1. A method for generating and transmitting a physical layer (PHY) data unit for transmission via a communication channel that comprises a plurality of sub-channels, the method comprising:
generating, at a communication device, a first portion of a PHY preamble of the PHY data unit, the first portion of the PHY preamble being generated to include:
a plurality of legacy short training fields (L-STFs) spanning respective sub-channels,
a plurality of legacy long training fields (L-LTFs) spanning the respective sub-channels,
a plurality of legacy signal fields (L-SIGs) spanning the respective sub-channels, and
a plurality of first non-legacy signal fields spanning the respective sub-channels;
generating, at the communication device, a second portion of a PHY preamble of the PHY data unit, the second portion of the PHY preamble immediately following the first portion of the PHY preamble and being generated to include:
a non-legacy short training field spanning all sub-channels in the plurality of sub-channels,
a plurality of non-legacy long training fields immediately following the non-legacy short training field, each non-legacy training field spanning all sub-channels in the plurality of sub-channels, and
a second non-legacy signal field immediately following the plurality of non-legacy long training fields, the second non-legacy signal field spanning all sub-channels in the plurality of sub-channels;
generating, at the communication device, a PHY payload of the PHY data unit that immediately follows the second non-legacy signal field; and
transmitting, by the communication device, the PHY data unit via the communication channel.
