“…Besides, pure ARQ usually fails to provide satisfactory delay and throughput performance for high-latency systems, as they require many retransmissions for erroneous frames [62]. Several studies on the design of HARQ protocols have been reported for HAP-to-HAP [106], [127] and LEO satellite [109], [113], [115], [129] systems.…”

“…Type II-HARQ aided LEO satellites: Unlike inter-HAP systems, where the simple TI-HARQ can be used, a more robust HARQ variant should be considered for FSO-based LEO-to-ground links experiencing various adverse issues, such as atmospheric turbulence, cloud coverage, atmospheric at-tenuation, and pointing misalignment. The design of type II-HARQ, including CC and IR schemes, was considered for such links [109], [113], [115], [129], in which a summary of these works is as follows.…”

“…By using the multi-frame interleaving scheme, the proposed CC-HARQ can offer a significant throughput performance compared to the conventional one in strong turbulence conditions. • IR-HARQ Design: A novel design of IR-HARQ based sliding window mechanism was introduced in [113], [129]. Moreover, its integration with PHY adaptive multirate scheme was considered to further enhance the system performance [113].…”

“…• The state-of-art on HARQ protocols revealed that IR-HARQ is the most efficient variant for different FSO system scenarios, thanks to retransmissions of only redundancy codewords for jointly decoding with the previously received ones. • Aside from [112], [113], [129], most of the studies addressed the use of SW mechanism for the operation of HARQ protocols for the sake of simplicity in the analysis. • A lot of studies on the HARQ protocol focussed on analyzing its performance over turbulence fading channels from an information-theoretic approach, e.g., [101], [102], [104], [107], [110], [111].…”

Free space optical (FSO) communication has established a reputation for itself capable of delivering high-speed data services over long distances without exhausting radio frequency (RF) resources. FSO communication can be considered in different network scenarios, including inter-satellite/deep-space links, ground-station/vehicles, satellite/aerial links, and terrestrial links. It is expected to be one of the key enabling technologies 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 linklayer methods, aim to mitigate the transmission errors caused by such adverse issues. While the existing surveys on errorcontrol 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-ofthe-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 deepspace 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.
