Claim of US Patent No. 9,125,235

1. A method, comprising:
obtaining data for transmission to a wireless communication device, wherein the wireless communication device is configured
to process incoming transmissions based on an aggregate data unit format that specifies signaling for aggregating multiple
medium access control (MAC) protocol data units (MPDUs);

generating, based on the data and the aggregate data unit format, an aggregate MPDU (A-MPDU) that comprises a single MPDU
having a length greater than zero, the single MPDU residing in a subframe of the A-MPDU;

setting a delimiter of the subframe to indicate that the single MPDU is the only MPDU within the A-MPDU that has a length
greater than zero, and to cause the wireless communication device to accept the A-MPDU without a corresponding block acknowledgement

including, in a physical (PHY) frame, the A-MPDU; and
transmitting the PHY frame to the wireless communication device.
