摘要：A method of providing aggregated MAC protocol data unit (AMPDU) duration

control in a wireless communication device includes setting an AMPDU duration. Pass/failstatistics are collected for each MPDU of an AMPDU in a time window, W. A packet errorrate (PER) difference is calculated between first and last sets of MPDUs for each AMPDUin the window. An average PER difference is calculated across all AMPDUs in the window.When the average PER difference is greater than a first threshold, then the AMPDUduration is decreased. When the difference is less than a second threshold, then theAMPDU duration is increased. When the difference is within the first and the secondthresholds, then the method returns to the step of collecting for a next time window.The AMPDU duration can also be adjusted based on detected Doppler and line-of-sighttransmissions.
