LOW LATENCY SOLUTIONS FOR RESTRICTED TARGET WAKE TIME (R-TWT) DURING MULTI-LINK OPERATION (MLO) - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240340788 titled 'LOW LATENCY SOLUTIONS FOR RESTRICTED TARGET WAKE TIME (R-TWT) DURING MULTI-LINK OPERATION (MLO)

The patent application discusses systems, methods, and apparatus for protecting latency-sensitive communications among multi-link devices (MLDs).

• An access point (AP) MLD can establish multiple communication links with a non-AP MLD and schedule a Restricted Target Wake Time (R-TWT) Service Period (SP) on one of the links.
• When a Transmit Opportunity (TXOP) acquired on a non-R-TWT link overlaps the R-TWT SP, the TXOP may be extended to support an exchange of latency-sensitive traffic.
• TXOPs occurring on non-R-TWT links may be terminated before the start of the R-TWT SP to allow for the exchange of latency-sensitive traffic on the R-TWT link during the SP.
• The AP MLD can schedule SPs on multiple communication links and transfer a TWT agreement between the communication links.

Potential Applications: - Wireless communication systems - Internet of Things (IoT) devices - Industrial automation

Problems Solved: - Ensuring latency-sensitive communications are protected - Efficient scheduling of communication links - Optimizing data exchange between MLDs

Benefits: - Improved reliability of latency-sensitive communications - Enhanced network performance - Better utilization of communication links

Commercial Applications: Title: "Enhanced Latency-Sensitive Communication Systems for Wireless Networks" This technology can be applied in industries such as telecommunications, smart cities, and autonomous vehicles to enhance real-time data exchange and improve network efficiency.

Questions about the technology: 1. How does this technology improve the reliability of latency-sensitive communications? 2. What are the potential implications of transferring a TWT agreement between communication links?

Original Abstract Submitted

this disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for protecting latency-sensitive communications among multi-link devices (mlds). an access point (ap) mld may establish multiple communication links with a non-ap mld and schedule a restricted target wake time (r-twt) service period (sp) on one of the links (the “r-twt link”). in some aspects, when a transmit opportunity (txop) acquired on a non-r-twt link overlaps the r-twt sp, the txop may be extended to support an exchange of latency-sensitive traffic on the non-r-twt link. in some other aspects, any txops occurring on non-r-twt links may be terminated prior to the start of the r-twt sp so that latency-sensitive traffic can be exchanged on the r-twt link during the sp. an ap mld also may schedule sps on multiple communication links. in some aspects, the ap mld may transfer a twt agreement between the communication links.
