“…In order to analyze the multilayer heterogeneous satellite network, the authors in [8] proposed a NOMA-enabled two-layer geostationary earth orbit/low earth orbit (LEO) satellite network, where the ergodic capacity of the proposed system was investigated in the case of coexistence of frequencies. In [9], a dedicated half-duplex (HD) terrestrial decode-and-forward (DF) relay was used to assist a user with weak channel condition to complete communications with the satellite. Moreover, in [10], the authors extended the work of [9] to investigate an amplify-and-forward multiantenna relay scenario and performed the performance analyses for fixed gain and variable gain relaying protocols, in which the exact and asymptotic outage probability expressions were obtained.…”

A unified nonorthogonal multiple access (NOMA) framework for satellite-terrestrial network is investigated over Shadowed-Rician fading channels, which can be applied to both power domain NOMA (PD-NOMA) and code domain NOMA (CD-NOMA). Under the realistic assumption of hardware impairments (HIs) and imperfect successive interference cancellation (SIC), the achievable outage probability of the paired users is analyzed first, and the closed-form expressions of exact and asymptotic outage probability are derived. Next, the ergodic sum rate is investigated in different levels of HIs and residual interference. In addition, the energy efficiency in the delay-tolerant transmission mode is studied to characterize the performance of the satellite-terrestrial network. Finally, the Monte Carlo simulation results demonstrate the accuracy of theoretical derivation and showcase the effects of a wide range of satellite channel parameters and the realistic assumption on outage probability, ergodic rate, and energy efficiency.

“…As mentioned before, the limited spectrum resources in the ISTRNs needs to be enhanced with high efficiency. Hence, owing to the inherent characters, the NOMA scheme has been used widely in the ISTRNs to improve the spectrum efficiency [30]- [38].In [31]- [33], the authors introduced the NOMA and cooperative NOMA schemes into the ISTRNs, especially, the performance of OP and EC were obtained to validate the superiority of the proposed framework.The authors of [34] investigated the performance of the NOMAbased integrated satellite-terrestrial networks with cooperative device-to-device (D2D) scheme, and achieved significant sum rate and spectral efficiency gains.In [35], the authors derived the closed-form expression of OP for a cooperative NOMA-based ISTRN where the user with better channel conditions was regarded as a DF relay to assist the user with worse channel conditions.The authors of [36] integrated NOMA scheme and wireless content delivery into SatCom networks, specifically, the expressions of OP and hit proba-bility were derived respectively.In [37], the authors proposed a joint optimization design of NOMA-based ISTRNs where the sum rate of the considered system was improved under satisfying transmission power limitation and quality of service (QoS) requirements.Optimization problem of NOMAbased ISTRNs was analyzed in [38] by considering the effect of perfect and imperfect channel state information (CSI) where the robust beamforming scheme was derived to evaluate the benefit of the NOMA scheme.…”

Integrated satellite terrestrial networks (ISTNs) are becoming a hot research topic in recent years due to the capabilities of high quality, high throughput, and seamless coverage. However, the limited spectrum resources are difficult to meet the needs of a large number of users in ISTNs, and the obstacles and shadowing will seriously affect the communication quality of networks. In this regard, cooperative transmission of non-orthogonal multiple access (NOMA)-assisted ISTNs with the help of multiple terrestrial relays are established to enhance the spectrum efficiency and enlarge the transmission coverage. In this paper, we investigate the performance of NOMA-based ISTNs with relay selection and imperfect successive interference cancellation (SIC). Particularly, the partial relay selection (PRS) scheme is used in the considered system to reach the balance of system performance and complexity. Owing to practical constraints, the imperfect SIC is analyzed for the networks. Based on the PRS scheme and imperfect SIC, we obtain the closed-form expressions for the outage probability (OP) and ergodic capacity (EC) of the considered networks. Besides, to get further insights of key system parameters, the asymptotic analysis for the OP is also derived. Finally, numerical and simulation results are presented to validate the correctness of our analytical results. INDEX TERMS Integrated satellite terrestrial networks (ISTNs), non-orthogonal multiple access (NO-MA), relay selection, successive interference cancellation (SIC).

“…In particular, the authors also demonstrated that with DF relaying, R-NOMA provides better user fairness than cooperative NOMA (C-NOMA). The outage probability of a multi-antenna relay-based hybrid satellite-terrestrial network was investigated in [14]. In [15], the ergodic sumrate performance of the R-NOMA system was analyzed for both AF and DF relaying schemes considering Nakagami-m fading channels.…”

This paper investigates the performance of a new framework for low-outage downlink non-orthogonal multiple access (NOMA) using a coordinated direct and relay transmission (CDRT) scheme with direct links to both the nearuser (NU) and the far-user (FU). Both AF and DF relays are considered. In this framework, the NU combines the signals from BS and R at each stage of the successive interference cancellation (SIC) to attain good outage performance. For both NU and FU, the expressions for outage probability and throughput are derived in closed form. We also derive the high-SNR expressions for the outage probability to demonstrate that with the proposed framework, both users harness a diversity of two without feedback bits (this is the only framework to achieve this). We demonstrate that the choice of power allocation coefficient and target symbol rates is crucial to maximizing the NU throughput while ensuring a desired target FU throughput. We demonstrate that CDRT with the proposed framework outperforms known schemes in terms of outage probability, sum throughput, and energy efficiency. Moreover, we also show that optimal rate selection is important to maximize the EE. Monte Carlo simulations validate the accuracy of the derived analytical expressions.Index Terms-Non-orthogonal multiple access (NOMA), coordinated direct and relay transmission (CDRT), energy efficiency (EE), amplify-and-forward (AF), decode-and-forward (DF).
