Network densification is widely accepted as one of the solutions that will allow to meet the 1000x capacity challenge in future generation networks. Small cell networks (SCN) allow higher spatial reuse and so higher area spectral efficiency. However, mobility issues appear and handover robustness deteriorates for users at moderate speed, which translates into connection dropping and throughput degradation. In order to overcome these problems, this paper proposes a new scheme based on cooperative multi-point (CoMP) combined with dual connectivity with control and user plane splitting. Results show a decrease in frequent handover failures and the corresponding throughput ga ins. Thus the integration of these users into the SCN would be a feasible option.
