Due the rapid increase in mobile and machine type data traffic the densities of networks are growing fast and deployment of local Ultra Dense Networks (UDNs) is seen as a viable solution in 5G framework. In this project we will consider the fundamental 5G challenges including 1) development of connectivity and control structures for high carrier frequency systems, 2) design of new low-latency, lowenergy 5G radio interface, 3) design of novel cooperative communication, beamforming and massive MIMO principles, 4) development of resource allocation principles for layered UDN deployment and 5) design principles enabling energy efficient UDN. We study these topics especially from indoor connectivity and machine type communication perspectives.
