Title
Fairness Analysis of Inter-cell Relay in Downlink OFDMA Cellular Networks
Abstract
In the OFDMA cellular network, in order to improve the throughput of the cell system and the overall resource utilization of the system as well as the quality of service and fairness of the system users. In this paper, we propose a load balancing schema based on the inter-cell relay for the downlink OFDMA cellular networks, and then we research the fairness of intra cell and whole cell system. Based on the frequency reuse pattern, we propose a new type of spectrum division and time slot division model. And then, we calculate the remaining subcarriers by deriving the interference formula according to the SIR. Then, we propose a distance-based fairness scheduling algorithm, which is used for the redistribution of the remaining sub-carriers in the BS and RS region. Besides, we consider the optimization of the relay radius when the fairness of the system is as higher as possible. Finally, the feasibility of the proposed scheme is verified by simulation.
