Abstract

The rise in mobile data traffic demands from indoor users (UEs) coupled with poor cellular coverage in indoor environments, triggering the growth of Femto cell deployments. However, due to densification of Femtos, frequency reuse one, and lack of coordination among Femtos in LTE HetNets, cell-edge users of Macro cells, who are in the vicinity of Femtos, get affected by cross-tier interference of the Femtos. In this work, we investigate how to improve performance of Victim Macro UEs (VMUEs). In order to provide better coordination between interfering Macro and Femtos, a centralized algorithm is proposed which performs Femto muting via joint Almost Blank Subframe (ABSF) and power control. During ABSF, Femto automatically adjusts its transmission power depending on the level of interference suffered by VMUEs. Our proposed scheme, called as RrMute, is compared with baseline schemes and the simulation results show that RrMute enhances the performance of VMUEs without jeopardizing the performance of Femto UEs in LTE HetNets.
