QoS-Aware Autonomous Distributed Power Control in Co-Channel Femtocell Networks

Executive Summary

FemtoCells (FCs) are small-area cellular networks deployed over a MacroCell (MC) network. Typically, FCs are independent of each other and of the underlying MC, thereby necessitating distributed non-cooperative resource allocation schemes. This paper develops a new distributed autonomous UpLink (UL) Power Control (PC) scheme for Femto Users (FUs). The authors' work aims at maintaining the minimum required Signal to Interference plus Noise Ratio (SINR) for a maximum number of FUs via distributed QoS-aware stochastic power allocation to FUs. They evaluate the performance of their proposed solution and compare it with existing power allocation techniques. Results show that their scheme yields a significant performance improvement in terms of percentage of satisfied users when compared with these existing solutions.
