Abstract
Conference Title: 2014 4th International Conference on Wireless Communications, Vehicular Technology, Information Theory and Aerospace & Electronic Systems (VITAE) Conference Start Date: 2014, May 11 Conference End Date: 2014, May 14 Conference Location: Aalborg, Denmark 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.
