“…However, the IEEE 802.11bd channel bonding techniques have not been well investigated in the literature. To the best of our knowledge, only two papers study IEEE 802.11bd channel bonding techniques, namely [28], [52]. However, a substantial drawback of [28] is that the authors compare the channel bonding techniques only in terms of frame transmission delays neglecting the PLR, although V2X applications impose QoS requirements on both transmission delays and the PLR, and the PLR also has a significant impact on the performance.…”

“…However, the paper has two noticeable disadvantages. First, [52] does not take into account the impact of NGV STAs on non-NGV STAs, al-though the requirement that NGV STAs shall not degrade the performance of non-NGV STAs is vital. Second, it considers only a scenario with the same number of vehicles on both road sides.…”

“…Moreover, assessing the performance of NGV STAs and their impact on non-NGV STAs, we take into account not only frame transmissions delays but also the PLR. The aforementioned drawbacks of [52] are also addressed in this paper.…”

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.
