“…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]. The authors in [42] proposed a dynamic retransmission strategy for the two-user uplink NOMA scenario with HARQ and multiple allowed retransmissions.…”

<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>

“…The two-user donwlink NOMA with HARQ under the finite block length assumption was also considered in the literature [10], [11], [45], [46], where the throughput and packet error rate were analyzed and power level optimization was carried out. While these papers shed light on the overall performance of NOMA with retransmissions in the finite block length regime, NOMA with HARQ for short packet communications in the uplink of cellular systems has not been thoroughly investigated.…”

In this paper, we consider the massive nonorthogonal multiple access (NOMA) with hybrid automatic repeat request (HARQ) for short packet communications. To reduce the latency, each user can perform one re-transmission provided that the previous packet was not decoded successfully. The system performance is evaluated for both coordinated and uncoordinated transmissions. We first develop a Markov model (MM) to analyze the system dynamics and characterize the packet error rate (PER) and throughput of each user in the coordinated scenario. The power levels are then optimized for two scenarios, including the power constrained and reliability constrained scenarios. A simple yet efficient dynamic cell planning is also designed for the uncoordinated scenario. Numerical results show that both coordinated and uncoordinated NOMA-HARQ with a limited number of retransmissions can achieve the desired level of reliability with the guaranteed latency using a proper power control strategy. Results also show that NOMA-HARQ achieves a higher throughput compared to the orthogonal multiple access scheme with HARQ under the same average received power constraint at the base station.
