AI Technical Summary

Technical Problem

In existing wireless communication networks, especially under the IEEE 802.11 standard, there are resource contention and interference issues in the uplink preemption process, resulting in low transmission efficiency and unstable network performance.

Method used

The introduction of the Multi-User Request Transmission (MU-RTS) trigger frame mechanism allows the AP to send requests to multiple STAs simultaneously for CTS frame transmission, optimizing uplink resource allocation and interference management, and achieving more efficient channel utilization.

Benefits of technology

It improves uplink transmission efficiency, reduces interference, enhances network stability and throughput, and improves overall communication quality.
