摘　　要：中继作为下一代移动通信核心技术之一已受到广泛关注。由于高速下行分组接入(HSDPA)和LTE系统在资源分配上的差异,现有LTE中继系统中的调度算法已不适用于HSDPA中继系统,因此本文提出了一种适合HSDPA中继系统的比例公平调度算法,与没有中继的HSDPA系统以及两层PF调度算法进行比较,系统级仿真结果表明该调度算法能在提高用户吞吐率的同时保证多用户之间公平性要求。Relay as one of the most promising techniques towards the next generation of mobile conununication systems has been widespread concerned, but the introduction of relay in HSDPA systems has not attracted people＇ s attention. Since the re- source allocation has differences between HSDPA and LTE, the schedule scheme of LTE relay system can＇ t be applied to HSDPA relay system. So this paper proposed a new PF schedule scheme for HSDPA relay system. Through system level simulation, the proposed scheme is evaluated and compared with both non - relaying and two - hop PF schedule scheme. Simulation results dem- onstrate that the proposed scheme can improve user＇ s throughput while ensuring fairness requirements of users.
