User-Centric Strategy for Base-StationVirtualization in 5G Networks

Abstract

This paper proposes a new user-centric base-station(BS) virtualization strategy aiming to adapt users communica-tion links to their quality of service (QoS) requirements andenvironments. The developed user-centric virtual base stations(uVBS)s offer substantial improvements in terms of power andspectral efficiencies while requiring minimum signaling changesat both user and network sides. They also better leverage new 5Gfeatures such as massive connectivity and extreme densificationas well as new concepts such as massive MIMO and mmWavespectrum. Furthermore, our uVBSs are able to adapt to multiplenetwork dimensions such as time, space, etc
