1. A method for wireless communication performed by a wireless communication device, comprising:
transmitting, in association with establishing a restricted target wake time (TWT) session on a wireless medium for one or more wireless stations (STAs), a management frame including a TWT parameter set field that includes one or more TWT parameters associated with the restricted TWT session, the one or more TWT parameters indicating that the restricted TWT session includes one or more restricted TWT service periods (SPs) that are available for communications on the wireless medium with the one or more STAs and that are unavailable for communications on the wireless medium with other STAs, the one or more STAs associated with latency sensitive traffic and the other STAs associated with a non-latency sensitive traffic; and
transmitting latency sensitive data to, or receiving latency sensitive data from, the one or more STAs during at least one restricted TWT SP of the one or more restricted TWT SPs, wherein, in accordance with the one or more TWT parameters, each of a set of STAs is to terminate a respective transmit opportunity on the wireless medium at or before a start of each restricted TWT SP of the one or more restricted TWT SPs.
