“…Firstly, as the bandwidth of FSO systems is much larger than that of RF ones, it is challenging for error-control methods designed for the lower data-rate transmission of RF systems to fully exploit such huge bandwidth. As a matter of fact, for example, the stop-and-wait (SW) ARQ protocol has been widely employed and performed well in RF communications [56]- [58]. This protocol, nevertheless, may not be suitable for high-speed FSO systems due to its inefficient bandwidth utilization, as reported in [34].…”

Free-space optical (FSO) communications have gained significant interest over the last few years, thanks to the capability to transport extremely high-speed data over long distances without exhausting radio frequency (RF) resources. FSO communication is widely considered in various network scenarios, such as inter-satellite/deep-space links, ground-station/vehicles, satellite/aerial links, or terrestrial links. It is expected to be a key enabling technology for the next generation of 6G wireless networks. Nevertheless, despite the great potential of FSO communications, its performance suffers from various limitations and challenges: atmospheric turbulence, clouds, weather conditions, and pointing misalignment. The error-control solutions, including physical layer (PHY) and link-layer methods, aim to mitigate the transmission errors caused by such adverse issues. While the existing surveys on error-control solutions in FSO systems primarily focussed on the PHY methods, we instead provide a review of link-layer solutions. In particular, we conduct an extensive literature survey of state-of-the-art retransmission protocols, both automatic repeat request (ARQ) and hybrid ARQ (HARQ), for various FSO communication scenarios, including point-to-point terrestrial, cooperative, multi-hop relaying, hybrid FSO/RF, satellite/aerial, and deep-space systems. Furthermore, we provide a survey of recent literature and insightful discussion on the cross-layer design frameworks related to link-layer retransmission protocols in FSO communication networks. Finally, the lessons learned, design guidelines, related open issues, and future research directions are exposed.

For example, the stop-and-wait (SW) ARQ protocol performs well in RF communications [45]- [47].

“…Such a BS configures the DL-NOMA parameters, such as the assigned power levels based on the channel gains between the BS and receivers. Reference [14] proposed a NOMA scheme using the automatic repeat request (ARQ) for exchanging short packets, in which the transmitter adaptively superposes only packet signals indicating a negative acknowledgment (NACK). The proposed method is a broadcast network, and thus, using ARQ is difficult.…”

This paper proposes a probabilistic cooperative transmission scheme with non-orthogonal multiple access (NOMA), named NO-ProbReM, for the PC5-based cellular-vehicle-to-everything (C-V2X) mode 4 in the crash warning system (CWS). In the proposed method, each node probabilistically selects a packet based on its cooperation ability under a limited cooperation power level, which is assigned within the total transmission power limit; then, the node superposes its own packet signal and the selected packet signal on a NOMA basis. The proposed probabilistic mechanism autonomously improves the link reliability within a specific range by the limited-assigned cooperation power while guaranteeing that the direct link is sufficiently similar reliability to mode 4. Our simulation results demonstrated that with suitable parameters, the proposed method mitigated the potential channel congestion of the current mode 4; in particular, the proposed method provided 50% better performance than the current mode 4 in the fundamental node density model. These results highlight that the proposed method advanced the infrastructure-less C-V2X in the CWS.
