Multi-link Operation (MLO) was introduced into 802.11be as a promising technology to improve throughput and provide Quality of Services (QoS) guarantees. In this article, we start by introducing the multi-link transmission issues for MLO. Particularly, we focus on the channel access issue, and we present the recently proposed channel access schemes in the latest 802.11 draft. More importantly, we propose the novel channel access schemes under the three different scenarios to increase the link utilization. Finally, we conduct simulations to demonstrate that the multi-link transmission can effectively improve the throughput performance.
