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 for determining a number of symbols in a data field of a physical layer (PHY) protocol data unit (PPDU) is described. The method includes determining, by a wireless transmitting device, whether aggregation is to be applied to the PPDU; determining, by the wireless transmitting device, whether a PSDU length indication of the data field for the PPDU is greater than zero; selecting, by the wireless transmitting device, a first value in response to determining that (1) aggregation is not to be applied to the PPDU and (2) the PSDU length indication for the PPDU is greater than zero; and calculating, by the wireless transmitting device, the number of symbols in the data field of the PPDU based on the first value, wherein the first value is the PSDU length indication, wherein the first value is provided in a transmission vector (TXVECTOR).

Abstract: A method for determining a number of symbols in a data field of a physical layer (PHY) protocol data unit (PPDU) is described. The method includes determining, by a wireless transmitting device, whether an aggregation subfield of a signal field of the PPDU is to be set to 1 and responsive to determining that the aggregation subfield of the signal field of the PPDU is not to be set to 1, calculating, by the wireless transmitting device, the number of symbols in the data field of the PPDU based on a PHY service data unit (PSDU) length value, wherein the PSDU length value is provided in a transmission vector (TXVECTOR) and the TXVECTOR also includes an aggregated media access control (MAC) protocol data unit pre-end-of-frame padding (APEP) length value of the PPDU.
