“…In order to transmit high-resolution LFV-based holograms, holographic communication requires a data rate of several Tbps, while current 5G networks cannot support it [266], [267]. Featuring higher frequency and larger bandwidth compared with mmWave in 5G, THz communications have the potential to support holographic communication with Tbps-level data rate [268], [269]. To overcome the severe propagation loss of THz communication, dense deployment of access points and extremely narrow beams can be adopted to improve connection density and communication reliability [270].…”

The sixth generation (6G) networks are expected to enable immersive communications and bridge the physical and the virtual worlds. Integrating extended reality, holography, and haptics, immersive communications will revolutionize how people work, entertain, and communicate by enabling lifelike interactions. However, the unprecedented demand for data transmission rate and the stringent requirements on latency and reliability create challenges for 6G networks to support immersive communications. In this survey article, we present the prospect of immersive communications and investigate emerging solutions to the corresponding challenges for 6G. First, we introduce use cases of immersive communications, in the fields of entertainment, education, and healthcare. Second, we present the concepts of immersive communications, including extended reality, haptic communication, and holographic communication, their basic implementation procedures, and their requirements on networks in terms of transmission rate, latency, and reliability. Third, we summarize the potential solutions to addressing the challenges from the aspects of communication, computing, and networking. Finally, we discuss future research directions and conclude this study.

“…A promising candidate frequency band for wideband communication is terahertz (THz), which can deliver ultra-high transmission rates, i.e., several Tbps [6], [7]. However, despite the many advantages of the THz band, establishing a reliable transmission link at THz frequencies remains a challenge in industrial wireless communications.…”

The Industrial Internet of Things (IIoT) enables industries to build large interconnected systems utilizing various technologies that require high data rates. Terahertz (THz) communication is envisioned as a candidate technology for achieving data rates of several terabits-per-second (Tbps). Despite this, establishing a reliable communication link at THz frequencies remains a challenge due to high pathloss and molecular absorption. To overcome these limitations, this paper proposes using intelligent reconfigurable surfaces (IRSs) with THz communications to enable future smart factories for the IIoT. In this paper, we formulate the power allocation and joint IIoT device and IRS association (JIIA) problem, which is a mixed-integer nonlinear programming (MINLP) problem. Furthermore, the JIIA problem aims to maximize the sum rate with imperfect channel state information (CSI). To address this non-deterministic polynomial-time hard (NP-hard) problem, we decompose the problem into multiple sub-problems, which we solve iteratively. Specifically, we propose a Gale-Shapley algorithm-based JIIA solution to obtain stable matching between uplink and downlink IRSs. We validate the proposed solution by comparing the Gale-Shapley-based JIIA algorithm with exhaustive search (ES), greedy search (GS), and random association (RA) with imperfect CSI. The complexity analysis shows that our algorithm is more efficient than the ES.

“…To meet rising bandwidth needs, wireless communication's frequency spectrum has been steadily growing. Terahertz (THz)-band communications [4][5] will be crucial for the next 6G [6][7][8] and beyond, even if millimeter-wave band communications [2][3] are already influencing the 5G. The final uncharted region of the radio-frequency spectrum is the THz band, which is located between optical bands and microwave.…”

<p> Unmanned aerial vehicles (UAVs) are safer than manned vehicle and raise the interest to researchers for their huge applications in 5G and upcoming 6G. In 6G, terahertz (THz)-band communications can be used for fast communication. In this paper, the THz wireless communication between UAVs is considered. The performance of UAVs communications in the THz networks is analyzed under different fading channels which are major influence factors in the THz communication channel modeling. It is crucial to assess the performance of wireless devices taking into account their structure, wireless channel parameters, and transmission characteristics. Log-normal Fading, Weibull Fading Channel, Nakagami-m Fading Channel, Rician Fading Channel and Rayleigh Fading Channel are taken into account. Performance influencing parameters are considered and analytical expressions concerning capacity, outage probability, and bit error rate (BER) are obtained. Numerical results are presented which verify the analytical analysis. </p>
