Enhanced vehicle-to-everything radio access technology migration

An apparatus for wireless communications at a user equipment (UE), comprising:

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• select, at the UE that is configured to transmit a message to a neighboring UE via multiple protocols, one or more parameters indicative of a radio access technology (RAT) to be used for the message;
• convey information indicating the one or more parameters from a first layer of the UE to a second layer of the UE, wherein the first layer is an upper layer with respect to the second layer;
• and
• instantiate, by the second layer and based at least in part on the one or more parameters, a channel for communications with the neighboring UE according to the RAT.

An apparatus for wireless communications at a user equipment (UE), comprising:

• means for identifying, at the UE that is configured to transmit a message to a neighboring UE via multiple formats, a service parameter indicative of a format to be used for the message;
• means for conveying information indicating the service parameter from a first layer of the UE to a second layer of the UE, wherein the first layer is an upper layer with respect to the second layer;
• and
• means for generating, by the second layer and based at least in part on the information, the message in the format for communicating with the neighboring UE.

• generating, by the second layer and based at least in part on the information indicating the service parameter indicative of the format to be used for the message to the neighboring user equipment, the message in the format;
• and
• transmitting the message to the neighboring user equipment.
