Methods, systems, and devices for wireless communications are described. In one example, a method includes receiving broadcast information from a base station that identifies types of resources for vehicle-based sidelink communications that are supported by the base station and transmitting a request to the base station for resource scheduling information to perform a vehicle-based sidelink communication based on the broadcast information. In some cases, the request includes an indication of a type of resources for the vehicle-based sidelink communication supported by the base station and a quality of service (QoS) metric associated with the vehicle-based sidelink communication. In some cases, the method further includes receiving, in response to the request, a response from the base station that comprises the resource scheduling information to perform the vehicle-based sidelink communication.
