Techniques are provided for supporting V2X communications which may be implemented in various apparatuses, methods, and/or articles of manufacture. In certain aspects an extended transmission profile may be determined to support V2X communications via 5G NR RATs between two or more wireless devices. For example, one or more processing units of a wireless device may determine that a NR RAT is requested for a V2X communication based, at least in part, on service information associated with data to be transmitted, determine an extended Tx Profile for the V2X communication, and initiate transmission of at least a portion of the data via the NR RAT using the transceiver based on the extended Tx Profile.
