MANAGING EDCA PARAMETERS WITH LOW LATENCY RELIABLE TRAFFIC - A simplified explanation of the abstract
This abstract first appeared for US patent application 18258317 titled 'MANAGING EDCA PARAMETERS WITH LOW LATENCY RELIABLE TRAFFIC
Simplified Explanation
The abstract of the patent application describes a network that implements measures to prioritize Low Latency Reliable Service (LLRS) traffic over non-LLRS traffic. LLRS-capable and non-capable stations coexist and share the same wireless medium. Non-capable stations continue ongoing legacy contention-free transmissions regardless of the need for LLRS transmission, causing LLRS transmissions to wait for a long time before starting. The Access Point (AP) detects LLRS activity and modifies the Enhanced Distributed Channel Access (EDCA) TXOP limit parameter of a Basic Service Set (BSS) to force stations to reduce their TXOP while LLRS activity is ongoing. The AP can organize separate BSSs for LLRS-capable and non-capable stations, and refusal or disassociation from a BSS can indicate to the stations that a BSS better suited to their LLRS capability is available.
- The network gives priority to LLRS traffic over non-LLRS traffic.
- LLRS-capable and non-capable stations coexist and share the same wireless medium.
- Non-capable stations continue ongoing legacy contention-free transmissions, causing delays for LLRS transmissions.
- The AP detects LLRS activity and modifies the EDCA TXOP limit parameter of a BSS to reduce TXOP for stations during LLRS activity.
- Separate BSSs can be organized for LLRS-capable and non-capable stations.
- Refusal or disassociation from a BSS can indicate the availability of a BSS better suited to LLRS capability.
Potential applications of this technology:
- Real-time communication systems that require low latency and reliability, such as video conferencing, online gaming, and telemedicine.
- Industrial automation and control systems that rely on timely and reliable data transmission.
- Autonomous vehicles and drones that require low latency communication for navigation and control.
Problems solved by this technology:
- Prioritizes LLRS traffic, ensuring timely and reliable transmission for critical applications.
- Reduces delays caused by non-capable stations in the network, improving overall network performance.
- Allows for the organization of separate BSSs, providing better adaptation to the LLRS capability of stations.
Benefits of this technology:
- Improved quality of service for LLRS traffic, ensuring low latency and reliability.
- Efficient utilization of the wireless medium by reducing delays caused by non-capable stations.
- Flexibility in organizing separate BSSs for LLRS-capable and non-capable stations, optimizing network performance.
Original Abstract Submitted
A network adopts Low Latency Reliable Service measures to ensure LLRS traffic has priority over not-LLRS traffic. LLRS capable and not-capable stations coexist and share the same wireless medium. LLRS not-capable stations complete an ongoing legacy contention free transmission TXOP regardless of any needs of station to transmit LLRS. LLRS transmissions thus wait for a long time before starting. An AP detects LLRS activity in the network and modify the EDCA TXOP limit parameter of a BSS to force the stations to reduce their TXOP while LLRS activity remains. The AP can organize a BSS for LLRS capable stations and another BSS for LLRS not-capable stations. Refusal for association to such BSSs or disassociation from such BSSs can include a code indicating to the refused/disassociated stations that a BSS more adapted to its LLRS capability is available.
