Average UE throughput and CRE throughput for different biasing approaches. NC and C refers to no CoMP and CoMP, respectively. In this figure, the average user throughput and the throughput of cell range expansion for biased user association with and without CoMP are shown. From the figure, per base station biasing using particle swarm optimisation outperforms the per-tier biasing with and with no CoMP
