A resource manager stores a mapping of transmission slots for each of the zones. When a vehicle enters one of the zones, the resource manager performs a slot assignment for the vehicle from the periodic transmission slots allocated to the zone, and transmits a notification to the vehicle indicating the slot assignment.
