摘要：
Time-sensitive applications, such as industrial automation and extended reality (XR), require packets to be delivered within tight latency bounds and with high reliability. Meeting those requirements over Wi-Fi links is challenging even considering the efficient scheduling techniques provided by the latest Wi-Fi generations (e.g., based on IEEE 802.11ax). In this paper we introduce the concept of Scheduled Transmission Opportunities (S-TXOP) where the network controller exploits the deterministic traffic pattern associated with most time-sensitive applications to minimize the control overhead and provide scheduled channel access that can meet very low latency cycles. Our results show that the S-TXOP meets those challenges with higher robustness and efficiency compared to existing scheduling techniques in 802.11
