Hybrid spectrum sharing in dynamic spectrum access networks
In this work, inefficient spectrum usage problem which will lead to spectrum scarcity in future communications has been addressed. According to Federal Communications Commission, spectrum sharing is a technique to efficiently utilize the spectrum. We analyse dynamic spectrum access concepts such as overlay spectrum sharing and underlay spectrum sharing.

Evolution Towards Dynamic Spectrum Sharing in Mobile Communications
2006 IEEE 17th International Symposium on Personal, Indoor and Mobile Radio Communications, 2006This paper provides a broad overview of a number of approaches to dynamic spectrum sharing, and presents a specific case study involving hierarchical co-channel macro- and pico-cells. This case study demonstrates the feasibility of implementing a private commons approach to spectrum sharing in a near term, commercial application. Finally, a roadmap for

Dynamic Spectrum Access: Implications of the diffusion of spectrum sharing technology. [PDF]
Like most common natural resources, spectrum is finite and prone to overuse and "crowding". Most of today's radio systems are not aware of the spectrum environment and operate in a pre-given, static frequency band. Technologies such as cognitive radio (CR) that enable dynamic spectrum access (DSA) have been proposed to improve efficiency and ...

Advanced Dynamic Channel Access Strategy in Spectrum Sharing 5G Systems
5G wireless communications aim at providing higher data rates, spectral efficiency, and energy efficiency than 4G. To achieve this target, the spectrum resource with low utilization is emptied out for 5G refarming.

A Dynamic Spectrum Footprint Adaptation Framework for Collaborative Spectrum Sharing
NOMS 2020 - 2020 IEEE/IFIP Network Operations and Management Symposium, 2020Spectrum sharing is a reality closer than one might think. Dynamic and intelligent spectrum allocation, where different networks collaborate to optimize spectrum usage jointly, is required to overcome spectrum scarcity. Artificial Intelligence (AI) can play a major role to solve this complex problem in dynamic environments with continuously changing ...

Information Sharing in Spectrum Auction for Dynamic Spectrum Access
GLOBECOM 2009 - 2009 IEEE Global Telecommunications Conference, 2009Spectrum under-utilization is one of the bottlenecks of the development of wireless communication, and Dynamic Spectrum Access (DSA) is envisioned as a novel mechanism to solve the problem of spectrum scarcity. Spectrum Auction has been recognized as an effective way to achieve DSA, wherein the primary spectrum owner (PO) acts as an auctioneer who has ...

Dynamic Spectrum Sharing Detectors
2007 2nd IEEE International Symposium on New Frontiers in Dynamic Spectrum Access Networks, 2007Dynamic frequency sharing provides a mean to more efficiently allocate frequency spectrum. For this to be accomplished the ambient spectrum has to be sensed and characterized. This paper presents how energy detection can be used to differentiate signals from noise for various operating environments.

Incentivizing spectrum sensing in database-driven dynamic spectrum sharing
IEEE INFOCOM 2016 - The 35th Annual IEEE International Conference on Computer Communications, 2016The legacy concept of exclusion zones (EZs) is inept at enabling efficient utilization of fallow spectrum by secondary users (SUs), since legacy EZs are static and overly-conservative. The notion of a static EZ implies that it has to protect incumbent users (IUs) from the union of likely interference scenarios, leading to a worst-case, conservative ...

On sellers' quantity games for dynamic spectrum sharing
2013 9th International Wireless Communications and Mobile Computing Conference (IWCMC), 2013The concept of cognitive radio (CR) technology is emerging as a new paradigm for designing next generation wireless networks with dynamic spectrum sharing. Game theory is one of key mathematical tools to model and analyze the spectrum sharing process.
