Abstract: A method of providing aggregated MAC protocol data unit (AMPDU) duration control in a wireless communication device includes setting an AMPDU duration. Pass/fail statistics are collected for each MPDU of an AMPDU in a time window, W. A packet error rate (PER) difference is calculated between first and last sets of MPDUs for each AMPDU in 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 AMPDU duration is decreased. When the difference is less than a second threshold, then the AMPDU duration is increased. When the difference is within the first and the second thresholds, 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-sight transmissions.

Abstract translation: 在无线通信设备中提供聚合MAC协议数据单元（AMPDU）持续时间控制的方法包括设置AMPDU持续时间。 在时间窗口W中收集AMPDU的每个MPDU的通过/失败统计信息。在窗口中的每个AMPDU的第一组和最后一组MPDU之间计算分组错误率（PER）差异。 在窗口中的所有AMPDU之间计算平均PER差异。 当平均PER差大于第一阈值时，AMPDU持续时间减小。 当差值小于第二阈值时，AMPDU持续时间增加。 当差异在第一和第二阈值内时，该方法返回到下一个时间窗口的收集步骤。 AMPDU持续时间也可以根据检测到的多普勒和视线传输进行调整。
