Abstract: Techniques described herein provide for leader selection of a group of vehicles, based on inter-vehicle communications. According to embodiments, a host vehicle can determine it qualifies to be the leader of a potential group by comparing vehicle information of other cars in the potential group with its own vehicle information. Once the determination has been made, the host vehicle can then send a request to be the group leader to the other vehicles. If the other vehicles accept, the host vehicle can initiate group formation. Otherwise, another vehicle can reject the request and send its own request to become the group leader, reinitiating group leader negotiation until a group leader is determined.

Abstract: A responder user equipment (UE) in separate ranging sessions may determine whether there is a collision between the ranging signals assigned to broadcast in the separate ranging sessions. A collision in the ranging signals is detected when the ranging signals have the same frequencies and broadcast times, e.g., the broadcast time of one ranging signal is within a predetermined amount of time for the other ranging signal. When a collision in the ranging signals is detected, the responder UE sends a message to the initiator UE indicating the possibility of a collision. Available times for broadcasting the ranging signals may be determined, e.g., by the responder UE or the initiator UE. The initiator UE may initiate a new ranging session based on the available times for broadcasting the ranging signal or may proceed with the ranging session with the possibility that the responder UE will not participate.
