    Ok here goes without the pretty arrows:

    STA sends ADDBA Request to AP

    AP sends ACK to STA

    AP sends ADDBA Response to STA


    STA sends Ack to AP
    STA sends QoS Data to AP
    STA sends QoS Data to AP
    STA sends QoS Data to AP
    STA sends BlockAckReq to AP


    AP sends BlockAck to STA -Some frames sent from STA to AP was not received as indicated in the Bit map field of the BlockAck


    STA resends QoS Data to AP
    STA resends QoS Data to AP


    AP sends BlockAck to STA


    STA sends DELBA Request to AP (request to end the session)


    AP sends Ack to STA


    I haven't found supporting documentation of this, but it is the only situation I can think of currently that would allow for a BlockAck to be sent not in immediate response to a BlockAckReq.

    Thoughts?
