Single acknowledgment policy for aggregate MPDU

A method for acknowledging data units in a wireless local area network, the method comprising:

• receiving, at a first communication device and from a second communication device, an aggregate medium access control (MAC) protocol data unit (A-MPDU) that includes multiple data units, wherein the multiple data units include i) a trigger frame, and ii) a non-trigger frame having an acknowledgment policy and corresponding to a single acknowledgment frame that acknowledges the non-trigger frame but does not include an identification of the non-trigger frame, wherein the trigger frame includes an indication of radio resources allocated for the single acknowledgment frame;
• generating, at the first communication device, the single acknowledgment frame to acknowledge receipt of the non-trigger frame;
• causing the single acknowledgment frame to be transmitted from the first communication device to the second communication device via the allocated radio resources;
• and
• prior to receiving the A-MPDU, transmitting an announcement indicating the first communication device supports an acknowledgement enabled single-traffic class aggregate MPDU and supports an acknowledgment enabled, multi-traffic class aggregate MPDU,
• wherein the A-MPDU further includes a frame having a block acknowledgement policy and the A-MPDU forms an acknowledgment enabled, multi-traffic class A-MPDU.

A wireless communication device, comprising:

• a wireless network interface device associated with a first communication device, the wireless network interface device comprising one or more integrated circuit (IC) devices configured to:
• generate a plurality of medium access control (MAC) protocol data units (MPDUs) of an aggregate MPDU intended for a second communication device, wherein the plurality of MPDUs includes i) a trigger frame, and ii) a non-trigger frame having an acknowledgment policy and corresponding to a single acknowledgment frame that acknowledges the non-trigger frame but does not include an identification of the non-trigger frame, and wherein the trigger frame includes an indication of radio resources allocated for the single acknowledgment frame to the non-trigger frame,
• generate the aggregate MPDU to include the plurality of MPDUs;
• control the wireless network interface device to transmit the aggregate MPDU to the second communication device;
• and
• prior to generating the plurality of MPDUs, receive an announcement indicating the second communication device supports an acknowledgement enabled single-traffic class aggregate MPDU and supports an acknowledgment enabled, multi-traffic class aggregate MPDU,
• wherein the plurality of MPDUs further includes a frame having a block acknowledgement policy and the plurality of MPDUs form an acknowledgment enabled, multi-traffic class aggregate MPDU.
