摘要
Recently, wireless networks have been an essential element in people's lives. With the booming development of real-time applications (RTA), such as multimedia streaming, VR reality, online conferences, etc., the transmission rates required by these applications have been increasingly high. To solve the problem of dense and heavy network transmission, IEEE 802.11ax provides an Uplink OFDMA Random Access (UORA) transmission mode. However, when too many STAs are delivering data, data transmission delays are often long and network performance is frequently not high. To meet the low-latency sensitive network needs of real-time applications, this study proposes an IEEE 802.11be transmission scheme which adjusts the OFDMA Backoff (OBO) calculation for STAs according to the priorities level of data streams. STAs with higher priority levels can transmit data with higher priorities, thereby improving the transmission efficiency of latency-sensitive data streams and enhancing the Quality of Experience (QoE) for users on the receiving end.
