Preamble design within wireless communications

A wireless communication device comprising:

• a processor configured to:
• identify a selected orthogonal frequency division multiplexing (OFDM) packet format from a first OFDM packet format, a second OFDM packet format, and a third OFDM packet format;
• generate, based on the selected OFDM packet format, an OFDM packet that includes a preamble, wherein the preamble includes a short training field (STF) that is adjacently followed by a long training field (LTF) that is adjacently followed a first signal field (SIG) that is adjacently followed by a copy of the first SIG that is adjacently followed a second SIG that is adjacently followed by a third SIG, wherein the STF, the LTF, and first SIG are based on a first communication protocol, wherein the second SIG and the third SIG are based on a second communication protocol, wherein the first SIG includes information that specifies modulation coding set (MCS) of at least one of the second SIG or the third SIG;
• generate the preamble, when the selected OFDM packet format is the first OFDM packet format, such that the first SIG includes first content;
• generate the preamble, when the selected OFDM packet format is the second OFDM packet format, such that the second SIG includes second content, the second SIG has a first phase, and the third SIG has a second phase that is 90 degrees phase shifted from the first phase;
• generate the preamble, when the selected OFDM packet format is the third OFDM packet format, such that the second SIG includes the second content, and both the second SIG and the third SIG have the first phase;
• and
• transmit the OFDM packet to another wireless communication device.

A method for execution by a wireless communication device, the method comprising:

• identifying a selected orthogonal frequency division multiplexing (OFDM) packet format from a first OFDM packet format, a second OFDM packet format, and a third OFDM packet format;
• generating, based on the selected OFDM packet format, an OFDM packet that includes a preamble, wherein the preamble includes a first signal field (SIG) that is followed by a second SIG that is followed by a third SIG, wherein the first SIG is based on a first communication protocol, and the second SIG and the third SIG are based on a second communication protocol;
• generating the preamble, when the selected OFDM packet format is the first OFDM packet format, such that the first SIG includes first content;
• generating the preamble, when the selected OFDM packet format is the second OFDM packet format, such that the second SIG includes second content, the second SIG has a first phase, and the third SIG has a second phase that is 90 degrees phase shifted from the first phase;
• generating the preamble, when the selected OFDM packet format is the third OFDM packet format, such that the second SIG includes the second content, and both the second SIG and the third SIG have the first phase;
• and
• transmitting, via a communication interface of the wireless communication device, the OFDM packet to another wireless communication device.
