-This paper proposes a new system architecture for Licensed Shared Access (LSA) wireless networks, as well as novel band management techniques for fair and ranking-based spectrum allocation. The proposed architecture builds upon recently standardized and regulatory-accepted LSA systems and stems from the work done in the EU-funded project ADEL. Two new resource allocation algorithms are introduced and their behavior is validated via system-level simulations.

Future generation of cellular mobile networks are requested to connect an increased number of devices with different connectivity requirements. While some of these devices have no capability to perform advanced signal processing algorithms, others will. This opens the possibility to use non-orthogonal multiple access (NOMA) schemes in future radio access networks. In these schemes the users are multiplexed in power domain in the transmitter and de-multiplexed using successive interference cancellation in the receiver. In this work we propose hybrid resource allocation of orthogonal and non-orthogonal radio resources and determine the improvements on cell capacity achieved in single cell millimeter wave scenarios.

Cognitive Radio Communications and the switch off of analog TV in Europe is creating a strong and viable solution for testing new approaches to the implementation of Cognitive Radios in an effective way. In this paper the concept of White Spaces and specially the approaches that are thought to be developed in Europe will be studied and analyzed. It is expected that this work will be the basis for more focus on the white space communication protocols.
