INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract This disclosure describes systems, methods, and devices related to awake window (AW) protection. A device may identify a beacon frame received from a first device. The device may identify an information element associated with a first awake window (AW) within the beacon frame. The device may suspend one or more first backoff timers for a duration of the first AW. The device may associate a second backoff timer with a management frame. ## Claims ### Claim at position 1 1-20. (canceled) ### Claim 21 A device, the device comprising processing circuitry coupled to storage, the processing circuitry being configured to: determine a first enhanced distributed channel access (EDCA) access category associated with accessing a medium; determine a suspension of a first backoff timer associated with a first station device for a duration of an awake window (AW) based on the first EDCA access category; cause to send a beacon frame comprising an indication of the AW and the suspension of the first backoff timer; and identify a frame received from a second station device during the first AW based on a second backoff timer. ### Claim 22 (depends on 21) The device of claim 21, wherein the beacon frame is associated with a sweep of beacon frames. ### Claim 23 (depends on 21) The device of claim 21, wherein the frame is an announcement traffic indication message (ATIM) frame. ### Claim 24 (depends on 21) The device of claim 21, wherein the first EDCA category is at least one of a best effort access category, a background access category, a video access category, or a voice access category. ### Claim 25 (depends on 21) The device of claim 21, wherein the first station device is associated with a first basic service set (BSS) of the device. ### Claim 26 (depends on 21) The device of claim 21, wherein the first EDCA category is associated with a first quality of service (QoS). ### Claim 27 (depends on 21) The device of claim 21, further comprising a transceiver configured to transmit and receive wireless signals. ### Claim 28 (depends on 27) The device of claim 27, further comprising an antenna coupled to the transceiver. ### Claim 29 A non-transitory computer-readable medium storing computer-executable instructions which when executed by one or more processors result in performing operations comprising: determining a first enhanced distributed channel access (EDCA) access category associated with accessing a medium; determining a suspension of a first backoff timer associated with a first station device for a duration of an awake window (AW) based on the first EDCA access category; causing to send a beacon frame comprising an indication of the AW and the suspension of the first backoff timer; and identifying a frame received from a second station device during the first AW based on a second backoff timer. ### Claim 30 (depends on 29) The non-transitory computer-readable medium of claim 29, wherein the beacon frame is associated with a sweep of beacon frames. ### Claim 31 (depends on 29) The non-transitory computer-readable medium of claim 29, wherein the frame is an announcement traffic indication message (ATIM) frame. ### Claim 32 (depends on 29) The non-transitory computer-readable medium of claim 29, wherein the first EDCA category is at least one of a best effort access category, a background access category, a video access category, or a voice access category. ### Claim 33 (depends on 29) The non-transitory computer-readable medium of claim 29, wherein the first station device is associated with a first basic service set (BSS) of the device. ### Claim 34 (depends on 29) The non-transitory computer-readable medium of claim 29, wherein the first EDCA category is associated with a first quality of service (QoS). ### Claim 35 A method comprising: determining, by one or more processors, a first enhanced distributed channel access (EDCA) access category associated with accessing a medium; determining a suspension of a first backoff timer associated with a first station device for a duration of an awake window (AW) based on the first EDCA access category; causing to send a beacon frame comprising an indication of the AW and the suspension of the first backoff timer; and identifying a frame received from a second station device during the first AW based on a second backoff timer. ### Claim 36 (depends on 35) The method of claim 35, wherein the beacon frame is associated with a sweep of beacon frames. ### Claim 37 (depends on 35) The method of claim 35, wherein the frame is an announcement traffic indication message (ATIM) frame. ### Claim 38 (depends on 35) The method of claim 35, wherein the first EDCA category is at least one of a best effort access category, a background access category, a video access category, or a voice access category. ### Claim 39 (depends on 35) The method of claim 35, wherein the first station device is associated with a first basic service set (BSS) of the device. ### Claim 40 (depends on 35) The method of claim 35, wherein the first EDCA category is associated with a first quality of service (QoS).
