A Distributed Algorithm Combining Power Control and Scheduling for Femtocell Networks
In this paper, the authors present a distributed algorithm combining power control and scheduling for densely deployed femtocells networks. The strong interference in the downlink from the femtocells should be well mitigated to satisfy the Quality of Service (QoS) requirement of femtocell users. The considered optimization problem is formulated as minimizing the total power consumption, while the QoS requirements of femtocell users are guaranteed. An optimal scheme requires global information of channel qualities, which is very difficult to put into practice. This paper proposed a suboptimal algorithm joining power control with scheduling policy, which is operated in distributed manner.
