing approach applied in simulated 5G
cellular scenarios.Comment: to be published in IEEE International Symposium on Dynamic Spectrum

Postgraduate Studies).The authors would like to thank the following members of Ericsson and Nokia
Company for their valuable technological support in relation to the deployment of 5G networks in
Colombia and Latin America. To Ericsson Company: Fabian Monge, Head of Networks & Managed

Director & Business Development Colombia—Nokia.The deployment of the 5G mobile network is currently booming, offering commercially
available services that improve network performance metrics by minimizing network latency in
countries such as the USA, China, and Korea. However, many countries around the world are still in
the pilot phase promoted and regulated by government agencies. This is the case in Colombia, where
the assignment of the first 5G band is planned for the third quarter of 2021. By analyzing the results
of the pilot phase and the roadmap of the Colombian Ministry of Information and Communication
Technologies (MinTIC), we can determine the main issues, which contribute to the deployment of
5G mobile technology as well as the plans to achieve a 5G stand-alone network from 4G networks.
This is applicable to other countries in Latin America and the world. Then, our objective is to
synthesize and share the most important concepts of 5G mobile technology such as the MIMO
(multiple input/multiple output) antenna, RAN (Radio Access Network), C-RAN (Centralised-RAN),
and frequency bands, and evaluate the current stage of its introduction in Colombia.AUIP (Iberoamerican University Association for

A Game-Theoretic Framework to Regulate Freeriding in Inter-Provider Spectrum Sharing
Primary-secondary spectrum sharing is limited in terms of design space, and may not be sufficient to meet the ever-increasing demand of connectivity and high signal quality. The next step to increase spectrum sharing efficiency is to design markets where sharing takes place among primary providers rather than leaving it to the limited case where the primary licensee is idle. Attaining contractual spectrum sharing among primary providers, a.k.a. co-primary or inter-provider sharing, involves additional costs for the users, e.g., roaming fee. Co-primary spectrum sharing without additional charge to the users poses two major challenges: a) regulatory approaches must be introduced to incentivize providers to share spectrum resources, and b) small providers in co-primary spectrum sharing markets may freeride on large providers’ networks as the customers of the small providers may be using the spectrum and infrastructure resources of large providers. Such freeriding opportunities must be minimized to realize the benefits of primary-level sharing. We consider a subsidy-based spectrum sharing (SBSS) market to facilitate co-primary spectrum sharing where providers are explicitly incentivized to share spectrum resources. We focus on minimizing freeriding in SBSS markets and introduce a game-theoretic model to regulate the freeriding. We use the model to explore operational regimes with minimal freeriding
