Abstract

The power control (PC) policy in Long Term Evolution (LTE) network is important issue, the interference of cell user to neighbour cell is consider to avoid any annoying to close cells. In this paper the two uplink PC scheme close loop power control (CLPC) and open loop power control (OLPC) are modelled in order to investigate the effects of Mobile cell edge to another cell and show how to adjust the user power according to two path losses. The algorithms were simulated by using MATLAB program. The open loop technique considered that the strongest interference is caused by mobile to neighbour cell, while the power control components is adjusted continuously in the close loop technique. The effects of CLPC and OLPC are shown in term of throughput, path loss, power spectrum density (PSD) and the bit error rate (BER). Results shows that the CLPC is outperform the OLPC in term of throughput, PSD and path loss; while they are perform similarly in term of BER.
