Add to ORKG[[abstract]]In wireless broadband access networks, most indoor environment encounters serious coverage problem due to non-line of sight transmission. To improve the coverage, femtocell has been introduced as a promising technology. However, the deployment of femtocells may introduce extra interference to macrocell base stations. An effective interference management mechanism is required to optimize the system performance. In this paper, a resource allocation algorithm is proposed to resolve the two-tier downlink interference problem. The proposed scheme combines fractional frequency reuse (FFR) in macrocell and a heuristic graph-based channel assignment algorithm in femtocell to reduce the interference problem. Simulation results reveal tha...
