Abstract: A dynamic A-MSDU enabling method is disclosed. The method enables the recipient of an aggregate MAC service data unit (A-MSDU) under a block ACK agreement to reject the A-MSDU. The method thus distinguishes between A-MSDU outside of the block ACK agreement, which is mandatory, from A-MSDU under the block ACK agreement, which is optional. The method thus complies with the IEEE 802.11n specification while enabling the recipient to intelligently allocate memory during block ACK operations.

Abstract: Memory associated with a mobile communication device, such as memory removably inserted into a memory card slot, may be accessed, in the alternative, by a mobile communication platform or by a remote USB host. A memory access module connected to the memory card slots is operative in one of two modes: a pass-through mode and a USB mode. In the pass-through mode, the memory card slots are directly connected, via switching circuits, to memory interfaces on the mobile communication platform. A USB interface on the mobile communication platform may additionally be connected, in pass-through mode, via a USB hub to a remote USB host. In the USB mode, the memory card slots are connected, via switching circuits, second memory interfaces, and a controller, to a USB hub supporting USB 3.0 transfer protocols, and accessible by a remote host.

Abstract: Parallel data generated by demultiplexing received serial data such as in a Serial RapidIO (SRIO) data stream can become misaligned as a result of, e.g., clock tolerance compensation (CTC) processing at the receiver. In one embodiment of the invention, the misaligned parallel data is properly aligned based on a mapping from each of a finite number of possible previous alignment conditions (e.g., words A-D) to a corresponding finite number of possible subsequent alignment conditions (e.g., words B-G). The change from a previous alignment condition to a different subsequent alignment condition is recognized by determining the location of start-of-packet (SOP) or start-of-control-symbol (SOC) data in the parallel data stream.
