IEEE Photonics Journal, 2014 In this paper, we investigate the performance of hybrid automatic repeat request (HARQ) with incremental redundancy (IR) and with code combining (CC) from an information-theoretic perspective over a point-to-point free-space optical (FSO) system.

Backlog and Delay Reasoning in HARQ System
2015 27th International Teletraffic Congress, 2015 Recently, hybrid-automatic-repeat-request (HARQ) systems have been favored in particular state-of-the-art communications systems since they provide the practicality of error detections and corrections aligned with repeat-requests when needed at receivers.

Rate Adaptation for Secure HARQ Protocols [PDF]
IEEE Transactions on Information Forensics and Security, 2018 This paper investigates the incremental-redundancy hybrid-automatic repeat request (IR-HARQ) transmission over independent block-fading channels in the presence of an eavesdropper, where the secrecy of the transmission is ensured via introduction of dummy-messages.

Practical cross-layer testing of HARQ-induced delay variation on IP/RTP QoS and VoLTE QoE
EURASIP Journal on Wireless Communications and Networking, 2021 As the PHY/MAC-layer IR-HARQ and RLC-layer ARQ error recovery procedures, adopted in LTE, may impose additional delay when their code-block retransmissions occur, the arising question is whether these significantly contribute to IP and consequently RTP ...

Performance of Cognitive Selective-Repeat Hybrid Automatic Repeat Request
IEEE Access, 2016 In this paper, a novel transmission protocol is proposed based on the classical selective-repeat hybrid automatic repeat to access a primary user (PU) channel, which is referred to as the CSR-HARQ.

Enhancing Reliability in 5G NR V2V Communications Through Priority-Based Groupcasting and IR-HARQ
IEEE Access, 2023 Vehicle-to-vehicle (V2V) communication is a technology that can wirelessly exchange information on the speed and position of nearby vehicles, helping to avoid collisions, to alleviate traffic congestion, and to improve the environment. The 3rd Generation

Pregabalin Efficacy in Treatment of Chronic Neurogenic Cough
The Laryngoscope, EarlyView.The use of neuromodulators for chronic cough has increased; however, the choice of medication, dosing regimen, and duration are still unclear. This longitudinal study of 95 adults taking pregabalin, 75 mg twice daily, for CNC demonstrated 78% improvement or resolution of cough, 17% unchanged, 1% worse cough, with a mean of 6 weeks of therapy, and only ...
