Flexible Spectrum Use for IMT-Advanced: WINNER+ Spectrum Concept

Ever increasing demands for higher data rates of mobile communication systems and the fact that many parts of the frequency spectrum are already occupied but often underutilized have led, in recent years, to increased focus on flexible spectrum use and dynamic spectrum sharing concepts. In this paper, the authors provide an overview of the WINNER+ activities that are related to flexible spectrum use and its application in IMT-Advanced systems. The considered activities include: preferred spectrum use in WINNER+, the digital dividend, femto-cells deployment, self-organization using TDD underlay concept, uncoordinated deployments and intra- and inter-RAN spectrum sharing.
