Claim of US Patent No. 10,798,712

1. An apparatus of a Next Generation Vehicle-to-Everything (NGV) station (STA), the apparatus comprising: memory, and processing circuitry, configured to:encode a physical layer convergence procedure (PLCP) protocol data unit (PPDU) for transmission in a dedicated short-range communication (DSRC) frequency band allocated for vehicular communication by NGV STAs and legacy STAs,
wherein if the PPDU is to include traffic for an NGV service offered by the NGV STA, the processing circuitry is configured to:
encode the PPDU in accordance with an NGV enhanced physical (PHY) layer protocol,
wherein if the processing circuitry encodes the PPDU in accordance with the NGV enhanced PHY layer protocol, the PPDU is encoded to include a mid-amble, space-time block coding (STBC), or low-density parity check (LDPC) coding,
wherein if the PPDU is to include a basic safety message (BSM), the processing circuitry is configured to:
encode the PPDU in accordance with a legacy PHY layer protocol that is compatible with the legacy STAs,
wherein if the processing circuitry encodes the PPDU in accordance with the legacy PHY layer protocol, the mid-amble, the STBC, and the LDCP coding are excluded from the PPDU,
wherein the memory is configured to store at least a portion of the PPDU.
