Abstract
Enhanced R-TWT scheduling is performed in which the R-TWT scheduling AP can perform scheduling quickly to react quickly to changes in the network environment and optimize R-TWT scheduling for efficiency and stability. The R-TWT scheduling AP transmits R-TWT trigger frames and is able to collect information from R-TWT scheduled STAs which may affect R-TWT scheduling. The scheduling can take into account that some member STAs may be dozing (asleep) for several beacon intervals and do not wake up for the beacon, then the R-TWT scheduling AP initiates the update of parameters when needed to check on those STAs to determine if any updates are needed. The R-TWT trigger frame can allocate resource units (RU) for R-TWT scheduled STAs to communicate back to the R-TWT scheduling AP.
