Dynamic fractional power control for LTE uplink

Recently, the 3^rd Generation Partnership Project has standardized a power control mechanism for the uplink of the Long Term Evolution system. This mechanism is based on the fractional compensation of the pathloss, also known as fractional power control. This approach decreases inter-cell interference but may impact the throughput. In this paper, a novel approach power control will be proposed to avoid such throughput loss. This method still uses fractional power control principle, but differentiates between users generating high interference and users generating low interference. Our simulations indicate that the proposed power control has better performance than the fractional power control.
