Abstract:
A boundary within a last orthogonal frequency division multiplexing (OFDM) symbol of a PHY data unit is determined. Pre-encoder padding bits are added to a set of information bits to generate a set of padded information bits such that the set of padded information bits, after being encoded, fill one or more OFDM symbols up to the boundary within the last OFDM symbol. The set of padded information bits are encoded to generate a set of coded bits. A PHY preamble is generated to include a subfield that indicates the boundary. The one or more OFDM symbols are generated to include (i) the set of coded information bits in the one or more OFDM symbols up to the boundary to allow a receiving device to stop decoding the one or more OFDM symbols at the boundary, and (ii) post-encoder padding bits in the last OFDM symbol following the boundary.

Claim (Index 9):
An apparatus, comprising:\n a network interface device associated with a first communication device, wherein the network interface device includes one or more integrated circuit (IC) devices configured to:\n determine a number of orthogonal frequency division multiplexing (OFDM) symbols for a multi-user physical layer (PHY) data unit based on respective sets of information bits corresponding to respective second communication devices, wherein the multi-user PHY data unit is for transmission via a communication channel, \n determine a common boundary within a last OFDM symbol of the PHY data unit based on the respective sets of information bits corresponding to respective second communication devices, \n add respective numbers of pre-encoder padding bits to the respective sets of information bits corresponding to respective second communication devices to generate respective sets of padded information bits corresponding to the respective second communication devices, wherein the respective numbers of pre-encoder padding bits are determined such that the padded information bits, after being encoded, fill one or more OFDM symbols up to the common boundary within the last OFDM symbol, \n encode the respective sets of padded information bits to generate respective sets of coded bits, \n generate the one or more OFDM symbols of the PHY data unit to include (i) the respective sets of coded information bits in an initial portion of the one or more OFDM symbols up to the common boundary within the last OFDM symbol, and (ii) respective sets of post-encoder padding bits, added to the respective sets of coded bits, in a remaining portion of the last OFDM symbol following the common boundary, and \n include an indication of the common boundary in a PHY preamble of the PHY data unit to inform the second communication devices of the common boundary so that the second communication devices can stop decoding the one or more OFDM symbols after decoding the initial portion of the one or more OFDM symbols.
