Abstract:

In LTE cellular networks, the pathloss impacts the performance of the uplink channel power control. Therefore, power control algorithms can achieve good performance on the location where user equipment (UE) is not power limited. The baseline parameter setting of the fractional pathloss power control is valid for some scenarios, however, it is a challenging issue to improve the cell edge throughput in the complex environment, especially the mix of indoor and outdoor UE scenario. This paper proposes a novel interference based power control mechanism. The key is to estimate the interference generated by UEs to other cells. Simulation results show that the proposed mechanism can effectively improve the throughput for UEs with high pathloss. In addition, the proposed mechanism can also reduce the interference from other UEs with low pathloss.
