摘要
在正交频分复用系统中分配给HARQ数据缓存区是有限的,为了合理利用有限的数据缓存区,提出了一种HARQ数据缓存区分配和使用控制方法。实际系统测试表明了该方法能够灵活地根据系统当前状态对数据缓存区进行控制管理,解决了传统方法对数据缓存区的浪费以及不能根据信道质量进行实时控制的缺陷,使数据缓存区得到充分利用,提高了整个系统的吞吐量和运行效率。
In OFDMA System, the buffer distributed to HARQ is limited. In order to make proper use of the limited HARQ buffer, a method for distribution and control of HARQ buffer is proposed in this paper. Practical experiment and system test indicate that the proposed method could manage the data buffer according to the current state of the system, solve the problem of buffer waste by traditional methods, make a proper use of the data buffer and improve the throughout and operating efficiency of the whole system.
