Performance Analysis of Open Loop Fractional Power Control in LTE Network

Ibrahim Khider; Khalid Hamid Bilal; Anisa Khalf Allah

Long Term Evolution is currently being standardized in 3GPP with the aim of more than twice the capacity over High-Speed Packet Access. The chosen multiple access for uplink is Single Carrier FDMA, which avoids the intra-cell interference typical of CDMA systems, but it is still sensitive to inter-cell interference. As a result, the role of the power control becomes decisive to provide the required SINR, while controlling at the same time the interference caused to neighboring cells. This is the target of the Fractional Power Control (FPC) algorithm lately approved in 3GPP.In the paper, the open loop power control (OLPC) is studied in details to obtain a reference performance, and then some techniques are studied with the aim of improving it. The techniques are implemented on a static simulator. The comparison of the result among the different techniques is carried out by considering key performance indicators like the cell outage and cell throughput.
