PHYSICAL LAYER LATENCY REDUCTION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18296772 titled 'PHYSICAL LAYER LATENCY REDUCTION
Simplified Explanation
This patent application discusses methods for reducing latency in the physical layer of wireless communication systems by inserting low-latency traffic into transmission opportunities occupied by non-low-latency traffic.
- The patent application focuses on PHY protocol data unit (PPDU) designs that allow for the insertion of low-latency traffic during a transmission opportunity.
- An access point (AP) can aggregate low-latency PPDU subframes and insert them into an aggregated PPDU during a transmission opportunity.
- Wireless stations (STAs) can detect and decode the low-latency PPDU subframes within the aggregated PPDU.
Key Features and Innovation
- Support for inserting low-latency traffic into transmission opportunities occupied by non-low-latency traffic.
- Aggregated PPDU design that includes low-latency PPDU subframes.
- Detection and decoding of low-latency PPDU subframes by wireless stations.
Potential Applications
- Wireless communication systems requiring low-latency data transmission.
- Applications where real-time data delivery is critical.
- Networks with mixed traffic types that need to prioritize low-latency traffic.
Problems Solved
- Reducing latency in wireless communication systems.
- Efficient utilization of transmission opportunities.
- Prioritizing low-latency traffic in mixed traffic environments.
Benefits
- Improved real-time data delivery.
- Enhanced performance in latency-sensitive applications.
- Optimal use of available transmission opportunities.
Commercial Applications
Wireless communication networks in industries such as:
- Telecommunications
- Internet of Things (IoT)
- Autonomous vehicles

Original Abstract Submitted
This disclosure provides methods, components, devices and systems for physical layer (PHY) latency reduction. Some aspects more specifically relate to PHY protocol data unit (PPDU) designs that support inserting low-latency traffic into a transmission opportunity (TXOP) occupied by non-low-latency traffic. In some implementations, during a TXOP, an access point (AP) may output an aggregated PPDU (A-PPDU) that is aggregated in a time domain and includes an A-PPDU header and one or more A-PPDU subframes. The AP may obtain, from an application layer, a low-latency PPDU (LL-PPDU) subframe and may insert the LL-PPDU subframe in place of at least one of the one or more A-PPDU subframes. The AP may output the LL-PPDU subframe during the TXOP. A wireless station (STA) receiving the A-PPDU header and the one or more A-PPDU subframes may detect the presence of the LL-PPDU subframe and may receive and decode the LL-PPDU subframe.
