Abstract
In heterogeneous networks containing macro cells and femto cells, power setting is one of the effective techniques to reduce downlink inter-cell interference. In order to diminish inter-cell interference level of the systems and improve system spectrum efficiency, a novel adaptive power setting scheme is proposed and evaluated with other conventional power setting schemes by simulation. Simulation results show that the proposed scheme can improve the edge and average spectrum efficiency of femto cell significantly when there are few indoor macro UEs and reduce system inter-cell interference when there exist macro users close to the femto cell.
