To satisfy the increasing demands for high throughput of 5G networks, 3GPP has designed the NR-U technology allowing a cellular base station (gNB) to utilize unlicensed frequency bands. In particular, with NR-U, a gNB can operate in the 5 GHz frequency bands already used by widely deployed Wi-Fi networks. Obviously, to achieve the best performance, a gNB must use a part of the spectrum as wide as possible. However, a gNB usually cannot simultaneously transmit in one channel and receive data or perform channel access procedure in another channel because of the RF power leakage problem. To cope with this problem and fully exploit all the benefits of the unlicensed spectrum, the NR-U specification defines several multi-channel access methods. However, the specification does not provide any guidelines about the selection of the appropriate method depending on network conditions or other factors. In this paper, we survey and compare all the multi-channel access methods defined in the NR-U specification and also several proposals from the literature. We evaluate the efficiency of each method in dense network scenarios and determine in which scenarios one methods outperform the others.

The 3rd generation partnership project (3GPP) standard has introduced vehicle to everything (V2X) communi-cation in Long Term Evolution (LTE) to pave the way for future intelligent transport solutions. V2X communication envisions to support a diverse range of use cases for e.g. cooperative collision avoidance, infotainment with stringent quality of service (QoS) requirements. The QoS requirements range from ultra-reliable low latency to high data rates depending on the supported application. This paper presents a QoS aware decentralized resource allocation for V2X communication based on a deep reinforcement learning (DRL) framework. The proposed scheme incorporates the independent QoS parameter, i.e. priority associated to each V2X message, that reflects the latency required in both user equipment (UE) and the base station. The goal of the approach is to maximize the throughput of all vehicle to infrastructure (V2I) links while meeting the latency constraints of vehicle to vehicle (V2V) links associated to the respective priority. A performance evaluation of the algorithm is conducted based on system level simulations for both urban and highway scenarios. The results show that incorporating the QoS parameter (i.e. priority) pertaining to the type of service supported is crucial in order to meet the latency requirements of the mission critical V2X applications.

In this study, the use of visible light communications (VLC) is discussed as a wireless telemetry solution for the gas pipeline downhole monitoring systems. A gas pipeline environment is emulated using Zemax software where we model a cylinder of 7 inches diameter along with a light source at the beginning of the pipeline and a detector on the other end with one-inch spacing from the pipeline’s edge. The coating material of the pipeline is specified as carbon steel, and properties of methane gas are considered in the simulation as similar to the real field conditions. We then perform a non-sequential ray-tracing method on the system with varying link distances, half viewing angles, and cut-off frequencies in order to investigate the effect of these parameters on the detected rays and the power received. Through MATLAB, we derived the channel impulse responses (CIRs) of the system, and according to these values, channel characterization is made by calculating the channel DC gain, path loss, root-mean-square (RMS) delay spread, and mean excess delay spread. Based on the investigations and results, at a certain bit-error-rate (BER), the maximum achievable link distances are observed for different modulation orders.

Molecular motor communication offers several advantages over molecular communication (MC) established using randomly diffusing molecules. For instance, a motor signal renders excellent directivity and can also transfer information against the concentration gradient and fluid flow. Irrespective of the aforementioned benefits, the motor communication literature is in its nascent stage. In this paper, we derive the first hitting time (FHT) probability distribution function (PDF) of the motor signal to an absorbing node using a two-dimensional square lattice structure. The hitting probabilities and the mean pulse peak time of the motor signal are deduced from the FHT PDF. We also propose a temporal modulation scheme to establish communication between the source and destination nodes. Closed-form expression for the error rate of the proposed modulation scheme is derived. The derived analytical expressions are numerically evaluated and quantitatively verified using simulations. The numerical results illustrate the trade-off between the directed and the undirected random walks traversed by the motor signal, which is a function of the detachment probability parameter.

Microgrids are the building blocks of resilient and sustainable smart cities. In remote areas, well-designed and managed microgrids can operate as standalone mode. Since renewable energy causes more intermittency to the electricity grid, interruptions to the electricity supply due to uncertain weather condition or supply shortage to charge Electrical Vehicles (EVs) in microgrids reveals extra cost especially during the peak hours. EVs can be utilized to stand this temporary circumstances with the help of decentralized services by supplying the excess electricity which is stored in the EV batteries to other microgrids. Dynamic electricity prices which are determined by smart grids are necessary to manage and control this process. The reliability of the communication link between eNodeB’s and EVs plays an important role to ensure successful delivery of the transmitted data during data aggregation process in microgrids. In this paper, the interaction between smart microgrids (i.e. buyer) and electrical vehicles (i.e. seller) for short-term power supply, and formulate a Mixed Integer Linear Programming (MILP) to obtain the best set of EVs in order to obtain cost-aware solution. In addition, considering the EV-microgrid integration over LTE links, we demonstrate the impact of the physical downlink shared channel (PDSCH) throughput performance on the following outputs of the model: total cost, the outstanding energy and the electrical vehicle’s revenue. We simulate the throughput performance in a multiuser multiple-input multiple-output (MU-MIMO) scenario.

Non-orthogonal multiple access (NOMA) and the cooperative relaying systems are two of the promising techniques to meet requirements of future wireless networks such as high spectral efficiency and wide coverage area. On the other hand, the energy efficiency has also high priority in the applications with limited energy such as sensor networks and/or internet of things (IoTs). To this end, in this paper, we propose wireless powered cooperative relaying system with NOMA thereby increasing spectral and energy efficiency. We consider three different energy harvesting (EH) protocols (i.e., power sharing (PS), time sharing (TS) and ideal) and for all three EH protocols, we derive achievable rate for the considered system model. We validate the analysis with computer simulations and present the effectiveness of wireless powered system compared to the benchmark.

Cooperative communication systems are wireless communication systems in which user/users communicates to a destination via relay/relays. In recent years, cooperative communication has a wide interest. However, most studies do not address the power allocation part. In this paper, the effect of power allocation in cooperative transmission technique using decode and forward (DF) protocol based on virtual noise is investigated. For performance evaluation, optimum power allocation (OPA) coefficients are generated and the results of OPA are compared with equal power allocation (EPA) results for different path loss scenarios. Both theoretical and simulation results show that power allocation implementation provides better bit error rate (BER) of the proposed system. In this system using binary phase shift keying (BPSK) modulation, it is shown that full diversity gain is achieved with numerical and theoretical results obtained over Rayleigh fading channels.

This paper presents a triple-band transparent flexible antenna for both 5G and ISM applications at 2.45 GHz, 3.8 GHz, and 5.7 GHz. The miniaturized proposed antenna (30 × 30 mm2) comprises two layers of polyimide as a substrate with a dielectric constant of 3.5 and a thickness of 0.125 mm. Furthermore, a tree shape transmission line and two rounded rectangular patches use Indium Tin Oxide (ITO) as a transparent conducting film while they are proximity coupled. The patches are cut by two rounded rectangular and J-shape slots to improve the radiation efficiency of the antenna. Besides, all antenna’s parts are formed to obtain radiation efficiency > 83 % at all the resonances, the gain of 3.27 dBi, 9.47 dBi, and 4.47 dBi at 2.45 GHz, 3.8 GHz, and 5.7 GHz respectively. Besides, the antenna shows a good agreement between simulation and measured results.

In this paper, we investigate the secrecy performance of a dual-hop cooperative untrusted relay network. In this network, a source node communicates with the destination node via an untrusted fixed-gain amplify-and-forward (AF) relay node. We use destination-assisted jamming so as to keep the source and destination nodes information confidential from the relay node. Under this scenario, we derive the exact secrecy outage probability (SOP) expression, tight approximate SOP expression, and asymptotic SOP expression in the high signal-to-noise ratio regime under Nakagami-m fading channels. The analysis studied in this paper can be applicable to any AF relaying systems for fixed relay gain, and two scenarios to calculate the fixed gain are compared in terms of SOP performance. Finally, the numerical and simulation studies corroborate our analytical findings.
