A device, method, and non-transitory computer-readable medium are provided for communicating using an integrated millimeter wave (IMMW) physical layer convergence protocol data unit (PPDU). Access point circuitry may generate a preamble for IMMW PPDU, including at least a Short Training Field (STF), a Long Training Field (LTF), and a SIG field, wherein the payload content of the SIG field is duplicated at least three times in the frequency domain to occupy a 320 MHz channel, and wherein the SIG field includes pilot signals and modulated signals of encoded SIG payload content; generate a data field for the IMMW PPDU including at least data orthogonal frequency division multiplex (OFDM) symbols, wherein each OFDM symbol includes data subcarriers and pilot subcarriers; and send the IMMW PPDU to one or more station devices (STAs).
