Control Framework for Ultra-dense cellular networks

The current work focuses on the current network deployments and the transition to the 5G era, toward encompassing the proposed approaches in the network design. In this direction, the base station densification gain and the control/coordination of the Radio Access Network (RAN) are being taken into account. The densification gain (with respect to the Base Station density) represents the ability of the network to offer the desired data rate and comply with other important key performance indices for a 5G environment. Finally, load balancing and offloading techniques are discussed which are going to play an important role in the future networks. A coordination framework for the whole RAN infrastructure has been described by setting the criteria and the control mechanisms for the management of the network.
