摘要

在即将发布的IEEE802.11ax下一代无线局域网标准中，采用了随机接入正交频分多址(OFDMA)，一种针对具有未知传输缓冲区的sta的上行多用户传输(UL-MU)方法。本文提出了一种基于二维马尔可夫链的OFDMA随机接入性能分析模型。通过计算机仿真，我们证明了该方法在密集环境下的有效性。此外，我们提出了一种计算最优资源单元数的方法，在802.11ax中，它指的是一个子载波的子集，根据数值结果分配用户进行OFDMA随机接入。

Performance evaluation of OFDMA random access in IEEE802.11ax

Random access Orthogonal Frequency Division Multiple Access (OFDMA), a method for uplink multi-user transmission (UL-MU) for STAs with unknown transmit buffer has been adopted in the upcoming IEEE802.11ax next generation wireless LAN standard. In this paper, we propose a performance analysis model which use bidimensional Markov chain model of OFDMA random access. Via computer simulation, we show the usefulness of the proposed method even in the case of dense environment. In addition, we present a method in calculating the optimal number of resource units, which in 802.11ax refer to a subset of subcarriers to assign the user for OFDMA random access from numerical results.
