提出了一种应用于B3G TDD系统的随机接入方案。该方案结合了媒体接入层的包调度和物理层的信号处理技术,可以有效地避免数据包的碰撞。分析比较和仿真表明,该方案较传统的时隙ALOHA随机接入方案在吞吐率和时延方面都有较大的改善。
A random access scheme applied to B3G TDD system is proposed. The solution combines packet scheduling at the media access layer and signal processing at the physical layer to effectively avoid data packet collisions. The analysis and comparison show that this scheme has a better improvement in throughput and delay than the traditional slotted ALOHA random access scheme.
