Abstract
At least a portion of a physical layer (PHY) preamble of a PHY protocol data unit (PPDU) for transmission in a vehicular communication network is generated to span a first bandwidth a) based on a first orthogonal frequency division multiplexing (OFDM) numerology that is defined for a second bandwidth greater than the first bandwidth and b) down-clocked to generate the at least the portion to span the first bandwidth. The at least the portion includes a legacy portion decodable by a legacy device operating in the network. A data portion is generated based on a second OFDM numerology defined to span the second bandwidth. The PPDU is generated to include the at least the legacy portion of the PHY preamble in a first sub-band, a duplicate of the at least the portion of the preamble in a second sub-band, and the data portion that spans the second bandwidth.
