Throughput Analysis of MacroUE for Varied Transmit Power of Small Cell in Heterogeneous Network

摘要

Femtocells are the solution introduced in long-term evolution-advanced (LTE-A) network to enhance the data rate and coverage of indoor users. The deployment of femtocell over macrocell is known as heterogeneous networks (HetNets). The available spectrum is shared between macrocell and femtocell in order to improve the system performance. However, the unplanned deployment of femtocell causes severe interference to macrocell and vice versa. The interference can be either co-tier or cross-tier. The objective of this research is to mitigate cross-tier interference experienced by Macro User Equipment (MUE) when placed within the vicinity of femtocell. The performance of the proposed analysis is examined in terms of signal-to-interference-plus-noise ratio (SINR) and throughput. From the simulation results, it is found that as the distance between MUE and macrocell decreases, throughput and SINR experienced by the MUE increase and vice versa.
