Abstract
Wireless IEEE 802.11 communication mechanisms are described for a member STA of a R-TWT SP to gain TXOP channel access before the R-TWT SP, which does not need to end before the start time of the R-TWT SP. On trigger based R-TWT SP, the TXOP time is shared to overlap the R-TWT SP; allowing the AP to behave as the TXOP holder for the frame exchange of latency sensitive traffic during the R-TWT SP. Thus, the R-TWT scheduling AP and member STAs of a R-TWT SP can contend for the channel together before the scheduled start time of the R-TWT SP. When one of these STAs gains channel access, it can reserve a TXOP until the scheduled end time of the R-TWT SP, which may extend beyond the normal TXOP limit.
