Abstract Heterogeneous networks with dense deployment of femto cells has provided the promising solution to enhance the system throughputs for the next generation wireless communication. When the large number of heterogeneous networks are overlapped, then traditional intercell interface technique failed to mitigate the interference in between the cells. So, to mitigate the interference, it requires advanced approach for improving the cell edge throughputs and spectral efficiency. For this, the paper presents a frame work to allocate the efficient resource among the users in dense networks. We proposed affinity propagation unsupervised learning to form the cluster with center and then regularized the cluster for effectively allocated the resource. Users on the cluster edge has suffering the inter cluster interface, a victim aware and coordination multipoint mechanism is further proposed to allocated the required resources for these victimized users. We analyzed the performance of our proposed framework with proportional fair based criteria. The total throughputs, edge throughput and spectral efficiency of the system are significantly enhanced in our simulation results through this proposed framework.

1 Introduction Implementation of Ultra-small cell heterogeneous networks are the key to provide high bandwidth for next generation mobile communication system. Higher data rate and flawless communication in wireless system have always been demanded by Z generation users. Femto cell, Pico cell and Radio Remote Head are most common types of small cell which fulfill the requirements of hungry users [1, 2]. Unlike macro base stations, these can’t be installed by the used of planning tools, small cells are mostly deployed in an unplanned * Amandeep Noliya [email protected] Sanjeev Kumar [email protected] 1

way [3]. Femto cell is the frequently used small base station for small coverage area. It is capability of plug and play where a subscriber can deploy it to receive service without intervention of the operator. Femto cell is also called HeNodeB (Home Base Station) and it has radius range between 10 m to 50 m which is much smaller than the macro cell radius 300 m to 2000 m. It can be organized in a large number in the networks, for achieving a high frequency reuse rate [4]. However, dense deployment of small cell increases heterogeneity in networks that will create the interference (co-channel/cross channel) issues on nearby cell and users served by the macro cell or neighboring femtocell wi
