“…Due to the wide coverage of the satellite beam, one satellite beam often covers many terrestrial users, thus multiple relays scenario in the ISTRNs is a common scene [21], [22]. To obtain the balance between the system performance and system complexity, relay selection scheme is often considered in the multiple terrestrial relay networks [23]- [29]. In [23]- [25], two-stage relay selection schemes were considered in cooperative NOMA-based terrestrial wireless communication systems, where relays were working in full-duplex (FD) or half-duplex (HD) mode with amplify-and-forward (AF) or DF protocol, and the system can get superior outage behaviors.…”

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).

“…Over the last few years, the CR-inspired non-orthogonal multiple access (NOMA) scheme has received considerable attention scenarios [29]- [31], as the NOMA scheme encourages spectrum sharing among transmission nodes, which not only improves the spectral efficiency but also ensures massive connectivity that can be effectively supported. [22], [23], [32] integrated the NOMA scheme into the cognitive hybrid satellite-terrestrial overlay network, where the NOMA scheme further improves the achievable performance. However, these works are restricted to a simplified single user and single-channel scenario.…”

“…However, the Vickrey auction mechanism is only suitable for a single commodity. In [32], the authors proposed a relay selection based on the Vickrey auction mechanism to allow secondary networks to compete for one cooperative spectrum sharing channel, but they did not consider multi-channel systems. The Vickrey-Clarke-Groves (VCG) mechanism, a natural extension of the Vickrey multiunit auction, provides a ready means of achieving resource allocation efficiency [35].…”

In this paper, we investigate the multi-channel cooperative spectrum sharing in hybrid satellite-terrestrial internet of things (IoT) networks with the auction mechanism, which is designed to reduce the operational expenditure of the satellitebased IoT (S-IoT) network while alleviating the spectrum scarcity issues of terrestrial-based IoT (T-IoT) network. The cluster heads of selected T-IoT networks assist the primary satellite users transmission through cooperative relaying techniques in exchange for spectrum access. We propose an auction-based optimization problem to maximize the sum transmission rate of all primary S-IoT receivers with the appropriate secondary network selection and corresponding radio resource allocation profile by the distributed implementation while meeting the minimum transmission rate of secondary receivers of each T-IoT network. Specifically, the one-shot Vickrey-Clarke-Groves (VCG) auction is introduced to obtain the maximum social welfare, where the winner determination problem is transformed into an assignment problem and solved by the Hungarian algorithm. To further reduce the primary satellite network decision complexity, the sequential Vickrey auction is implemented by sequential fashion until all channels are auctioned. Due to incentive compatibility with those two auction mechanisms, the secondary T-IoT cluster yields the true bids of each channel, where both the non-orthogonal multiple access (NOMA) and time division multiple access (TDMA) schemes are implemented in cooperative communication. Finally, simulation results validate the effectiveness and fairness of the proposed auction-based approach as well as the superiority of the NOMA scheme in secondary relays selection. Moreover, the influence of key factors on the performance of the proposed scheme is analyzed in detail.

“…The secrecy outage probability of the hybrid satellite-terrestrial network was analyzed to indicate the secrecy performance by introducing the closed-form formula for the single-relay selection and baseline roundrobin scheduling modes [12]. By using Vickrey auction to achieve an efficient secondary relay selection, a cooperative spectrum sharing scheme is examined in the scenario of a multi-potential secondary relay selection [13]. X. Zhang et al studied the generalized shadowed-Rician fading for satellite links while Nakagami-m fading is adopted in terrestrial links.…”

In this paper, a hybrid satellite-terrestrial spectrum sharing system allows terrestrial secondary network to cooperate with a primary satellite network and to further provide higher spectrum efficiency. For massive connections design, we implement non-orthogonal multiple access (NOMA) technique to form cognitive radio based satellite-terrestrial (CR-NSHT) system relying on NOMA and further achieve more benefits compared with traditional schemes. The secondary network only remains its stable operation when the outage probability of such system is guaranteed, and thereby, to explore advantages of spectrum sharing opportunities. Considering Shadowed-Rician fading for satellite links, and Nakagami-m as well as Rician fading for terrestrial links, we derive the closed-form expressions of the outage probability to evaluate performance of secondary network. We find that several impacts on performance metrics such as power allocation factors, transmit signal to noise ratio (SNR) at the source, parameters of satellite links, target rates and values of fading channels. We consider further system performance metrics including ergodic capcity, energy efficiency and multi-user scenarios. Numerical and simulation results validate our analysis and highlight the performance gains of the proposed schemes for CR-NSHT with relay link serving secondary network and direct link serving the primary network.INDEX TERMS Hybrid satellite-terrestrial systems, cognitive radio, spectrum sharing, outage probability.
