    Hi experts,

    I?m preparing my CWAP exam. In CWAP book, there is a statement about BA, that is ?When a station intends to use the Block ACK mechanism to transmit QoS data, it first checks to see whether the peer station is capable of performing the Block ACK mechanism.?

    However, I?m confused how a STA gets to know if the peer STA is able to support BA.

    Which IE or field indicate that? Or need an exchange of special action frames?

    Thanks
    Tao
