“…To evaluate the feasibility of MIMO-NOMA systems in THz bands, Sabuj et al proposed in [425] a finite blocklength (FBL) channel model and therewith evaluated the system performance regarding critical machine-type communications (CMTC) scenarios. In contrast to its good performance in LoS scenarios, THz-NOMA performs much more poorly when the connected devices are blocked by obstacles [426].…”

“…4 shows a drop in carrier frequency with fast fluctuations. This is because a THz connection consists of both spreading and molecule absorption losses [54][55][56]. The attenuation caused by the propagation properties of a wave across the medium is known as the spreading loss (or freespace loss).…”

This paper discusses the significance and prospects of low altitude small satellite aerial vehicles to ensure smooth aerial-ground communications for next-generation broadband networks. To achieve the generic goals of fifthgeneration and beyond wireless networks, the existing aerial network architecture needs to be revisited. The detailed architecture of low altitude aerial networks and the challenges in resource management have been illustrated in this paper. Moreover, we have studied the coordination between promising communication technologies and low altitude aerial networks to provide robust network coverage. We talk about the techniques that can ensure userfriendly control and monitoring of the low altitude aerial networks to bring forth wireless broadband connectivity to a new dimension. In the end, we highlight the future research directions of aerial-ground communications in terms of access technologies, machine learning, compressed sensing, and quantum communications.

“…At present, only TDD installations are being evaluated at these frequencies. Although most immediate RIS applications are intended for FR1 and FR2 frequencies, as specified by the third-generation partnership project (3GPP), THz and sub-THz communications are gaining popularity for future 6G networks due to their high bandwidth and channel capacity support [110]. As communication at these RF ranges is inherently short-ranged and unstable, with intermittent communications hampered by obstruction and absorption, a constant LOS link needs to be ensured.…”

<p>The development of our neoteric scientific fields has reached such a magnificent level that the benefits from innovation have extended to all regions, including those most distant. Modern information and communication network systems have greatly improved the overall effectiveness and performance of the wireless networks. With the emergence of cellular networks, the wireless communication network system has evolved from the first generation to the sixth generation (6G), which will provide an integrated framework for a variety of utilities and applications. The goal of 6G network systems is to improve channel capacity, low bit rate error, efficient signal transmission, and low latency while providing reliable connectivity and seamless communication. Various technologies are integrated with 6G network systems to provide controlled, efficient, and reliable communication. One emerging technology for 6G communication network systems is reconfigurable intelligent surfaces (RIS), which is ideal for smooth and controllable wireless signal transmission. RIS uses smart beamforming methods with the assistance of an electronic circuit controller to provide superior signal quality. This study presents a complete overview of RIS, including its hardware architecture, key characteristics, control mechanism, operating frequency, communication duplex mode, and operating mode. The study also elaborates on the RIS operational environment, advantages of implementing RIS, deployment, and different types of communication by utilizing RIS. Finally, we conclude with a discussion of challenges and future research directions to overcome limitations to achieve the goal of RIS implementation and RIS-aided communication for 6G communication systems.</p>
