Considering CoMP for efficient cooperation among heterogeneous small cells in 5G networks

Abstract

The fifth generation of mobile networks is rapidly evolving and novel architectures and communication paradigms are constantly proposed. Heterogeneous wireless networks and particularly dense small cells are a key enabler for increased throughput and high-quality communications, although such densely distributed access networks suffer the effect of inter-cell interference. The coordinated multi-point operation is already considered as a promising technique for mitigating this problem by allowing the coordination of multiple transmission points that serve the user. In this study, the coordinated multi-point is applied in a simulated wireless network in order to measure its performance under varying conditions, including a varying number of static or roaming users, variable required SINR levels and transmission power required to satisfy the requirements. The simulation results indicate that the scheme can achieve significantly low transmission power levels, while serving wireless users at the edge of the cells with SINR of $20dB$, suggesting this technique for future network implementations.
