“…A TRIS is used in the secondary network to manage the secondary network's interference and prevent information leakage. More recently, a more complicated ARIS-assisted CR network was studied in [116]. In particular, the primary transmitter communicates with multiple primary GUs but is interfered by the secondary network, where the secondary transmitter transmits the information to multiple secondary GUs with the help of ARIS.…”

| Nonterrestrial communications have emerged as a key enabler for seamless connectivity in the upcoming generation networks. This kind of network can support high data rate communications among aerial platforms (i.e., unmanned aerial vehicles (UAVs), high-altitude platforms (HAPs), and satellites) and cellular networks, achieving anywhere and anytime connections. However, there are many practical implementation limitations, especially overload power consumption, high probability of blockage, and dynamic propagation environment. Fortunately, the recent technology reconfigurable intelligent surface (RIS) is expected to be one of the most cost-efficient solutions to address such issues. RIS with low-cost elements can bypass blockages and create multiple line-of-sight (LoS) links and provide controllable communication channels. In this article, we present a comprehensive literature review on the RIS-assisted nonterrestrial networks (RANTNs). First, the framework of the RANTNs is introduced with detailed discussion about distinct properties of RIS in NTNs and the two Manuscript

“…In [26], the authors considered multiple UAVs communication networks carrying RISs and clustered the ground users to finally maximized the minimum rate for multi-user clusters. The authors of literatures [27,28] considered all the security issues to improve the security performance of the communication network with the help of UAVs and RIS. The authors in [29][30][31] all considered the multi-user models.…”

“…We have also done the detailed research on related work. The combination of UAVs and RIS can usually be divided into two types, which are UAVs carrying RIS [25][26][27][28] and RIS built on the surface of buildings [29][30][31][32][33][34][35]. The authors in [25] maximized the user's information rate by alternately optimizing the position of the UAV and the phase of the RIS.…”

“…The communication network in the literature [12][13][14] only considered UAVs, while the communication system in [21,22] only considered RIS. Although the secure networks were considered in [27,28] as well as in [32][33][34][35] for UAVs and RIS, they are single UAV models. Thus, in this paper, we construct a UAVs secure communication network.…”

Unmanned aerial vehicles (UAVs) are widely used in wireless communication networks due to their rapid deployment and high mobility. However, in practical scenarios, the existence of obstacles and eavesdroppers will seriously interfere with the communication quality of the UAV network and produce a security risk. Thus, this paper combines reconfigurable intelligent surface (RIS) technology with UAVs to build a secure UAV communication network. Normally, a rotary-wing UAV (labeled as UAV-S) acting as a base station sends information signals to a legitimate user on the ground with RIS equipment. However, there is a passive eavesdropper on the ground who can steal the information. Therefore, a friendly UAV jammer (labeled as UAV-J) with a fixed location is introduced to send jamming signals to confuse the eavesdropper. The goal of this paper is to maximize the average secrecy rate of the communication network by jointly optimizing the flight trajectory, transmit power of the UAV-S and UAV-J, and phase shifter of the RIS. Since the constructed problem is highly nonconvex, an alternating optimization algorithm based on successive convex approximation techniques is proposed to solve the problem. Simulation results show that the proposed algorithm can achieve a higher secrecy rate in comparison with other schemes.
