Abstract :
Mobile broadband data usages in LTE-A networks are growing exponentially leading to more relay node (RN) installations to improve network performance and spatial efficiency. In heterogeneous networks, however, the signals transmitted by improperly deployed RNs can aggravate the interference problem. Therefore, it is paramount to properly position RNs to mitigate the signal interference. In this paper, we propose an algorithm that installs RNs in a cost-efficient and throughput effective manner.
