Abstract: A method for encoding a bitstream for a frame in a wireless transmission is described. The method includes receiving, by an error correction unit of the wireless device, the bitstream; performing, by the error correction unit, forward error correction on the bitstream to generate an error corrected bitstream; determining, by a dual sub-carrier modulation (DCM) mapper of the first wireless device, a number of data subcarriers for modulating the error corrected bitstream to subcarriers in each half of an orthogonal frequency-division multiplexing (OFDM) symbol, wherein the number of data subcarriers is determined to be (1) 26 for a first bandwidth of the frame, (2) 54 for a second bandwidth and performing, by the DCM mapper, DCM on the error corrected bitstream based on the determined number of data subcarriers to generate a stream of complex numbers corresponding to the number of data subcarriers.

Abstract: A method is performed by a wireless device. The method comprises receiving a predetermined number N of Orthogonal Frequency Division Multiplexing (OFDM) symbols of a PHY Protocol Data Unit (PPDU), determining, using the Nth received OFDM symbol, whether the PPDU is a PPDU according to a first wireless network standard or a PPDU according to a second wireless network standard, and decoding the PPDU according to the determined wireless network standard. The predetermined number N corresponds to either a location of a Legacy Signal (L-SIG) field in the PPDU or the location of a symbol of a second field of the second wireless network standard in the PPDU, the second field being different from the L-SIG field. The first and second wireless network standards may each be a Vehicle to Everything standard or an Intelligent Transportation System standard, and may be different from each other.
