Cooperative Caching in Dynamic Shared Spectrum Networks
IEEE Transactions on Wireless Communications, 2016This paper considers co-operation between primary and secondary users in shared spectrum radio networks via caching. We first consider a network with one channel shared between a single macro (primary) base station and multiple micro (secondary) base stations.

Decolonizing Dynamic Spectrum Sharing
Spectrum sharing, including dynamic spectrum sharing, is arguably the most significant overarching feature of the new era of spectrum management. The emphasis on sharing spectrum recognizes the importance of balancing the needs of different users of an exceptionally valuable resource.Darrah Blackwater +2 more

Characterization of the missed spectrum-access opportunities under dynamic spectrum sharing
2016 8th International Conference on Communication Systems and Networks (COMSNETS), 2016The radio frequency (RF) spectrum has been observed to be underutilized in the space, time, and frequency dimensions. To improve its utilization and meet growing demand, dynamic spectrum-sharing models are being investigated. In order to maximize the use of spectrum, we study how much of the spectrum can be potentially shared and how much is actually ...

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 sharing for two-layer cellular networks
2011 IEEE 22nd International Symposium on Personal, Indoor and Mobile Radio Communications, 2011Deploying femtocells faces a major challenge of causing downlink interference to the existing macrocell. This paper proposes an intelligent spectrum sharing mechanism for a two-layer cellular network, which comprises macrocells and femtocells. Because users are scheduled to access the spectrum in time-domain according to their channel conditions, the ...

Dynamic Spectrum Access: Implications of the diffusion of spectrum sharing technology.
2012Like 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 ...
