针对中继增强蜂窝系统，提出了一种基于比例公平准则的资源分配算法。在基站和中继节点分别独立地调度所服务用户的情况下，通过资源划分和用户调度两个步骤，实现蜂窝小区内所有用户的比例公平资源分配目标。仿真结果表明，该算法可在保证用户公平性的前提下，获得比传统算法更好的系统吞吐量增益。

This paper proposes a proportional fair(PF) resource allocation algorithm for the OFDMA cellular relay system.Assuming that both the base station(BS) and relay station(RS) can independently schedule users, the proposed algorithm can achieve proportional fairness for all users served by the BS and its subordinate RSs through a two-step resource allocation,i.e.,resource partition and user scheduling.Simulation results demonstrate that the proposed algorithm can achieve a good throughput-fairness trade-off.
