IEEE 802.11ax utilizes frame aggregation and compressed block acknowledgements to reduce the MAC overhead and to increase the goodput. We analyze IEEE 802.11ax frame aggregation in error-prone environments and propose to adaptively limit the MPDU size. This results in MAC frames that are still small enough to have a high transmission success rate. A performance study using the discrete-event simulator ns-3 illustrates the benefits of the proposed approach. We find that a high retransmission rate results in a low utilization of the acknowledgment window and discuss its major negative impact on the goodput. Our delay-related studies further show that MAC mechanisms like strict ordering contribute disproportionally to increased latency due to head-of-line blocking, especially under high error rate conditions. We conclude that for decreased delays, smaller MPDUs are beneficial.
