The global status of road safety shows that accidents will cost the world economy approximately 1.8 billion dollars. So, it has become a true global social objective where the Internet of Vehicles (IoV) comes into play, which is an advanced version of the Internet of Things (IoT) concept where the vehicles are connected so as to form an Intelligent Transportation System (ITS). IoV makes use of vehicular communications which allows vehicles to transfer date in real-time with other vehicles, Roadside Units (RSU), and pedestrians. The ITS service uses a 5.9 GHz band of spectrum and V2V communication uses a PC5 interface where the base station is not involved. Cooperative Awareness Messaging (CAM) is used to obtain vehicle status information, where the messages are broadcast periodically. According to 3GPP TS 38.211, there are a number of physical signals and channels used for transmitting data and control signals in the sidelink. These signals are mapped onto a resource grid to form the frame structure. There is a parameter called Modulation and Coding Scheme (MCS), which is varied for different values to analyze the Packet Error Rate (PER) performance of the system. The performance is also evaluated in terms of Packet Receive Ratio (PRR). PRR is defined as the ratio of the number of neighbours correctly decoding a message at a given distance and the total number of neighbours at the same distance. Based on the performance, it can be inferred that PRR decreases as the vehicle density increases with increasing distance between the vehicles. Therefore, an optimum value of vehicle density needs to be maintained for 5G V2X communication.
