Femtocell is a promising technology to improve network performance with low-power and cost-beneficial small base stations. However, the interference-limited reality in femtocell networks makes interference and resource management the key to achieving the benefits of femtocell networks. In this paper, the following contributions are made step by step: first, on the basis of the interference temperature...
Investigations on the prior arts on two-tier femtocell networks indicate that the analysis fundamental capacity limit with optimal power and sub-channel adaptation is not well considered. Based on the motivation, mapping the conventional Interference Temperature Model (ITM) to the two-tier femtocell network, the problem model is formulated. Then, we derive a fundamental relation for optimal sub-channel...
