Duplicated data sequence transmissions with reduced peak to average power ratio

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

• obtaining a first sub-physical layer convergence protocol (PLCP) protocol data unit (PPDU) from a PPDU that includes a data field with data content;
• obtaining a second sub-PPDU by duplicating the PPDU, wherein the data fields of the first and the second sub-PPDUs are valid data fields of a PPDU, and carry the same data content as the PPDU;
• applying at least one of a phase rotation, a phase offset, or a phase ramp to at least one of a first resource unit (RU)(2×996) or a second RU(2×996);
• and
• transmitting, simultaneously, the first sub-PPDU on the first RU(2×996) of a wideband channel and the second sub-PPDU on the second RU(2×996) of the wideband channel, wherein the first and second sub-PPDU comprise a duplicated packet format (DUPed) PPDU.

A wireless communication device, comprising:

• at least one processor;
• and
• at least one memory communicatively coupled with the at least one processor and storing processor-readable code that, when executed by the at least one processor, is configured to:
• obtain a first sub-physical layer convergence protocol (PLCP) protocol data unit (PPDU) from a PPDU that includes a data field with data content;
• obtain a second sub-PPDU by duplicating the PPDU including the data content of the PPDU;
• apply at least one of a phase rotation, a phase offset, or a phase ramp to at least a portion of a second set of sub-carriers;
• and
• transmit, simultaneously, the first sub-PPDU on a first set of sub-carriers of a wideband channel and the second sub-PPDU on the second set of sub-carriers of the wideband channel.

A non-transitory processor-readable medium storing executable instructions, which when executed by one or more processors, causes one or more processors to:

• obtain a first sub-physical layer convergence protocol (PLCP) protocol data unit (PPDU) from a PPDU that includes a data field with data content;
• obtain a second sub-PPDU by duplicating the PPDU including the data content of the PPDU;
• apply at least one of a phase rotation, a phase offset, or a phase ramp to at least a portion of a second set of sub-carriers;
• and
• transmit, simultaneously, the first sub-PPDU on a first set of sub-carriers of a wideband channel and the second sub-PPDU on the second set of sub-carriers of the wideband channel.
