Wireless device, method, and computer readable media for compressed media access control header and/or compressed acknowledgement are disclosed. The wireless device may include circuitry configured to transmit a media access control (MAC) protocol data unit (MPDU) delimiter with a field that indicates a subsequent MAC header is a compressed MAC header, and transmit a compressed MAC frame with the compressed MAC header. The compressed MAC header does not include one or more of the following group: duration, receive address, and transmit address. The circuitry may be further configured to receive a schedule in a transmission opportunity and receive a second compressed MAC frame. The circuitry may be further configured to determine that the receive address field is an address of the HEW device based on the schedule and determine that the receive address field is an address of an access point that transmitted the schedule based on the schedule.
