Block coding scheme for phy data unit transmission

A communication device comprising:

• a network interface device having one or more integrated circuits configured to:
• receive a plurality of information bits to be included in the PHY data unit,
• determine a maximum number of information bits that can be encoded such that, after the plurality of information bits have been encoded using i) a forward error correction scheme to obtain coded information bits, and ii) a block coding scheme to obtain block coded bits from the coded information bits, the block coded bits fit within a single orthogonal frequency division multiplex (OFDM) symbol on the communication channel, wherein
• the maximum number of information bits is based on a number of repetitions of the coded information bits by the block coding scheme, and
• a number of the block coded bits for the maximum number of information bits is less than a number of data tones of the single OFDM symbol,
• encode the plurality of information bits with the maximum number of information bits using the forward error correction scheme and the block coding scheme to generate the block coded bits, and
• generate the PHY data unit to include the block coded bits in the single OFDM symbol.

• receiving, by the communication device, a plurality of information bits to be included in the PHY data unit;
• determining, by the communication device, a maximum number of information bits that can be encoded such that, after the plurality of information bits have been encoded using i) a forward error correction scheme to obtain coded information bits, ii) a block coding scheme to obtain block coded bits from the coded information bits with a base number of repetitions, and iii) a puncturing scheme to obtain punctured bits from the block coded bits, the punctured bits fit within a single orthogonal frequency division multiplex (OFDM) symbol on the communication channel, wherein
• the maximum number of information bits is based on a number of repetitions of the coded information bits by the block coding scheme, and
• at least some of the plurality of information bits corresponding to the punctured bits have a different number of repetitions;
