Throughput Performance of Adaptive Control CRE in Multicarrier HetNets

抄録

Multicarrier heterogeneous networks (HetNets) are promising technique of 5th-generation mobile systems to increase system capacity. This paper proposes a personal-cell scheme using an adaptive control cell range expansion (CRE) in multicarrier HetNets, which combined with a macrocell with a carrier frequency of 2.0 GHz and a picocell with a carrier frequency of 3.4 GHz. Average and 5-percentile user throughputs of the proposed adaptive control CRE are presented using system-level computer simulations in comparison with the conventional CRE.

Using these results, we validate the design of the adaptive control CRE in multicarrier HetNets.
