“…Adaptive power allocation for HARQ-CC and HARQ-IR are studied in [123], [263], [264] to ensure low errors or delays in NOMA systems. Moreover, dynamic UE pairing in NOMA based systems is proposed in [265] where different UE pairs may be considered in each retransmission with the objective to improve the transmission diversity, delay, and fairness.…”

Automatic repeat request (ARQ) schemes, and in particular hybrid-ARQ (HARQ) schemes, which jointly adopt forward error correction (FEC) and ARQ, are essential to provide reliable data transmission in wireless communications systems. However, the feedback from the receiver to the transmitter and the retransmission process used in ARQ incurs significant cost in terms of power efficiency, throughput, computational power and delay. Unfortunately, such drawbacks can limit their applications to several current and emerging technologies. More specifically, the increasing number of wireless users has create spectrum scarcity, relying on small-size batteries create power constraints, deployment of real-time applications boost the demand for ultralow delay networks, and the ultra-small low-cost internet of things (IoT) devices has limited signal processing and computation capabilities. Consequently, extensive research efforts have been dedicated to overcome the limitations inherent in HARQ. This survey paper provides an extensive literature review of the stateof-the-art HARQ techniques and discusses their integration in various wireless technologies. Moreover, it provides insights on advantages and disadvantages of particular ARQ types and discusses open problems and future directions.

“…The performance of the HARQ-CC and HARQ with incremental redundancy (IR) aided NOMA systems is studied in [39] where the performance is evaluated in terms of outage probability. A dynamic power allocation scheme is presented in a NOMA-HARQ based transmission scheme in [40], leading to a reduced number of retransmissions. The performance of two users on the downlink NOMA using HARQ-CC is studied in [41].…”

<p> Data download and storage over wireless networks is a popular application for various multimedia such as images, audio, and video files. In such applications, the end-user may listen to or watch the downloaded media in real-time, and/or will playback the downloaded file multiple times in the future. Consequently, improving the quality of the stored multimedia will be highly desirable by the end-user, even if the initial real-time version had less quality. Therefore, this work proposes a novel technique to improve the throughput of wireless networks that adopt nonorthogonal transmission and automatic repeat request (ARQ). Unlike conventional systems, the proposed scheme stores the dropped data packets for further offline processing where some packets can be recovered by applying successive interfer-ence cancellation (SIC) in a retroactive manner. Consequently, the proposed packet repair and recovery (PRR) scheme can improve the reliability of the received data without additional packet retransmission, which may offer a significant throughput gain. To evaluate the effectiveness of the proposed scheme, it is applied to image transmission for transportation systems. The obtained results confirm that a considerable portion of the dropped packets can be successfully recovered and the visual quality of the received image can be improved. In particular scenarios, the obtained results show that the proposed PRR technique managed to reduce the packet drop rate (PDR) from 10^{−1} to 10^{−3}, i.e., 100 fold, which implies that 99% of the packets that were initially dropped were successfully recovered.</p>
