Optimal power control scheme in LTE networks based on utility function

In this paper, transmission power control problem for uplink LTE network is investigated and a new autonomic uplink power control scheme was proposed based on utility function, which is a self-organized algorithm. The whole approach is based on the economic concept named utility function. The proposed scheme is solved through the Lagrange multiplier technique. It is proved that the utility function based algorithm is applicable and the optimal power level can be achieved based on our model.
