One of the challenges of direct vehicle-to-vehicle (V2V) communication is to find efficient radio resource management (RRM) strategies that can fulfil the requirements even with high traffic density. In cellular networks, a device-to-device (D2D) communication is usually split into two phases: the discovery process, for node awareness of each other; and the communication phase itself, where data exchange takes place. In the case of V2V, the discovery phase can utilize the status information that cars broadcast periodically as the beacons to detect the presence of neighbouring cars. For the delivery of specific messages (e.g., a hazardous event), direct communications can then be set up in a very fast way, based on the previously collected information. In this paper we identify key RRM challenges in direct V2V, and we focus on the design of the first phase, the discovery. Several aspects have been revealed as essential to ensure the reliability and latency requirements of said discovery, such as the autonomous selection of the resources, the duplexing mode and the interference cancellation (IC) receivers.
