To implement this feature, the train of MPDUs must not be handled as a single compound (as generated by the aggregation FU wifimac::draftN::Aggregation) and thus as a single event on the channel, but as multiple events with their own SINR and error statistic. Hence, the compound must be broken into fragments, one for each MPDU, before the transmission, and re-assembled, if it was received error-free. This is the task of the wifimac::draftN::DeAggregation FU, which should be placed below the wifimac::lowerMAC and above the wifimac::convergence::ErrorModel and CRC.
Of course, the FU has to "translate" the onTxStart/onTxEnd of the fragments into one onTxStart/onTxEnd for the whole frame - hence it is both subject and observer for the wifimac::convergence::ITxStartEnd.
