Both data traffic and number of subscriptions have enormously increased inmobile network in recent years. Moreover, there will be an even faster growthin the future. A promising way to satisfy a significantly increasing demand infuture radio access network is by using so called Ultra Dense Networks (UDNs)which deploy a large number of base stations compared to the number of activeusers.Radio spectrum is a finite resource and therefore has to be shared by multipleusers. This sharing of radio spectrum inevitably causes interference betweenthe users. In this study, the interference management performance of differentresource allocation schemes in different network density is studied, which is froma traditional network density to ultra dense network.Except for traditional frequency reuse scheme and reuse partitioning scheme,Coordinated Multi Point (CoMP) schemes have been chosen in the work. Different CoMP techniques such as the universal frequency reuse (UFR) and coop-erative frequency reuse (CFR) are tested to find the best network performancein terms of average users data throughput and cell rate.Besides, after measuring these CoMP schemes which are designed for highbase station density, the optimal scheme is found to be a potential methodadopted by ultra-dense network.
