Distributed Frequency Resource Control for Intercell Interference Control in Heterogeneous Networks

Free registration required

Executive Summary

In Heterogeneous Cellular Networks (HCN) which consists of macrocells and numerous picocells, efficient interference management schemes between macrocells and picocells are so crucial to the overall system performance. The authors propose a Dynamic Cooperative Silencing control (DCS) scheme for Inter-Cell Interference Control (ICIC). It is a low-complex, low-feedback and distributed algorithm using only strongly interfered neighboring users' information. The system simulation shows that the system performance and in particular the cell-edge throughput is significantly increased with the proposed silencing scheme.
