1. A method for wireless communication by a wireless communication device, comprising:
acquiring first coordinated restricted target wake time (r-TWT) signaling information associated with one or more first r-TWT service period (SP) schedules associated with a first overlapping basic service set (OBSS);
transmitting a management frame comprising a broadcast target wake time (TWT) element, wherein the broadcast TWT element comprises r-TWT schedule information indicating one or more second r-TWT SP schedules associated with a basic service set (BSS) associated with the wireless communication device and comprises r-TWT coordination information indicating the one or more first r-TWT SP schedules associated with the first OBSS, wherein the one or more second r-TWT SP schedules are orthogonal to the one or more first r-TWT SP schedules in time based on the first coordinated r-TWT signaling information; and
communicating with one or more first wireless stations (STAs) during the one or more second r-TWT SP schedules based on a respective latency requirement of each of the one or more first STAs.
