The automatic configuration of transmit power in LTE networks based on throughput estimation

Abstract

We present an optimization method for automatic selection of downlink transmit power of LTE eNodeB based on the estimated throughput of the network. The procedures provide self optimized network functions to minimize the inter-cell interferences and maximizing the radio resource utilization. We propose a method based on the expected link throughput based on uniform client spatial distribution and compare our approach with solution based on SINR. We show simulation results that prove that the proposed method gives higher average link rate per client and higher total network throughput than optimization methods shown in the literature.
