“…High integration rate of the mmW transceivers and utilization of large antenna arrays challenges the traditional conducted testing that has been used in standardization of previous LTE, 3G and 2G systems. Different number of antennas from 32 [2] to 144 [3] or even 384 elements [4] have been reported in the literature. The cabling of antenna array for conducted testing would be very complex and the small physical dimensions of the array would make conducted testing unfeasible.…”

Performance of 5G New Radio millimeter wave (mmW) systems are expected to be tested over-the-air (OTA). In this paper, we use OTA measured system error vector magnitude (EVM) with varying automatic gain control, to characterize the achievable link range with 5G NR waveform. The platform used in the measurements is one of the first public 5G mmW wireless backhaul Proof of Concept systems. We show that OTA system EVM measured in an Electro Magnetic Compatibility (EMC) chamber with varying AGC correlates well with line of sight outdoor measurements. Hence, the link range of the system can be approximated by attenuating OTA signal level either with gain controls of the radio units or with attenuation material between the radio units. The key advantage of link range estimation based on OTA measurements in the EMC chamber is better repeatability and protection from random radio interference which is present in real outdoor environment.

In this paper, we propose a 60-GHz fractional-N digital frequency synthesizer aimed at reducing its phase noise (PN) at both the flicker (1/f 3) and thermal (1/f 2) regions while minimizing its power consumption. The digitally controlled oscillator (DCO) fundamentally resonates at 20 GHz and co-generates a strong third harmonic at 60 GHz which is extracted to the output while canceling the 20-GHz fundamental. The latter component is fed back to the frequency dividers in an all-digital phase-locked loop for phase detection, which comprises a pair of digital-to-time and time-to-digital converters with dithering to attenuate fractional spurs. The mechanism of flicker noise upconversion to 1/f 3 PN in the DCO is investigated, and a reduction technique is proposed. The 28-nm CMOS prototype achieves 213-277-fs rms jitter in the 57.5-67.2-GHz tuning range while consuming only 40 mW. The DCO flicker PN corner is record low at 300-400 kHz.

“…The fifth generation (5G) global deployment has been accelerated by joint efforts from both academia and industry, with millimeter-wave (mmWave) communication, massive MIMO and beamforming techniques becoming immediate reality. In particular, various promising 5G hardware components, circuits and systems have been proposed and demonstrated, from system level to device level [1]- [6]. On the other hand, recent years have also witnessed unmanned aerial vehicles (UAVs)/drone technologies advancing significantly, which has made them more affordable and accessible to civilian and commercial applications [7]- [10].…”

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.
