Abstract:
1. In a device comprising a wireless interface, a method comprising: storing a plurality of sub-frames in a memory of the device, each sub-frame comprising a media access control service data unit (MSDU) as a component and a sub-frame header as a component, wherein the sub-frame header and the MSDU for each sub-frame are stored in separate locations of the memory; and generating a media access control protocol data unit (MPDU) for wireless transmission by sequentially transferring at least the MSDU and the sub-frame header of each of the plurality of sub-frames from the memory for aggregation in the MPDU using a plurality of queued MSDU descriptors, each queued MSDU descriptor providing a first direct memory access (DMA) descriptor identifying a memory location of the corresponding sub-frame header and for a second DMA descriptor identifying an indicator of a memory location of the corresponding MSDU.
