    Abstract: For a first group of devices having a first group size, a set of block allocations is selected from a codebook. A block allocation for the first group of devices is selected from the selected set of block allocations. A corresponding integer number of different orthogonal frequency division multiplexing (OFDM) tone blocks is assigned to each device of the first group of devices according to the allocation. An orthogonal frequency division multiple access (OFDMA) data unit to be transmitted to the first group of devices via the WLAN communication channel is generated using the assigned set of OFDM tone blocks. The OFDMA data unit includes a preamble portion and a data portion, the preamble portion having an index to the codebook that indicates i) the first group size, and ii) the selected block allocation.

    Abstract: Methods, software, circuits and systems involving a low complexity, tailbiting decoder. In various embodiments, the method relates to concatenating an initial and/or terminal subblock of the serial data block and outputting decoded data from an internal block of the modified data block. The circuitry generally includes a buffer, logic configured to concatenate an initial and/or terminal subblock to the serial data block, and a decoder configured to decode the data block, estimate starting and ending states for the data block, and output an internal portion of the serial data block and the one or more sequences as decoded data. The invention advantageously reduces the complexity of a suboptimal convolutional decoder, ensures smooth transitions at the beginning and end of the serial data block during decoding, and increases the reliability of the starting and ending states, without adding overhead to the transmitted data block.
