在本文中，我们提出了一种基于基础设施的网络的多频段媒体访问控制（MAC）协议，该网络具有支持带内全双工（IBFD）和多用户传输到多频段站的接入点（AP）。多频段全双工 MAC (MB-FDMAC) 协议主要使用 6 GHz 以下频段进行控制帧交换，按照 IEEE 802.11 标准以最低速率传输，并使用具有更高瞬时带宽的 60 GHz 频段专门用于数据帧交换。我们还提出了一种确保上行链路和下行链路站之间公平的选择方法。我们的结果表明，与最先进的 MAC 协议相比，MB-FDMAC 有效地将毫米波频段的频谱效率提高了 324%、234% 和 189%。此外，MB-FDMAC 的综合吞吐量显着优于独立运行的 6 GHz 以下和 60 GHz IBFD 多用户 MIMO 网络 85% 以上。此外，我们通过评估站点之间的吞吐量、数据包延迟和公平性的变化，研究了多个网络变量，例如网络中站点的数量、毫米波频段站点的百分比、竞争阶段的大小以及MB-FDMAC的选择方法。最后，我们提出了一种通过将时间双工合并到 MB-FDMAC 中来提高毫米波频段高带宽利用率的方法，我们证明该方法可以将公平性提高 12.5%，并将数据包延迟显着降低 80%。
In this paper, we propose a multi-band medium access control (MAC) protocol for an infrastructure-based network with an access point (AP) that supports In-Band full-duplex (IBFD) and multiuser transmission to multi-band-enabled stations. The Multi-Band Full Duplex MAC (MB-FDMAC) protocol mainly uses the sub-6 GHz band for control-frame exchange, transmitted at the lowest rate per IEEE 802.11 standards, and uses the 60 GHz band, which has significantly higher instantaneous bandwidth, exclusively for data-frame exchange. We also propose a selection method that ensures fairness among uplink and downlink stations. Our result shows that MB-FDMAC effectively improves the spectral efficiency in the mmWave band by 324%, 234%, and 189% compared with state-of-the-art MAC protocols. In addition, MB-FDMAC significantly outperforms the combined throughput of sub-6 GHz and 60 GHz IBFD multiuser MIMO networks that operate independently by more than 85%. In addition, we study multiple network variables such as the number of stations in the network, the percentage of mmWave band stations, the size of the contention stage, and the selection method on MB-FDMAC by evaluating the change in the throughput, packet delay, and fairness among stations. Finally, we propose a method to improve the utilization of the high bandwidth of the mmWave band by incorporating time duplexing into MB-FDMAC, which we show can enhance the fairness by 12.5 % and significantly reduces packet delay by 80%.
