“…Realistically, each of the two simulation types has different objectives, which are met by them independently. The simulators are developed along with the standard-compliant Evolved Universal Terrestrial Radio Access (E-UTRA) / Long Term Evolution (LTE) 3rd Generation Partnership (3GPP) release-14 Sidelink radio technology and its integration into 5G network infrastructures [2]. Also, sidelink is known as PC5, which can facilitate the direct communication between the two ends of a C-V2X communication link.…”

At the time of the development, standardization, and further improvement are vital to the modern cellular systems such as the next generation wireless communication (5G).Simulations are essential to test and optimize algorithms and procedures prior to their implementation process of the equipment manufactures. In order to evaluate system performance at different levels, accurate simulations of simple setups, as well as simulations of more complex systems via abstracted models are necessary. In this work, two new simulators for the sidelink Cooperative-Vehicle-to-Everything (C-V2X) communication have been implemented and carried out on both the physical layer (Link-Level (LL)) and network layer (System-Level (SL)). Detailed methodologies of the LL and SL simulators for C-V2X communication have been illustrated. In the LL simulator, we get the mapping curves of BLER and Signal-to-Noise-Ratio (SNR), which are used as a baseline for measuring the performance of the LL simulation. In addition, these mapping curves are used as the important Link-to-System (L2S) interfaces. The SL simulator is utilized for measuring the performance of cell networking and simulating large networks comprising of multiple eNBs and UEs. Finally, the simulation results of both simulators for C-V2X communication are presented, which shows that different objectives can be met by using LL or SL simulations types.Index Terms-5G, Sidelink, Link-level simulator, System-level simulator This communication is a point-to-multipoint communication where several Receivers (Rxs) try to receive the same data packets transmitted from a single Transmitter (Tx). As shown in Fig.1, a network-assisted DC-V2X transmission model is implemented in this work, using a highway scenario for data packets transmission, where all UEs are connected to Base Stations (BSs). What's moreover, the UE radio architecture consisting of the U-Plane and C-Plane is provided for C-V2X communication [6]. In this work, the Tx directly transmits its data packets to the surrounding Rxs in the communication range of the Tx in the U-Plane. This method of DC-V2X communication results in lower latencies, as it does not involve the C-Plane. And all UEs are connected to the operator network in the C-Plane where can provide network control for the DC-V2X communication [7]. In 3GPP, there are two sidelink transmission modes to assign radio resources to C-V2X Txs. They are as follows:

“…The direct C-V2X communication through sidelink is a mode of communication whereby a User Entity (UE) can directly communicate with other UEs in its proximity over the PC5 air interface proposed in 3GPP [5]. This communication is a point-to-multipoint communication where several Rxs try to receive the same data packets transmitted from the Tx.…”

“…In order to support C-V2X communication, 5G should be able to provide a solution to support the high-reliability and high-availability, in the field of latency, Packet Reception Ratio (PRR) and other QoS parameters [4]. A lot of researches proposed direct C-V2X communication [3][4] [5], which means data packets are transmitted directly from the Transmitter (Tx) to the Receivers (Rxs) without going through the network infrastructures. Since no network infrastructures involved there is lower system transmission delay thereby leading to a better system performance.…”

“…For example, the IEEE 802.11p protocol has been proposed by the European Telecommunication Standards Institute (ETSI) Intelligent Transport Systems (ITS), which acts as the air interface for the direct C-V2X communication. But since there is no central entity (e.g., Base Station (BS)), packets transmission collision problem cannot be avoided [5]. Moreover, in 3GPP, PC5 has been proposed to facilitate the direct C-V2X communication which is usually referred to as the sidelink [6].…”

In recent decades, both the industry and the academy society are sparing no efforts to develop and standardize the Cellular-Vehicle-to-Everything (C-V2X) communication which is one of the prominent emerging services of the next generation of wireless network (5G). C-V2X communication is used for information exchange among the traffic participants with network-assisted which can reduce traffic accidents and improve traffic efficiency. And it is also the primary enabler for cooperative driving. But C-V2X communication has to meet different Quality of Service (QoS) requirements (e.g., ultra-high reliability (99.999%) and ultra-low latency).Index Terms-C-V2X, 5G cellular network, channel propagation models U-Plane. Therefore, without involving the C-Plane, the direct C-V2X communication is efficient from the latency aspect. And all UEs are connected to the operator network in the Cplane where can provide network control for the direct C-V2X

“…In the current literature, various kinds of resource allocation schemes have been proposed to improve the reliability and delay performance of LTE-V systems [5]. For instance, in [6], [7] and [8], the wireless link level performance improvement using spectrum sharing, adaptive link assignment and power adjustment are reported respectively. In addition, the path loss, shadow fading and delay spread of the V2V channels have been analyzed in [9].…”

Autonomous driving is usually recognized as a promising technology to replace human drivers in the near future. To guarantee the safety performance in the daily life scenario, multiple-car intelligence with high quality inter-vehicle communication capability is necessary in general. In this paper, to figure out the potential practical issues in the vehicle-to-vehicle transmission, we present a software defined radio platform for V2V communication using universal software radio peripheral (USRP). Based on the LTE framework, we modify the frame structure, the signal processing mechanisms and the resource allocation schemes to emulate the updated LTE-V standard and generate the corresponding numerical results based on the real measured signals. As shown through some empirical studies, one to four dB back-off is in general required to guarantee the reliability performance for V2V communication environments.Index Terms-V2V communication, software defined radio, LTE-V, USRP.
