摘要： An AP receives a frame comprising an indication of a restricted target wake up time schedule service period (r-TWT SP) from a wireless device. The AP one or more of adjusts an r-TWP SP of the AP based on the indication of the r-TWT SP indicated in the received frame and announcing that an STA associated with the AP is to terminate a transmit opportunity (TXOP) before the r-TWT SP indicated in the received frame begins.
