1. A method for simultaneously transmitting in a plurality of frequency segments, comprising:
generating, at a communication device, a first packet for transmission in a first frequency segment, including generating a first physical layer (PHY) preamble of the first packet to include:
a first legacy signal field (L-SIG) having first duration information that indicates a first duration of the first packet, and
first non-legacy signal field information having first modulation information that indicates a first modulation used in the first packet;
generating, at the communication device, a second packet for transmission in a second frequency segment, including generating a second PHY preamble of the second packet to include:
a second L-SIG having second duration information that indicates a second duration of the second packet, wherein the second duration is different than the first duration, and
second non-legacy signal field information having second modulation information that indicates a second modulation used in the second packet, wherein the second modulation is different than the first modulation; and
simultaneously transmitting, by the communication device, the first packet in the first frequency segment and the second packet in the second frequency segment.
