Modified proportional fair for LTE femto cells with eICIC

In this paper, heterogeneous LTE network is considered where femto cells are randomly deployed in a macro network. Femto cells are modeled as closed cells, namely only group member UEs can be associated with the femto cells. We propose modified proportional fair scheduling algorithms for heterogeneous network containing macro and femto cell and Compared to the existing proportional fair scheduling algorithms. We show how some features of mitigation interference. we show effect of femto autonomous power control for adjusting femto transmitted power, also we use almost blank subframe (ABS) feature in our simulation which will be as time multiplexing for enhanced interference coordination scheme (eICIC). Through computer simulation we assist the effect of power control and ABS in the simulation, also we show the effect of modified proportional fair scheduling on user throughput and cell throughput, we compared these results with PF.
