Advances in Wireless Communications: Spectrum Sharing Techniques for beyond 5G Wireless Networks
In recent decades, wireless communication theory has made remarkable progress with developments such as multiple-input multiple-output (MIMO), multi-user MIMO, massive MIMO, and spectrum-sharing techniques like cognitive radio, full-duplex radio, non-orthogonal multiple access (NOMA), and integrated sensing and communication (ISAC). This course offers a comprehensive overview of wireless communication fundamentals and recent innovations, focusing on spectrum-sharing techniques for Beyond 5G Wireless Networks.
Dynamic spectrum sharing is increasingly crucial in Beyond 5G technologies, and this course explores the technical and regulatory advancements underpinning this evolution. Key trends, such as licensed shared access and its role in ensuring the quality of service for users, are discussed in a manner accessible to participants with a foundational understanding of signal processing, MIMO communications, and cognitive radio networks.
The course aims to:
- Introduce the fundamentals of spectrum-sharing technologies over the last two decades, including sensing-based cognitive radios and licensed/authorized shared access.
- Provide insights into regulatory milestones, standardization efforts, and global frameworks from organizations like the FCC and Ofcom.
- Cover topics such as licensed shared access, network architecture, and the emergence of secondary spectrum markets that impact the economics of the wireless industry.
- Participants will also delve into cutting-edge research, future challenges, and economic implications, making this course indispensable for professionals and researchers working in 5G and Beyond 5G domains.

Licensed shared access, Spectrum Sharing economics, Valuation, and Secondary Markets, Future outlook of spectrum sharing
Licensed (/authorized) shared access is one of the most recent trends of
spectrum sharing and constitutes an important milestone, in that it provides
certain guarantees of quality of service to the users of both incumbent and
licensee operators. Basics of the licensed / authorized shared access approach
and will discuss the key network architectural elements required to support this
type of spectrum sharing.
The emergence of robust markets for spectrum sharing will change the
economics of wireless with both predictable, and uncertain implications for how
spectrum is valued. This lecture will explore how the emergence of secondary
spectrum sharing markets will impact wireless industry economics and the
valuation of spectrum resources.
This lecture will provide a number of conclusions and forecasts regarding the
evolution of today’s spectrum sharing landscape. The provided outlook will
focus mostly on commercially available systems and their anticipated
evolution, taking into account the current regulatory and standardization
trends.
