摘要：
This paper investigates downlink frequency resource coordination for LTE network that comprises of macrocell and femtocell. Due to the requirement of high data rate for indoor coverage, femtocells have been considered as a potential solution recently. However, owing to their random and uncoordinated deployment, cross-tier interference exists and affects the system throughput seriously. A hybrid resource allocation (HRA) technique based on measurement reports both from macro users (MUEs) and femto users (FUEs) is proposed. Simulation results show that proposed scheme can enhance overall throughput and mitigate major interferences in different scenarios.
