Abstract: Methods and apparatus are contemplated for transmission of data in a wireless local area network. In embodiments, a first wireless device (AP) is configured to transmit data packets to a second wireless device (STA), and transmits an initial control frame (ICF) to the STA indicating a transmission opportunity time period (TXOP) for data transfer from the first wireless device to the second wireless device.

Responsive to receipt of the ICR or UUA, the AP may modify a transmission plan, e.g., shorten or cancel the TXOP, or transmit a portion of the data to another STA, etc. Power settings may be determined based on the unavailability time period.
