Femtocells are viewed as a promising option for mobile operators to improve coverage and provide high-data-rate services in a cost-effective manner. However, cross-tier interference mitigation is considered to be one of the major challenges. Distributed-game-based power control approaches are effective for interference management in wireless networks. In this paper, we focus on the optimal power allocation...
This paper is concerned with the dead zone problem of uplink communication in two-tier femtocell network. In the uplink communication, the interference generated by a macrocell user at the edge of the macrocell base station (MBS) coverage area may cause the signal-to-interference-plus-noise ratio (SINR) received at the nearby femtocell base station (FBS) below the requirement, and the region in which...
