“…On the other hand, the multi-hop relaying technology is beneficial to improve the received signal-to-noise ratio (SNR) of modulated optical data signal, thanks to the cooperative diversity gain. In view of this, the authors in [27] and [28] respectively analyzed the BER and coverage range of multi-hop V2V-VLC systems under different weather conditions, and verified that the multihop relaying can provide a significant performance gain.…”

“…Apparently, the short-packet feature is not considered in the aforementioned literatures, and thus cannot be employed for the URLLC-oriented transmission design. Hence, the theoretical analysis for URLLC in the V2V-VLC system requires a novel methodology distinct from that utilized in [21]- [28]. Apart from the short-packet feature, the extremely low transmission latency of URLLC also introduces an inevitable channel estimation error at the receiver, since the pilot length for channel training is very short [30].…”

“…On the one hand, the VLC-related literatures mentioned above [21]- [28] are based on the ideal assumption of infinite blocklength, which is no longer valid for URLLC system with short codeword blocklength. On the other hand, the URLLC-related literatures mentioned above [31]- [35] are in the category of the RF-based transmission design, which is not applicable for our V2V-VLC system.…”

Internet-of-vehicles (IoV) is an emerging paradigm with significant potential to improve traffic efficiency and driving safety. Here, we focus on the design of a novel visible light communication (VLC)-assisted scheme to enable driving safetyrelated IoV services that require ultra-reliable and low-latency communications (URLLC). Specifically, the vehicle-to-vehicle (V2V) communication mode is adopted to satisfy the ultra-low latency requirement of URLLC in roadside infrastructure-less IoV systems. In the outdoor V2V-VLC scenarios, the quality of the received optical signal is degraded by path loss, atmospheric turbulence and additive noise. In addition, the short-packet feature of URLLC introduces inevitable data decoding errors and imperfect channel state information (CSI). Against this background, we aim to investigate the reliability performance of URLLC in outdoor V2V-VLC systems, which is described by the average packet loss probability under given user-plane transmission latency. Firstly, we consider the ideal case of a perfect CSI at receiver, and derive an analytical expression of average packet loss probability. Further, a closed-form approximation is provided to simplify the numerical calculation. Next, we extend the theoretical analysis to a practical V2V-VLC system with imperfect CSI at the receiver. Through numerical results, we validate the accuracy of our designed theoretical framework and propose some preliminary ideas to enable driving safety-related IoV services in outdoor V2V-VLC systems.

“…The authors of [ 36 ] examined the deployment of relay-assisted V2V systems using a linear path loss model to extend transmission ranges. Moreover, the authors in [ 136 ] analyzed the error rate and coverage range of multi-hop V2V VLC systems under different weather conditions, employing a more realistic channel model. Their findings confirmed that multi-hop relaying can significantly enhance performance.…”
