Abstract
To increase LTE (long time evolution) networks spectrum utilization and interference mitigation, a LTE system overlaid with femtocells is studied. The two systems disturb one another with interference. The strategies of the systems are their choices of power allocations in their two bands with regard to individual sum power constraints. Based our prior work, we have derived the Bays-Nash equilibrium a optimal SINR (signal-interference-noise-ratio) threshold. In the paper, with the static non-cooperative power control game, we present a novel distributed power control strategy. That method accelerates the convergence of the Nash game algorithm. The power control scheme can be applied to realistic LTE-femtocell networks to enable robust communication against cross-tier interference thereby obtaining a substantial link quality.KeywordsLTEfemtocellNash equilibrium
