  • Publication number: 20230051808
    Abstract: Embodiments of the present invention provide A TID-based RTWT SP that can be configured for either trigger-based transmission or EDCA-based transmission for time sensitive traffic to reduce the chance of contention/collision on time sensitive traffic caused by non-time sensitive traffic using an EDCA mechanism. This can also reduce the chance of contention on time sensitive traffic when both trigger-based transmission and EDCA-based-transmission are used in the same TID-based RTWT SP. The AP MLD can dynamically adjust the schedule of TID-SPs for ether trigger-based or EDCA-based transmission and announce the new schedule of the TID-SPs according to the requirements of time sensitive traffic and/or traffic load condition, and can prioritize time sensitive transmission to meet QoS requirements.
