“…In the literature, several works propose novel multiple-input-multiple-output (MIMO) antennas for the 5G mobile handsets. Some of them are for mm-wave bands, such as the work presented in [45], which proposes a novel architecture distributed phased arrays based MIMO (DPA-MIMO) for 5G mm-wave cellular UE, and [46], which presents a cost-effective mm-wave cellular-Wi-Fi design methodology based on the new DPA-MIMO architecture. In addition, other works presents novel MIMO antennas for 5G mobile devices at frequency bands below 6 GHz, such as [47], which presents a low-profile wideband antenna for the MIMO application of 5G mobile handsets in the 3.3 GHz to 3.8 GHz frequency band.…”

The upcoming design and implementation of the new generation of 5G cellular systems, jointly with the multiple wireless communication systems that nowadays coexist within vehicular environments, leads to Heterogeneous Network challenging urban scenarios. In this framework, user's Radiofrequency Electromagnetic Fields (RF-EMF) radiation exposure assessment is pivotal, to verify compliance with current legislation thresholds. In this work, an in-depth study of the E-field characterization of the personal mobile communications within urban public trams is presented, considering different cellular technologies (from 2G to 5G). Specifically, frequency bands in the range of 5G NR frequency range 1 (FR1) and millimeter wave (mm-wave) bands within frequency range 2 (FR2) have been analyzed for 5G scenarios, considering their dispersive material properties. A simulation approach is presented to assess user mobile phone base station up-link radiation exposure, considering all the significant features of urban transportation trams in terms of structure morphology and topology or the materials employed. In addition, different user densities have been considered at different frequency bands, from 2G to 5G (FR1 and FR2), by means of an inhouse developed deterministic 3D Ray-Launching (3D-RL) technique in order to provide clear insight spatial E-field distribution, including the impact in the use of directive antennas and beamforming techniques, within realistic operation conditions. Discussion in relation with current exposure limits have been presented, showing that for all cases, E-Field results are far below the maximum reference levels established by the ICNIRP guidelines. By means of a complete E-field campaign of measurements, performed with both, a personal exposimeter (PEM) and a spectrum analyzer within a real tram wagon car, the proposed methodology has been validated showing good agreement with the experimental measurements. In consequence, a simulationbased analysis methodology for dosimetry estimation is provided, aiding in the assessment of current and future cellular deployments in complex heterogeneous vehicular environments.

“…Unlike the 5G mmWave massive MIMO base station design in which digital beamforming [5], or hybrid beamforming [14] with full-complexity can be afforded to use, hybrid beamforming with reduced-complexity such as DPA-MIMO is more applicable and cost-effective for the wireless UE hardware design. Moreover, the proposed DPA architecture can enable the reuse and multiplexing of both sub-6 GHz and mmWave front end modules for various application scenarios including greater carrier aggregation among 5G low bands and high bands [15].…”

Millimeter-wave (mmWave), massive multiple-input multiple-output (MIMO), are expected to play a crucial role for 5G and beyond cellular and next-generation wireless local area network (WLAN) communications. Moreover, unmanned aerial vehicles (UAVs) are also considered as an important component of next-generation networks. In this paper, we propose and present a mmWave distributed phased-arrays (DPA) architecture and proof-of-concept (PoC) designs for user equipment (UE) and unmanned aerial vehicles (UAVs) which will be used in 5G/Beyond 5G wireless communication networks. Through enabling a multistream multi-beam communication mode, the UE PoC achieves a peak downlink speed of more than 4 Gbps with optimized thermal distribution performance. Furthermore, based on the DPA topology, the UAV aerial base station (ABS) prototype is designed and demonstrates for the first time an aggregated peak downlink data rate of 2.2 Gbps in the real-world field tests supporting multi-user (MU) application scenarios.Index Terms-5G and Beyond, Millimeter-wave (mmWave), massive multiple-input multiple-output (MIMO), user equipment (UE), unmanned aerial vehicle (UAV), spatial multiplexing, beamforming, smartphone, product design.

“…I, the 3GPP suggests the use of 2 panels for each UE. However, given the importance of handset design in 5G mmWave networks [20], [21], we evaluate the end-to-end performance by also configuring two different numbers of panels (i.e., 2 or 3) at the UE. The results are reported in Fig.…”

The next generation of cellular networks (5G) will exploit the mmWave spectrum to increase the available capacity. Communication at such high frequencies, however, suffers from high path loss and blockage, therefore directional transmissions using antenna arrays and dense deployments are needed. Thus, when evaluating the performance of mmWave mobile networks, it is necessary to accurately model the complex channel, the directionality of the transmission, but also the interplay that these elements can have with the whole protocol stack, both in the radio access and in the higher layers. In this paper, we improve the channel model abstraction of the mmWave module for ns-3, by introducing the support of a more realistic antenna array model, compliant with 3GPP NR requirements, and of multiple antenna arrays at the base stations and mobile handsets. We then study the end-to-end performance of a mmWave cellular network by varying the channel and antenna array configurations, and show that increasing the number of antenna arrays and, consequently, the number of sectors is beneficial for both throughput and latency.
