Interference Mitigation Approach towards 5 G network

In the recent years, the demand for higher data rates has been continuously growing to satisfy consumers’ desire for a faster, safer, and smarter wireless network. Since current wireless systems are facing a bottleneck in spectrum resources which make it difficult to enhance performance in the limited available bandwidth. To overcome this problem new Generation of mobile communication known as fifth generation (5G) comes into the picture. The goals of 5G network design are to achieve not only large network capacity, but also ultra-low latency and heterogeneous device support. 5G adopt multi-tier architecture where several low-power Base Stations (BSs) inside small cell are deployed within the coverage area of the macrocell. However, interference by the simultaneous usage of the same spectrum in these cells creates severe problems which reduce system throughput and network capacity. Hence, the resource management is an integral part of 5G HetNets so that interference between different devices can be minimized. The main aim of this work is comprehensive study about the different Interference mitigation approaches in 5G network.
