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.

A method for encoding a bitstream is described. The method includes receiving, by an error correction unit, the bitstream; performing, by the error correction unit, encoding on the bitstream to generate an encoded bit stream that includes the bitstream and parity bits; processing, by a constellation unit, the encoded bitstream to generate constellation points in one or more encoded streams; determining, by a low-density parity-check (LDPC) tone mapper, a distance between subcarriers in an Orthogonal Frequency Division Multiplexing (OFDM) symbol of the frame; and performing, by the LDPC tone mapper, LDPC tone mapping based on the one or more encoded streams and on the determined distance to generate a permuted stream of complex numbers, wherein the distance between subcarriers is determined to be either (1) 18 for a first resource unit size used in the frame and (2) 20 for a second resource unit size used in the frame.

A wireless device determines a Basic Service Set (BSS) associated with a wireless transmitter by receiving a first frame, determining an address of the first frame, receiving a second frame, and determining, using the address of the first frame, a property of the second frame. Determining the property of the second frame may include determining whether the second frame is intra-BSS frame or an inter-BSS frame. Determining the property of the second frame may be performed by comparing an address of the second frame with the address of the first frame, and the second frame determined to be an intra-BSS frame when the address of the first frame matches the address of the second frame, and determined to be an inter-BSS frame otherwise. The address of the first frame may be a transmitter address (TA).
