论文摘要
Wi-Fi 7已经在制造中，多连锁操作（MLO）是其通讯IEEE 802.11BE修正案中提出的主要功能之一。 MLO将允许设备协调多个无线电接口，以通过单个关联访问单独的通道，以改善吞吐量，网络延迟和整体频谱重用效率。在这项工作中，我们研究了三种参考方案，以评估两个主要的MLO实现的性能 - 多链接多链接多拉迪奥（MLMR）和多链接单速度（MLSR），即采用它们的多个节点之间的相互作用，以及它们与遗留单链接设备的共存。重要的是，我们的结果表明，MLMR的潜力主要在孤立的部署或未载的网络条件下释放。取而代之的是，在中型到高负载方案中，MLSR可能会更有效地减少潜伏期，同时通过竞争单链节点来保证公平性。
Wi-Fi 7 is already in the making, and Multi-Link Operation (MLO) is one of the main features proposed in its correspondent IEEE 802.11be amendment. MLO will allow devices to coordinate multiple radio interfaces to access separate channels through a single association, aiming for improved throughput, network delay, and overall spectrum reuse efficiency. In this work, we study three reference scenarios to evaluate the performance of the two main MLO implementations -- Multi-Link Multi-Radio (MLMR) and Multi-Link Single-Radio (MLSR) -- , the interplay between multiple nodes employing them, and their coexistence with legacy Single-Link devices. Importantly, our results reveal that the potential of MLMR is mainly unleashed in isolated deployments or under unloaded network conditions. Instead, in medium- to high-load scenarios, MLSR may prove more effective in reducing the latency while guaranteeing fairness with contending Single-Link nodes.
