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.

Abstract: A method is described for generating and transmitting a frame by a station. The method includes generating a frame that includes a signaling field and a data field, wherein the signaling field includes a midamble indication that indicates a midamble periodicity used in the data field of the frame and wirelessly transmitting the frame to a recipient.

Abstract: A method is described, which includes receiving, by a wireless station from a first access point, an overlapping basic service set (OBSS) status report request, which requests information from the station regarding a set of neighboring access points; transmitting, by the wireless station to the first access point, an OBSS status report that indicates path-loss characteristics of channels between the set of neighboring access points and the wireless station; receiving, by the wireless station from the first access point, an access point cooperation null data packet announcement frame, which indicates a cooperative transmission between the first access point and the second access point to the wireless station; receiving, by the wireless station from the first access point, a first null data packet and a second null data packet from the second access point, wherein the first and second null data packets are transmitted as part of the cooperative transmission.

Abstract: 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.
