Selective clustering scheme based on user equipment path and frequency reuse scheme for coordinated multi-point joint processing

Abstract

Coordinated multi-point (CoMP) - joint processing (JP) is a technique which improves the cell edge user data rate and spectral efficiency. 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. The authors propose a selective clustering scheme which is able to selectively form clusters in order to decrease the traffic load of the backhaul network for CoMP-JP. In addition, the authors propose a new frequency reuse scheme for downlink CoMP-JP. The authors are able to decrease intra-cell and inter-cell interference with our proposed frequency reuse scheme. Therefore the authors increase the spectral efficiency and SINR (signal to interference and noise ratio) performance of the system.
