AI Technical Summary
Current Wi-Fi protocols, such as 802.11ax, face latency issues in multi-user uplink transmissions, particularly in overlapping Basic Service Sets (OBSS), leading to inefficient channel utilization and increased delay due to reliance on the Access Point (AP) for initiating transmissions.
A new protocol allows non-AP stations to initiate multi-user uplink transmissions in a shared Transmit Opportunity (TXOP) without waiting for a trigger frame, enabling them to schedule channel resources for other stations, thereby improving channel utilization efficiency and reducing latency.
The solution enhances channel utilization and reduces interference and delay in OBSS scenarios, improving flexibility and performance for real-time applications by allowing non-AP stations to independently manage channel access.
