This paper investigates the performance of NOMA-based hybrid Satellite-Terrestrial relays system (HSTR) using the millimeter wave (mmWave) technology. Furthermore, the relays are equipped with multiple antennas and utilize the amplify and forward (AF) protocol to forward the satellite's superimposed information to multiple destinations. Then, the rain coefficient is considered as the fading factor of the mmWave band to choose the best relay. We considered the shadowed-Rician fading and Nakagami-m fading for satellite links and terrestrial links respectively, and in addition, we evaluated the shadowing effect for satellite links with two modes of: frequent heavy shadowing (FHS) and average shadowing (AS). With these suggestions, the closed-form outage probability (OP) and approximate ergodic capacity (EC) are derived to evaluate the efficiency of the proposed system. Next contribution of the research is an asymptotic analysis for the OP, which is derived in order to gain additional insight into important system parameters. Finally, the theoretical derivation is validated through simulation results and analyzed the impact of significant parameters. These results demonstrate NOMA's superiority to the traditional orthogonal multiple access (OMA) method in the proposed system.INDEX TERMS NOMA, hybrid satellite-terrestrial relay system, millimeter wave, rain attenuation, outage probability, ergodic capacity.

In recent years, Internet of Things (IoT) technology has emerged and gradually sprung up. As the needs of largescale IoT applications cannot be satisfied by the fifth generation (5G) network, wireless communication network needs to be developed into the sixth generation (6G) network. However, with the increasingly prominent security problems of wireless communication networks such as 6G, covert communication has been recognized as one of the most promising solutions. Covert communication can realize the transmission of hidden information between both sides of communication to a certain extent, which makes the transmission content and transmission behavior challenging to be detected by noncooperative eavesdroppers. In addition, the integrated high altitude platform station (HAPS) terrestrial network is considered a promising development direction because of its flexibility and scalability. Based on the above facts, this article investigates the covert communication in an integrated HAPS terrestrial network, where a constant power auxiliary node is utilized to send artificial noise (AN) to realize the covert communication. Specifically, the covert constraint relationship between the transmitting and auxiliary nodes is derived. Moreover, the closed-form expressions of outage probability (OP) and effective covert communication rate are obtained. Finally, numerical results are provided to verify our analysis and reveal the impacts of critical parameters on the system performance.

“…Firstly, the CSI and SIC are crucial to the outage performance, and there have been several studies concerning this issue [23]. The CSI can be obtained with channel estimation methods, which have been adopted in most the existing works [24,25]. As the focus herein is the caching scheme, we assume that the perfect CSI is available, and the SIC is error-free.…”

To decrease the transmission delay and alleviate communication congestion, caching has been applied in the integrated satellite-terrestrial networks (ISTNs). In traditional caching schemes, the cache-enabled relays update files during off-peak hours and push them during on-peak hours. However, for the enormous number of end devices in ISTNs, the long-time waiting for off/on-peak hours would decrease the quality of service. To address this issue, this paper proposes a two-tier nonorthogonal multiple access- (NOMA-) based ISTN with wireless caching. Specifically, data transmission of this model consists of two phases. For the first phase, named the file-push-and-placement (FPAP), the satellite employs the NOMA protocol to send information to both the relay and first-tier user. While for the second phase, which is called the file-push-and-delivery (FPAD), second-tier users are served by the relay employing NOMA. Performance analysis of the proposed configuration is carried out, focusing on the exact and asymptotic outage probability (OP), diversity order, and hit probability. Moreover, the influence of key factors on the system performance is also investigated. Compared with the traditional configuration, it is shown analytically and numerically that the proposed scheme achieves lower OP and higher diversity order.
