Abstract
A wireless communication protocol using CSMA/CA, EDCA and R-TWT to prioritize RTA traffic transmissions. During an R-TWT SP, the RTA traffic is prioritized for transmission and mechanisms are provided for assuring proper indications and termination of the R-TWT SP. During this process, member STAs communicate with the R-TWT scheduling AP when they have no more frames to send. The R-TWT scheduling AP can also terminate the R-TWT SP before its scheduled end time, allowing non-member STAs to immediately contend for the channel. In addition, the R-TWT scheduling AP can exchange frames with STAs, that have an R-TWT feature but are not R-TWT member STAs, after frame exchanges with the R-TWT member STAs during the R-TWT SP have been completed.
