CLAIMS
What is claimed is:
1. A device, the device comprising memory and processing circuitry, configured to:
identify a physical layer (PHY) protocol data unit (PPDU) received from a station device,
the PPDU comprising an aggregate media access control protocol data unit (A-MPDU), wherein the A-MPDU comprises a plurality of media access control protocol data units (MPDUs);
determine a status for each of the plurality of MPDUs;
determine an acknowledgement (ACK) report based on the status for each of the plurality of MPDUs; and
cause to transmit a response PPDU comprising a lightweight (LW) ACK to the station device.
2. The device of claim 1, wherein, to determine the acknowledgement report, the
memory and the processing circuitry are further configured to:
determine a value from a frame check sequence field for each of the plurality of MPDUs; and
generate the ACK report based at least in part on the value from the frame check sequence field for each of the plurality of MPDUs.
3. The device of claim 2, wherein the memory and the processing circuitry are further
configured to:
generate a bitmap based on the ACK report; and wherein the LW ACK comprises the bitmap.
4. The device of claim 1, wherein the PPDU comprises an indication that an immediate LW ACK is requested.
5. The device of claim 4, wherein the indication is a trigger type specified in a subfield of a media access control (MAC) header of the A-MPDU.
6. The device of claim 1, wherein the memory and the processing circuitry are further configured to determine the A-MPDU from the PPDU.

7. The device of claim 6, wherein a PHY component determines the A-MPDU from the PPDU.
8. The device of claim 1, wherein the LW ACK is stored to the LW-ACK field of the response PPDU.
9. The device of any one of claims 1-8, further comprising a transceiver configured to transmit and receive wireless signals.
10. The device of claim 9, further comprising one or more antennas coupled to the transceiver.
11. A non-transitory computer-readable medium storing computer-executable instructions which when executed by one or more processors result in performing operations comprising:
generating an aggregate media access control protocol data unit (A-MPDU) comprising a plurality of media access control protocol data units (MPDUs);
causing to send a physical layer (PHY) protocol data unit (PPDU) comprising the A-MPDU to a device; and
receiving a response PPDU comprising a lightweight (LW) acknowledgement (ACK) from the device.
12. The non-transitory computer-readable medium of claim 11, wherein the operations
further comprise:
generating a mapping based on a sequence identifier for each of the plurality of MPDUs and an order of the plurality of MPDUs of the A-MPDU.
13. The non-transitory computer-readable medium of claim 12, wherein the operations
further comprise:
processing, by a PHY component, the LW ACK of the response PPDU.
14. The non-transitory computer-readable medium of claim 13, wherein processing the
LW ACK further comprises:
determining a bitmap from the LW ACK;

generating an ACK report based on the bitmap; and
determining a status of each of the plurality of MPDUs based on the ACK report and the mapping.
15. The non-transitory computer-readable medium of claim 11, wherein the PPDIJ comprises an indication that an immediate LW ACK is requested.
16. The non-transitory computer-readable medium of claim 15, wherein the indication is a trigger type specified in a subfield of a media access control (MAC) header of the A-MPDU.
17. The non-transitory computer-readable medium of any one of claims 11-16, wherein the LW ACK is stored in the LW-ACK field of the response PPDU.
18. A method comprising:
generating an aggregate media access control protocol data unit (A-MPDU) comprising a plurality of media access control protocol data units (MPDUs);
causing to send a physical layer (PHY) protocol data unit (PPDU) comprising the A-MPDU to a device; and
receiving a response PPDU comprising a lightweight (LW) acknowledgement (ACK) from the device.
19. The method of claim 18, further comprising:
generating a mapping based on a sequence identifier for each of the plurality of MPDUs and an order of the plurality of MPDUs of the A-MPDU.
20. The method of claim 19, further comprising:
processing, by a PHY component, the LW ACK of the response PPDU.
21. The method of claim 20, wherein processing the LW ACK further comprises:
determining a bitmap from the LW ACK; and
generating an ACK report based on the bitmap.

22. The method of claim 21, further comprising:
determining a status of each of the plurality of MPDUs based on the ACK report and the mapping.
23. The method of claim 19, wherein a media access control (MAC) component generates the mapping.
24. The method of claim 18, wherein the LW ACK is stored to the LW-ACK field of the response PPDU.
25. The method of any one of claims 18-24, further comprising:
receiving, from the first device, a trigger frame with an indication that the device will respond with the LW ACK.
