- Abstract
- Coordinated Multi-Point (CoMP) – Joint Processing (JP) is a technique which improves the cell edge user data rate and spectral efficiency. It is efficiently to overcome the inter cell interference problem through Base Station (BS) cooperation techniques. The practical requirements for CoMP-JP in terms of capacity and latency constraints should be solved by considering backhaul network. The possibility of deploying CoMP-JP in practical cellular systems strongly depends on the backhaul network capabilities. We proposed a selective clustering scheme based on User Equipment (UE) Path which is able to select coordinated BSs dynamically in order to decrease the traffic load of the backhaul network for CoMP-JP. In addition, we proposed a novel frequency allocation scheme for downlink CoMP-JT considering our proposed selective clustering. We are able to decrease intra-cell and inter-cell interference with our proposed frequency reuse scheme considering features of the Orthogonal Frequency Division Multiple Access (OFDMA) systems. Therefore we increase the spectral efficiency and SINR (signal to interference and noise ratio) performance of the system.
