| Abstract | In LTE heterogeneous networks, cross-tier interference between macrocell and smallcells i.e., picocells, can be eliminated by reserving certain periods termed as Almost Blank Subframes (ABS periods) for smallcells transmission. However, co-tier interference among smallcells during ABS periods remains a significant problem which reduces the network performance. In this paper, we consider a distributed power control scheme for downlink co-tier interference coordination in two-tier LTE heterogeneous networks. In our proposed distributed algorithm, all pico access points simultaneously update their transmit power to maximize their individual payoff functions according to a best response function in a non-cooperative game. Our numerical simulation quickly towards Nash equilibrium points. |
