Advanced vehicle-to-everything (V2X) safety applications must operate with ultra-low latency and be highly reliable. Therefore, they require sophisticated supporting technologies. This is especially true for cooperative applications, such as Collective Perception (CP), where a large amount of data constantly flows among vehicles and between vehicles and a network intelligence server. Both low and high-level support is needed for such an operation, meaning that various access technologies and other architectural elements also need to incorporate features enabling the effective use of V2X applications with strict requirements. The new 5G core architecture promises even more supporting technologies, like Multi-access Edge Computing (MEC). To test the performance of these technologies, an integrated framework for V2X simulations with 5G network elements is proposed in the form of combining Simu5G, a standalone 5G implementation, with the go-to V2X-simulator, Artery. As a first step toward a fully functional MEC-assisted CP Service, an extension to Simu5G’s edge implementation is introduced. The edge application is responsible for dispatching the Collective Perception Messages generated by the vehicles via the 5G connectivity so that a MEC server provided by the network can process incoming data. Simulation results prove the operability of the proposed integrated system and edge computing’s potential in assisting V2X scenarios.

“…Various aspects of IEEE 802.11bd networks are studied in many papers [28], [37], [43]- [51]. Paper [43] The authors of [37], [46]- [48] compare the performance of IEEE 802.11p and IEEE 802.11bd. The results show that adaptive blind retransmissions of broadcast frames and the MCS with DCM can highly enlarge the maximum transmission range of NGV STAs and improve their PLR compared with non-NGV STAs.…”

A Study of Channel Bonding in IEEE 802.11bd Networks

In recent years, Vehicle-To-Everything (V2X) applications have been actively developing, and the Quality of Service (QoS) requirements are becoming more stringent. To support V2X applications, IEEE developed the IEEE 802.11p standard in 2010. However, systems based on this standard fail to fulfill requirements on very low frame transmission delay and packet loss ratio imposed by modern V2X applications, such as applications for autonomous driving and platooning. To satisfy new requirements, IEEE has launched a new IEEE 802.11bd project to design the next generation of IEEE 802.11p. An important feature of IEEE 802.11bd is the channel bonding technique, which allows transmitting data in two adjacent channels simultaneously. Thus, it increases data rates and may reduce delays and packet loss ratio. The current version of IEEE 802.11bd specifies two channel bonding techniques, which differ from that used in modern Wi-Fi networks. This work evaluates the performance of the three aforementioned techniques from the IEEE 802.11 family of standards considering frame transmission delays and packet loss ratio. With rigorous simulations, it is shown that, in most cases, the channel bonding techniques highly decrease the percentage of both IEEE 802.11bd and legacy stations with unsatisfied QoS requirements on delays and packet loss ratio. Unfortunately, sometimes, the IEEE 802.11bd channel bonding techniques significantly worsen performance. Moreover, the work highlights that the choice of the primary channel for channel bonding techniques significantly affects the network performance. As a result, the paper provides a recommendation for selecting both the most suitable channel access method and primary channel.

“…However, the piggyback method makes the packet latency increased. A packet repetition method was proposed in IEEE 802.11bd standard and its performance is degraded due to an increased packet transmission time [9]. And other schemes such as the channel estimation algorithm or diversity techniques at the receiver have been studied to improve the PER [10, 11].…”

A Vehicle to Anything (V2X) packet data is used for a vehicle safety and automated driving applications. It is broadcasted periodically to provide a warning message or share the vehicular sensor's data among vehicles. This paper proposes IEEE 802.11p based dual channel transmission and packet selection method to improve the Packet Detection Rate (PDR) for V2X broadcasting messages. The PDR gain of the proposed scheme over the single channel transmission is given theoretically by the packet error rate of a single radio channel.
