Femtocells have attracted growing attentions in academia, industry, and standardization forums in recent years. In this paper, we investigate a distributed radio resource allocation scheme to maximize the energy-efficiency in uplink OFDMA dense femtocell networks. We model the subchannel allocation and power control problem as a non-cooperation game. Due to the fact that joint subchannel allocation...
In this paper, a novel joint resource allocation including sub-channel scheduling and power control is proposed for downlink multi-cell orthogonal frequency division multiple access (OFDMA) networks. We provide a utility function consisting of energy efficiency and interference pricing, in which power and sub-channel resources have been jointly considered. To reduce the complexity of the joint resource...
