Performance Analysis of Cross Component Carrier Scheduling in LTE Small Cell Access Point System

With respect to the carrier aggregation (CA) in a LTE small cell access point system, the performance of an independent and cross component carrier (CC) scheduling is simulated and analyzed in this paper. According to the results, we obtained a capacity increase of about 17~46% for the cross CC max rate (MR) algorithm and about 12~45% for the cross CC proportional fair (PF) algorithm. On the other hand, in the round robin (RR) scenario, we cannot notice the differences between the independent CC and cross CC scheduling policies on allocating resources. We also found that CA frequency combination 1.8GHz CC + 800MHz CC has a better performance when comparing to the other combinations with respect to total average UE throughput.
