Abstract: In order to resolve the interference caused by the deployment of Femtocells in Macrocell, a co-tier interference and cross-tier interference coexistent model is proposed. By means of interference factor, the whole interference network is parted into co-tier-dominated, cross-tier-dominated and balanced areas. According to interference model and reasonable interference factor, the co-tier interference or cross-tier interference can be considered alone without impairing the performance of the Femtocell users. The probability distribution of the three areas is studied, which can provide theoretical guidance for practical project when laying out Femtocells in Macrocell. It can reduce the complicity of spectrum allocation, power control and access management.

Key words: communication technology, interference management, qualitative analysis of interference, femtocell, co-tier interference, cross-tier interference
