中继增强的LTE-A网络中的频谱复用方案研究

his paper proposed two frequency reuse-based resource management schemes in relay-enhanced LTE-Advanced network. Based on these schemes, interference distribution and bandwidth allocation as well as throughput of the system are analyzed. The computer simulation is accomplished to compare the system performance under these schemes, including: distribution of SNR, bandwidth utilization ratio, cellular throught and fairness of resource allocation to the users, etc. The simulation results show that the proposed schemes improve throughput and bandwidth utilization ratio greatly compared with traditional resouce assignment scheme.
