Multi-user duplicate transmission

A wireless communication device comprising:

• one or more modems;
• one or more processors communicatively coupled with the one or more modems;
• and
• one or more memories communicatively coupled with the one or more processors and storing processor-readable code that, when executed by the one or more processors in conjunction with the one or more modems, cause the wireless communication device to:
• generate a physical layer (PHY) convergence protocol (PLCP) protocol data unit (PPDU) that includes first user data intended for a first user and second user data intended for a second user, the PPDU carrying bandwidth split information indicating a first bandwidth allocated for the first user data and a second bandwidth allocated for the second user data and further carrying duplicate transmission information indicating that the first bandwidth is associated with a duplicate transmission;
• apply a phase rotation to the first user data;
• map the first user data to a number (N) of tones spanning a first portion of the first bandwidth in accordance with a dual carrier modulation (DCM) scheme and based at least in part on applying of the phase rotation;
• and
• transmit the PPDU over a wireless channel spanning the first bandwidth and the second bandwidth.

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

• generating a first physical layer (PHY) convergence protocol (PLCP) protocol data unit (PPDU) that includes first user data intended for a first user, the first PPDU carrying bandwidth information indicating a first bandwidth allocated for the first user data and further carrying first duplicate transmission information indicating that the first bandwidth is associated with a duplicate transmission;
• applying a phase rotation to the first user data;
• mapping the first user data to a number (N) of tones spanning a first portion of the first bandwidth in accordance with a dual carrier modulation (DCM) scheme and based at least in part on applying of the phase rotation to the first user data;
• and
• transmitting an aggregated PPDU (A-PPDU), including the first PPDU and a second PPDU, over a wireless channel spanning the first bandwidth and a second bandwidth associated with the second PPDU.
