We propose a low-overhead interference-aware approach to spectrally efficient, fully distributed dynamic resource allocation with beamforming support for unassisted broadcast and unicast device-to-device communications. A resource may only be allocated for transmission over a link if a) the transmitter is guaranteed to not cause excessive interference at any scheduled receivers, and b) the total interference...
Ultra dense small cell deployments will play a critical role in addressing future capacity requirements in dense urban outdoor and indoor environments such as train stations and shopping malls. Effective interference and energy management schemes will be needed to make such deployments technically and economically viable. In this paper, we demonstrate the benefits of a database-aided energy savings...
This paper studies potential energy savings that can be realized in dual connectivity heterogeneous networks (HetNets) with densely deployed small cells. Using the Phantom Cell Concept (PCC) as a reference architecture, a novel database-aided mechanism is introduced to provide macro cell-controlled sleep mode functionality to small cells. System level simulations show that a system with this capability...
A next generation Beyond 4G (B4G) radio access technology is expected to become available around 2020 in order to cope with the exponential increase of mobile data traffic. In this paper, research motivations and high level requirements for a B4G local area concept are discussed. Our suggestions on the design of the B4G system as well as on the choice of its key technology components are also presented.
