IEEE 802.11ay supports multi-user multiple-input-multiple-output (MU-MIMO). However, the MU-MIMO beamforming training (BFT) is a time-consuming process for finding appropriate directional antenna patterns, and inefficient BFT results in a long training time. Thus, in this letter, we propose an algorithm that configures the transmit antenna with the aim of reducing the number of redundant transmissions during MU-MIMO BFT. Both analytic and simulation results show that our proposed algorithm can significantly reduce the training time.

适用于 IEEE 802.11ay WLAN 的高效 MU-MIMO 波束成形协议

IEEE 802.11ay 支持多用户多输入多输出 (MU-MIMO)。然而，MU-MIMO 波束成形训练 (BFT) 是寻找合适定向天线方向图的耗时过程，而低效的 BFT 会导致训练时间过长。因此，在这封信中，我们提出了一种配置发射天线的算法，目的是减少 MU-MIMO BFT 期间的冗余传输次数。分析和仿真结果都表明，我们提出的算法可以显着减少训练时间。
