PREEMPTION FOR LOW LATENCY APPLICATION BY USING NULL TONES OR DEDICATED RESOURCE UNIT (RU) FOR SUSPEND REQUEST FEEDBACK - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240022383 titled 'PREEMPTION FOR LOW LATENCY APPLICATION BY USING NULL TONES OR DEDICATED RESOURCE UNIT (RU) FOR SUSPEND REQUEST FEEDBACK
Simplified Explanation
The patent application describes a system, method, and devices for low latency preemption in wireless communication. Here is a simplified explanation of the patent:
- The invention focuses on enabling low latency transmission by establishing time gaps between consecutive data units in the physical layer convergence protocol.
- These time gaps allow for preemption opportunities, where a higher priority transmission can interrupt a lower priority transmission.
- The device detects a suspend/resource request (SR) sent by a station device (STA) over predefined null tones.
- It determines if the current transmit opportunity (TXOP) can be preempted and communicates this status through a control frame.
- The device also sets a suspend request (SR) feedback report support subfield within an ultra high reliability (UHR) capabilities element based on its capability to support the SR feedback report.
Potential applications of this technology:
- Low latency preemption can be beneficial in various wireless communication systems, such as Wi-Fi networks, cellular networks, and IoT devices.
- It can improve real-time applications that require low latency, such as video streaming, online gaming, and voice communication.
- This technology can also be useful in mission-critical applications, where timely transmission is crucial, such as emergency services and industrial automation.
Problems solved by this technology:
- Low latency preemption addresses the issue of delays in wireless communication, ensuring that time-sensitive data can be transmitted promptly.
- It allows for efficient utilization of the wireless medium by prioritizing critical transmissions over less time-sensitive ones.
- This technology helps in reducing latency and improving overall system performance, enhancing the user experience in various applications.
Benefits of this technology:
- The ability to establish time gaps and facilitate preemption opportunities enables low latency transmission, which is essential for real-time applications.
- By supporting suspend/resource requests and preempting lower priority transmissions, this technology ensures timely delivery of critical data.
- It improves the reliability and efficiency of wireless communication systems, leading to enhanced performance and user satisfaction.
Original Abstract Submitted
this disclosure describes systems, methods, and devices related to low latency preemption. a device may establish time gaps between consecutive physical layer (phy) convergence protocol data units (ppdus) to facilitate preemption opportunity for low latency (ll) transmission. the device may detect a suspend/resource request (sr) transmitted over predefined null tones, wherein the sr is received from a station device (sta). the device may determine if a current transmit opportunity (txop) is preemptable and communicate this status through a control frame. the device may set a suspend request (sr) feedback report support subfield within an ultra high reliability (uhr) capabilities element based on a capability to support the sr feedback report.
