This paper considers a reconfigurable intelligent surface (RIS) assisted single-input multiple-output (SIMO) sym-biotic radio (SR) system in which an RIS serves as a secondary transmitter (STx) to communicate with a cooperative receiver (C-Rx). The received signals from both primary transmitter (PTx) and the RIS are jointly decoded at the C-Rx using maximum likelihood (ML) detection. In this paper, we are interested in the RIS design to minimize the bit error rate (BER) of the SR system. Considering the coupling effect between the primary and secondary transmissions, we formulate the primary BER minimization problem with the passive energy constraint of each reflecting element at RIS, which can also enhance the secondary BER performance. To solve the formulated problem, a two-step algorithm is proposed based on the semidefinite programming (SDP) and one-dimensional search approaches. Simulation results show that the proposed algorithm outperforms the random beamforming scheme and that the BER performance of both the primary and secondary transmissions are improved when the number of reflective elements in the RIS is sufficiently large. Moreover, even under the random scheme, the BER performance of the secondary transmission is enhanced with growing number of elements at RIS.

This paper presents orbital angular momentum (OAM) multiplexing transmission with Butler matrices implemented on a sub-terahertz (sub- THz) band for the first ever to our best knowledge. Sub- THz bands enable us to utilize a wide frequency bandwidth for high-capacity wireless transmission. However, the baud rate becomes extremely high as the bandwidth widens, so digital spatial equalization becomes a significant hurdle for implementation. We therefore consider it practical to move part of the function over to analog devices. A Butler matrix is an analog device that can perform discrete Fourier transform (DFT) calculations, and a combination of the Butler matrix and uniform circular array (UCA) can be used to perform the generation and separation of OAM waves. In this paper, we present 4×4 Butler matrices for the generation and separation of four OAM waves (OAM modes 0, ±1, 2) and demonstrate a physical layer data rate of more than 100 Gbit/s for OAM multiplexing transmission over a 10-GHz bandwidth on a sub-THz band.

Wireless interference identification plays a key role in improving the performance of mobile communication systems in terms of empowering smarter scheduling. This paper proposes to apply the convolutional neural network (CNN) to identification of wireless interference, by constructing a novel multi-level identifier which works on three different time granularities and combines the results. Exploiting the powerful feature extraction ability of CNN, the proposed approach can identify and locate 7 types of interference with high accuracy, and an adaptive threshold is calculated based on the identification result for smart scheduling. Simulation results verify that the proposed multi-level method can improve the accuracy of interference identification significantly, and achieve smart scheduling as well as increase the throughput of the network.

The softwarized infrastructure of Software-Defined Industrial Internet of Things (SDIIoT) offers a cost-effective solution to improve flexibility and reliability in network management but faces several critical challenges. First, th Majority of SDIIoT entities operate over wireless channel, which expose them to a variety of attacks (e.g., man-in-the-middle, replay, and impersonation attacks) and also the centralized nature of SDN controller is prone to single point attacks. Second, network traffic in the SDIIoT is associated with large scale, high dimension and redundant data, all of which present significant hurdles in the development of efficient flow analyzer. In this regard, we present a novel blockchain and Deep Learning (DL) integrated framework for protecting confidential information and hunting cyber threats against SDIIoT and their network traffic. First the blockchain module is proposed to securely transmit industrial data from IIoT sensors to controllers of SDN via forwarding nodes (i.e., OpenFLow switches) using Clique Proof-of-Authority (C-PoA) consensus mechanism. A novel flow analyzer based on DL architecture named LSTMSCAE-AGRU is designed by combining Long Short-Term Memory Stacked Contractive AutoEncoder (LSTMSCAE) with Attention-based Gated Recurrent Unit (AGRU) at the control plane. The latter first extracts low-dimensional features in an unsupervised manner, which is then fed to AGRU for hunting anomalous switch requests. The proposed framework can withstand a variety of well-known cyber threats and mitigate the single point of controller failure problem in SDIIoT.

As the need for limitless connectivity surges, non-terrestrial networks (NTN) will play a central role in fifth generation (5G) and beyond communications. The 3rd Gener-ation Partnership Project (3GPP) defines NTN as networks, or segments of networks, using an airborne or space-borne vehicle as a relay node or base station. An NTN-enhanced cellular network supplements a conventional terrestrial cellular network. This article provides an overview of NTN-enhanced cellular networks with a particular focus on satellite-mobile direct communications. First, we review satellite system classifications such as Geostation-ary Orbit (GEO), Medium Earth Orbit (MEO), and Low Earth Orbit (LEO), spectrum usage, and key challenges of satellite communications. We then summarize recent 3GPP activities in NTN. In addition, we describe our recent proof-of-concept system involving a satellite channel emulator and modification of the 5G New Radio (NR) protocol stack to handle the challenge of long round-trip time - demonstrating the feasibility of NTN and the adoption of NTN-enhanced cellular networks in 5G and beyond communications. Finally, we highlight the main open issues and future research challenges of NTN-enhanced cellular networks.

This paper develops a distributed algorithm for user association of a rate-splitting multiple access (RSMA) network in the millimeter wave (mmWave) directional beamforming environment. In the RSMA network, hybrid multiple access (HMA) is employed based on beamforming techniques with mmWave transmission so that non-orthogonal and orthogonal multiple access users are allowed to coexist, but all users are not necessarily accessible to each other. Thus, a basic NOMA pairing principle of grouping the largest rate-gap users may not be the best strategy for the user-resource allocation, and the identification of the optimal pairing gives rise to a significant computation complexity. To handle this, a novel distributed solution is developed based on the message-passing framework among locally accessible users for the objective of maximizing the global network sum-throughput utility. To provide the optimality and the convergence of the developed algorithm, a theoretical analysis is conducted along with numerical results evidencing the superiority over existing schemes.

Millimeter-wave (mmWave) communication together with beamforming technology is envisioned as key technologies to offer greater bandwidths than previously available. In this paper, we propose a novel semi-deterministic multiple-input multiple-output (MIMO)-based beam channel model for mm Wave communications. First, the transceiver's MIMO-based beams filter out scatterers located outside the beam intersection and the cluster-nuclei is generated. On this basis, the ray tracing (RT) together with propagation-graph (PG) methods are utilized to emulate the reflection and scattering components of the channel transfer function (CTF) for each cluster-nuclei, respectively. Meanwhile, scattering is considered at the last bounce of each reflection path in the macro-cell downlink scenario regarding the asymmetrical obstacles distributions. Besides, the directive scattering model is used to enhance the modeling accuracy for PG. We emulate a macro-cell street scenario and provide related characterization results. Simulation results reveal that our proposal can capture the channel non-stationarities at a low computational cost while guaranteeing relatively high accuracy.

On the one hand, laparoscopic surgery as medical state-of-the-art method is minimal invasive, and thus less stressful for patients. On the other hand, laparoscopy implies higher demands on physicians, such as mental load or preparation time, hence appropriate technical support is essential for quality and suc-cess. Medical Digital Twins provide an integrated and virtual representation of patients' and organs' data, and thus a generic concept to make complex information accessible by surgeons. In this way, minimal invasive surgery could be improved significantly, but requires also a much more complex software system to achieve the various resulting requirements. The biggest challenges for these systems are the safe and precise mapping of the digital twin to reality, i.e. dealing with deformations, movement and distortions, as well as balance out the competing requirement for intuitive and immersive user access and security. The case study ARAILIS is presented as a proof in concept for such a system and provides a starting point for further research. Based on the insights delivered by this prototype, a vision for future Medical Digital Twins in surgery is derived and discussed.

In this paper, we consider a user-centric simultaneous wireless information and power transfer (SWIPT) mmWave system, where a time switching protocol is employed at users to support both energy harvesting and information decoding. To enable user-centric BS cooperation, dynamic BS clustering is used to adapt the user’s serving cluster to the channel condition. For this setup, we characterize the joint rate and energy (JRE) coverage, namely, the probability that the user can both harvest sufficient energy in a given time slot and receive the required minimum data from a given serving cluster. The analysis is challenging because of the random serving clusters as well as the correlation between the amount of harvested energy and the information rate. All analytical results are validated by Monte-Carlo simulations. Our results reveal that the proposed analytical models are accurate and efficient in the design and deployment of user-centric-SWIPT mmWave systems.
