Assignee: APPLE INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. An apparatus, comprising:
a memory; and
processing circuitry in communication with the memory, wherein the processing circuitry is configured to:
decode, from an initiating user equipment device (UE), control signaling that indicates a proposed PC5 radio access technology (RAT) for a vehicle-to-everything (V2X) service, wherein the proposed PC5 RAT is either a Long Term Evolution (LTE) PC5 RAT or a New Radio (NR) PC5 RAT and one or more PC5 RATs supported by the initiating UE; and
select one of the LTE PC5 RAT or the NR PC5 RAT for the V2X service, wherein if the proposed PC5 RAT is supported, the proposed PC5 RAT is selected, and wherein if the proposed PC 5 RAT is not supported, if at least one of the PC5 RATs is supported by the initiating UE and the apparatus, select the PC5 RAT that is supported by both the initiating UE and the apparatus;
encode, from transmission to the initiating UE, a PC5 RAT response message that indicates which PC5 RAT, of the LTE PC5 RAT and the NR PC5 RAT, was selected for the V2X service; and
decode, from the initiating UE, a PC5 RAT acknowledgement (ACK) message to indicate reception of the PC5 RAT response message.
