Abstract:
1. A method for generating a physical layer (PHY) data unit for transmission via a communication channel, the method comprising: receiving a plurality of information bits to be included in the PHY data unit; determining a number of orthogonal frequency division multiplexing (OFDM) symbols that are needed to transmit the plurality of information bits after encoding with a low density parity check (LDPC) encoder; performing one or more of a, b, c, d, e, and f according to a set of rules so that a receiving device can determine a number of information bits in the PHY data unit based on i) an indication of the number of OFDM symbols, and ii) the set rules: encoding the plurality of information bits using the LDPC encoder; and generating the PHY data unit i) to include the LDPC encoded information bits in OFDM symbols and ii) to include an indication of the number of OFDM symbols in the PHY data unit, wherein performing one or more of a, b, c, d, e, and f according to the set of rules comprises:
