Increase in voice and data traffic has recently prompted cellular operators to consider deploying LTE-like systems in the unlicensed spectrum as an option to meet their customer requirements. This has led to industry-proposed specifications for unlicensed band access, namely LTE enhanced Licensed Assisted Access (LTE-eLAA), LTE Unlicensed (LTEU)/MulteFire (MF). In this paper we focus on MF, which is an extension to the LTE specification that operates entirely in the unlicensed band. It employs a flexible frame format that enables adaptive allocation of subframes for uplink and downlink resources, unlike the rigid (or) fixed frame format used in eLAA. We study and evaluate the potential of a MF network in terms of its flexible resource allocation to ensure Quality of Service (QoS) guarantees to users. Exploiting MF’s flexible allocation, we propose a scheduling model that utilizes a satisfaction function which guarantees transmission opportunities to users that are close to their deadline (i.e., reward to users transmitting closer to their deadlines and penalty to users transmitting after their deadlines). Compared to eLAA our proposed MF scheduling algorithm achieves better performance for a dense user deployment. We corroborate the analysis by performing system level simulations in ns-3 and demonstrate good agreement between analysis and simulation with respect to latency and packet-drop metrics.

Modern communication systems use multiple antennas at the transmitter and receiver for increasing the user data rate and connection reliability. This comes at the cost of increased hardware and signal processing complexity. Hybrid beamformers, which are combinations of the analog and digital beamformers, offer a good trade-off between the hardware, signal processing complexity and performance. The analog beamformers operate on the radio frequency signals while the digital beamformers operate on the base-band signals. Unlike the fully digital or fully analog beamformers, the weights computation for the hybrid beamformers is more complicated and it requires a solution to a multi-parameter, non-convex optimization problem. This paper proposes a novel, simple-to-implement procedure, which addresses the drawbacks in the existing literature. The proposed beamformer design is addressed in three simple steps namely, transmit-only, receive-only and combined transmit and receive hybrid beamformers. The utility of the design procedures is illustrated in the context of the 5G massive MIMO beamformer, where the hardware complexity for a fully digital beamformer is not economically feasible. Numerical results are provided to support the theory.

In this work, we investigated the performance of single input single output (SISO) downlink channel considering 5G new radio (NR). A number of parameters such as different modulation schemes, channel coding with varying code rates, scalable numerology μ and 3GPP channel models have been considered for evaluation. In addition, the minimum mean square error-interference rejection combining (MMSE-IRC) technique for interference mitigation and bit error rate (BER) performance is analyzed and presented. We also compared the sum-rate performance of LTE and 5G NR. It is observed that MMSE-IRC receiver successfully mitigates the interferences compared to only MMSE based receiver. Simulation results also show performance improvement over various parameters like sum-rate, interference mitigation and BER compared to prior technologies i.e. 4G-LTE, WiMAX, etc.

Cyclic prefix direct sequence spread spectrum (CP-DSSS) is a recently proposed waveform that has been designed for coexistence with OFDM (orthogonal frequency division multiplexing) in the same or a pair of parallel networks. The first contribution of this paper is to present equations that reveal similarities and differences of CP-DSSS and OFDM. Furthermore, we show that the channel model of CP-DSSS reduces to that of a cyclic prefixed block-wise single carrier modulation (CP-SCM). However, unlike CP-SCM whose symbol rate is always equal to the transmission bandwidth, CP-DSSS can be adopted to any symbol rate equal to or smaller than the transmission bandwidth. This reduction in symbol rate allows CP-DSSS power spectral density to drop to an arbitrarily low level, hence, facilitates it coexistence as a secondary waveform in a network of primary users. The peak-to-average power ratio (PAPR) of CP-DSSS is also explored and a method for reducing it is proposed.

Initial deployments of 5G cellular network around the Globe has happened in Non-Standalone Mode, also known as Evolved Universal Terrestrial Radio Access (EUTRA)-New Radio (NR) Dual connectivity(EN-DC). In this mode, a User Equipment (UE) connects to one 4G Evolved Node B(eNB) that acts as a Master Node (MN) and one Next Generation 5G base station (gNB) that serves as a Secondary Node (SN). With this architecture, LTE cell becomes Master Cell Group (MCG), and NR cell becomes Secondary Cell Group (SCG). In a UE supporting EN-DC, the base station configures NR SCG addition based on NR measurement reports from UE. Due to challenges in the wireless medium, SCG addition may not be successful, and failure may happen. Frequent SCG failures would lead to unstable 5G service and would cause high power consumption in UE due to repeated NR measurements. This paper presents a technique to improve power consumption in UE and discusses different methods to handle 5G cell measurements in case of frequent SCG failures. Through extensive experiments and simulations, the proposed idea has shown a reduction in power consumption by 29.6%.

Millimetre wave (mm-wave) communication and Multiple Input Multiple Output (MIMO) systems are promising solutions to overcome the challenge possessed by the future wireless systems. Spatial Modulation (SM) techniques has the inherent potential to overcome the drawbacks of MIMO systems such as increased energy consumption, complexity and cost. Quadrature Spatial Modulation (QSM) is another type of spatial modulation technique and it helps in enhancing the spectral efficiency achieved by Spatial Modulation (SM) by transmitting additional base 2 logarithm of Nt bits and it retains all other advantages of SM. A novel Generalized QSM (GQSM) aided mm-wave MIMO structure is proposed in this paper. In order to select the antenna combinations in GQSM a virtual antenna grouping is performed. The analytical and simulated average BER of the proposed system are compared to analyse its performance. Also, the average BER performance of the proposed system outperforms the GSM aided mm-wave MIMO and QSM aided mm-wave MIMO systems.

Multi-numerology OFDM systems are a promising technique to multiplex various services and requirements for 5G and beyond. Multiplexing of multiple numerologies in a single frequency band causes the system to lose orthogonality. Due to this, a new kind of interference is introduced into the system known as inter-numerology interference (INI). In this paper, an efficient INI mitigating technique based on precoding is proposed. Simulation results show that with the proposed method, a significant reduction in INI is achieved and overall system performance is improved for multi-numerology OFDM systems.

This paper presents a high directivity beamformer for the millimeter-wave (mmWave) base station application. The beamformer is capable of generating high directivity radio beams along azimuth and elevation planes. Beamformer structure consists of a spherical constant–dielectric ($epsilon_{r}$) lens created from plastic material, while the lens is fed by multiple rectangular horn feeds that are individually connected to mmWave radio sources. The lens structure can be machined out from plastic raw material while the feed network of the beamformer can be 3D printed and metallic plated, making the proposed beamformer structure a good candidate for mass production. Prototype beamformer is developed for 28 GHz mmWave 5G communication band, while it is scalable to even higher frequency mmWave 5G bands (39 GHz) using the same synthesis approach discussed in this paper.

We have designed a 5G-capable environmental sensing network (ESN) node prototype, called Advanced Air Pollution Monitoring Device (AAPMD). The developed prototype system measures concentrations of NO2, Ozone, carbon monoxide, and sulphur dioxide using semiconductor sensors. Further, the system gathers other environmental parameters like temperature, humidity, PM1, PM2.5, and PM10. The prototype is equipped with a GPS sub-system for accurate geo-tagging. The board communicates through Wi-Fi and NB-IoT. AAPMD is also implemented with energy harvesting power management, and is powered through solar energy and battery backup. Compared to the conventional designs with Wi-Fi-based connectivity, the developed system consumes 10-times less energy while using 5G NB-IoT communication module, which makes it a very competitive candidate for massive deployment in highly polluted metro cities like Delhi and Kolkata, in India. The system can provide updated measurements of pollutant levels with controllable time granularity.
