Collision-Based Up-Link OFDMA Random Access Mechanism for Wi-Fi 6
The IEEE 802.11ax standard defines High-Efficiency WLAN (HEW), which is known as 6th Generation Wi-Fi (Wi-Fi 6) network. HEW uses an up-link OFDMA-based Random Access (UORA) mechanism for channel access in dense multi-user transmissions.

AP-initiated multi-user transmissions in IEEE 802.11ax WLANs [PDF]
Next-generation 802.11ax WLANs will make extensive use of multi-user communications in both downlink (DL) and uplink (UL) directions to achieve high and efficient spectrum utilization in scenarios with many user stations per access point. It will become possible with the support of multi-user (MU) multiple input, multiple output (MIMO) and orthogonal ...
