Detailed Description

Test for Block Ack Policy with non-null BA threshold and TX window blocked.

An EHT device establishes a Block Ack agreement (for TID 0) with the AP and uses a Block Ack threshold of 0.125 (i.e., Block Ack is requested if there are at least 64 * 0.125 = 8 MPDUs to be acknowledged, where 64 is the Block Ack buffer size). An application installed on the non-AP node generates 70 packets, hence an A-MPDU containing the first 64 MPDUs is transmitted. The first 5 MPDUs in that A-MPDU are corrupted. We check that:

• the first A-MPDU contains MPDUs with sequence numbers from 0 to 63
• the second A-MPDU contains the 5 retransmitted MPDUs (with sequence numbers from 0 to 4) only, because the TX window is blocked
• the third A-MPDU contains the remaining 6 MPDUs (with sequence numbers from 64 to 69)
• 3 A-MPDUs and 3 BlockAck frames are transmitted during the simulation
• the MAC queue is empty at the end of simulation (meaning that all MPDUs were acknowledged)
