“…For example, the work in [36] proposed a network with a single relay, and due to its position, the near user may act as another relay that forwards satellite-sent data to the weak user. The work in [37] generally considers the same configuration [36] in but with multiple relays. The work in [38] considers that the relay performs amplify-and-forward (AF) using multiple antennas.…”

This article presents a novel framework for integrating low-earth orbit satellites (LEOSs) with terrestrial-wired networks to improve coverage, throughput, and transmission reliability of 6th generation (6G) Internet of things (IoT) networks. The proposed framework utilizes the synergy of non-orthogonal multiple access (NOMA), automatic repeat request (ARQ), and cooperative communications to maximize the data downloaded from a LEOS to multiple terrestrial users. More specifically, we propose a novel offline packets repair and recovery (PRR) technique to reduce the number of dropped packets, where the wired-terrestrial connection is used to enable efficient bidirectional cooperation, to improve the reliability of the received data by reducing the multiuser interference inherent to NOMA. Moreover, by exchanging the acknowledgment messages used with ARQ, efficient Chase combining (CC) is applied to improve the signal to noise ratio (SNR) of the received packets. Extensive Monte Carlo simulation experiments are used to evaluate and quantify the advantages of the proposed system. The results obtained show that the proposed system can repair a significant number of dropped packets, which reduces the packet drop rate and improves the network throughput. In several scenarios, the proposed PRR managed to repair and recover more than 90% of the dropped packets.Index Terms-6th generation (6G), automatic repeat request (ARQ), non-orthogonal multiple access (NOMA), throughput, maximum ratio combining (MRC), Chase combining (CC), packet drop rate.

“…At same network, CCI can purposely be used as a part of source of energy harvesting (EH) to empower the relay nodes. In the existing work, decode-and-forward (DF) relaying mechanism [12]- [13] is studied to analyse the network performance of RF-EH enabled one-way SU communication considering both good and bad impacts of interference [14]- [16]. SU outage performance along with ergodic capacity is analysed in [14] for underlay mode of CCRN considering both delay-tolerant and delaylimited transmission.…”

This paper studies the effect of co-channel interference (CCI) on energy harvesting (EH) from radio frequency (RF) signal and the performance of reliable communication. An overlay mode of cooperative cognitive radio network (CCRN) model is considered that may support one-way communication between primary users (PUs) and two-way communications between secondary users (SUs). Closed form PU and SU outage expressions are derived in presence of CCI at two SU nodes and multiple antennas at PU transmitter. The absolute impact of CCI on the performance of the proposed system is analysed with respect to various parameters like, transmission power, interference-to-noise-ratio (INR), power splitting factor, number of CCI sources and number of antennas. About 20% and 15% improvements are achieved for PU and SU outage using two antennas compared to single antenna system model.

“…The works [17,18] were to maximize the sum rate of satellite-terrestrial relay networks by using joint reinforcement learning as well as Karush-Kuhn-Tucker algorithm and Q-learning algorithm, respectively. Taking the transmit reliability as the target, the authors in [19] proposed a relaying protocol and a three-stage relay selection strategy to minimize the system outage probability.…”

In this paper, we theoretically study the achievable capacity of orthogonal and non-orthogonal multiple access (OMA and NOMA) schemes in supporting downlink satellite communication networks. Considering that various satellite applications have different delay quality-of-service (QoS) requirements, the concept of effective capacity is introduced as a delay-guaranteed capacity metric to represent users’ various delay requirements. Specifically, the analytical expressions of effective capacities for each user achieved with the NOMA and OMA schemes are first studied. Then, approximated effective capacities achieved in some special cases, exact closed-form expressions of users’ achievable effective capacity, and the capacity difference between NOMA and OMA schemes are derived. Simulation results are finally provided to validate the theoretical analysis and show the suitable limitations of the NOMA and OMA schemes, such as the NOMA scheme is more suitable for users with better channel quality when transmit signal-to-noise (SNR) is relatively large, while it is suitable for users with worse link gain when transmit SNR is relatively small. Moreover, the influences of delay requirements and key parameters on user selection strategy and system performance are also shown in the simulations.
