Methods and Apparatus for Generation of Physical Layer Protocol Data Units for Vehicular Environments

A method for wireless communication, the method comprising:

• selecting, at a communication device, a frequency bandwidth via which a physical layer (PHY) protocol data unit (PPDU) will be transmitted in a vehicular communication network, wherein the frequency bandwidth is selected from a set of permissible frequency bandwidths;
• selecting, at a communication device, a downclocking ratio for generating the PPDU to span the selected frequency bandwidth, wherein the downclocking ratio is selected based on the selected frequency bandwidth;
• generating, at a communication device, the PPDU i) according to the selected downclocking ratio, and ii) based on an orthogonal frequency division multiplexing (OFDM) numerology defined by one of a) the IEEE 802.11n Standard, b) the IEEE 802.11ac Standard, and c) the IEEE 802.11ax Standard, wherein the PPDU is generated to span the selected frequency bandwidth;
• and
• transmitting, by the communication device, the PPDU in the vehicular communication network.
