Abstract
The capacity and the coverage of any wireless network can be improved in terms of efficiency by moving the transmitter and the receiver closer together. Therefore, the concept of small cells overlapping with traditional macrocells is gaining considerable research attention. However, the mass deployment of HetNets introduces certain challenges that must be addressed to ensure that the expected benefits of the deployment are realized. Among these challenges, interference management is one of the most important when considering co-channel HetNet deployment, where the small cells and the macrocells share the same frequency spectrum. Different approaches can be adopted, depending on several aspects. These include the specific network scenario, the computational capacity of the devices used, the backhaul link and various other factors. This chapter describes the main concepts of interference management in HetNets when they are deployed using a spectrum sharing approach. It also provides an overview of the best known interference management approaches.
