Range-Based Scheme for Adjusting Transmission Power of Femtocell in Co-Channel Deployment

In heterogeneous networks, femtocells are introduced to improve the network capacity. However, dense deployment of femtocells leads to undesirable interference, which degrades the performance of the system. The interference can be managed and mitigated based on different approaches such as resource allocation or transmission power control. Controlling the femtocell transmission power is one of the factors that can be considered to alleviate undesirable effect of the interference. Also, it can be used to support auto-configuration conductance of the network. In this work, transmission power auto-configuration approach is proposed. The proposed approach is based on the macrocell transmission power and femtocell coverage. The simulation results depict that the capacity of the network is improved, and the interference is alleviated.
