Femto-BSs, also known as home evolved NodeB (HeNB), are low-power and small scale BSs that are deployed within traditional macro-cellular networks. With these so-called small cells, the spatial reuse of radio resources is tremendously boosted, wall penetration losses are largely mitigated, and users can enjoy high data rates. In addition to its various advantages, the deployment of femtocells also comes with some problems and one of the main issues is the increase in interference.
The interference mitigation in femtocell networks is the main aim of this thesis. In order to achieve this goal, the characteristics and interference environment of femtocell deployments have been investigated, and the properties of interference mitigation techniques applicable to such networks are studied. To this end, dynamic central and distributed resource assignment methods have been developed where network can
update itself depending on the changes in the interference environment. Furthermore, the application of the developed techniques in real network deployments such as Long-Term Evolution (LTE) and Long-Term Evolution-Advanced (LTE-A) have been studied. Although the focus is on femtocell networks, the developed methods in this thesis can be applied to any wireless networks with minor changes.
