- Abstract
- In LTE cellular network, the uplink power control (PC) mechanism consists of two parts, an open loop (OL) PC and a closed loop (CL) PC. The OLPC determines the initial settings of the network while the CLPC settings aim to correct the errors in the OLPC configurations. In most of cellular networks, OLPC is adopted because of its implementation simplicity and low operation cost. In this work, we investigate the effects of the OLPC parameters for macro and small cells in a heterogeneous network (HetNet) environment. A mathematical analysis is employed to compute a transmit power at the mobile station, a received power at the eNodeB, interferences in the network, and a received signal to interference plus noise ratio (SINR). To achieve the best performance, it would be the appropriate choice of α=1 and P0=-100dBm in the small cells, and α=0.8 and P0=100dBm in macro cell.
