As we evolve towards 5G networks, achieving spectral efficiency and energy efficiency and dealing with interference are among the greatest challenges encountered so far. The paper looks at interference issues and its causes in Heterogeneous Cellular Networks (HetNets) and how they have been combated using different management techniques. It is found that most of these interference management techniques, when applied to HetNets, do improve the performance of HetNets, but could not mitigate dominant interference scenarios in HetNets when frequency reuse-one deployment is employed. Solutions are proffered to these dominant interference scenarios in HetNet.
