Abstract

Femtocells have been proposed for improving the performance of indoor users to provide better indoor coverage and spatial reuse gains in the 4G networks. On the one hand, users enjoy high-quality links; on the other hand, operators decrease the operational expenditure (OPEX) and capital expenditure (CAPEX) due to the traffic offloading and user’s self-deployment of femtocell base stations (FBSs). As femtocells can meet users’ demand and indoor coverage requirement well, they have been widely used in many wireless communication standards, such as WiMAX, and LTE/LTE-Advanced. However, there are still some challenges in the mass deployed femtocell environment. Interference management is considered as one of the major challenges in femto-macro two-tier networks. In this chapter, we survey different state-of-the-art approaches of resource allocation and interference management in orthogonal frequency division multiple access (OFDMA) femtocell networks. Moreover, some open challenges in interference and resource management are discussed.
