“…Work in [75] shows that received power of wideband 73 GHz signals has a stationary mean over slight movements but average power can change by 25 dB as the mobile transitioned a building cornor from non-line-of-sight (NLOS) to LOS in an urban microcell (UMi) environment [88], [94]. Measurements at 10, 20 and 26 GHz demonstrate that diffraction loss can be predicted using well-known models as a mobile moves around a corner using directional antennas [95], and human body blockage causes more than 40 dB of fading [88], [94].…”

“…The definitive challenge for a 5G channel model is to provide a fundamental physical basis, while being flexible, and accurate, especially across a wide frequency range such as 0.5 GHz to 100 GHz. Recently, a great deal of research aimed at understanding the propagation mechanisms and channel behavior at the frequencies above 6 GHz has been published [3], [4], [12]- [32], [40], [60], [73], [75], [78], [81], [83], [84], [89]- [95], [101]- [111]. The specific types of antennas used and numbers of measurements collected vary widely and may generally be found in the referenced work.…”

This paper provides an overview of the features of fifth generation (5G) wireless communication systems now being developed for use in the millimeter wave (mmWave) frequency bands. Early results and key concepts of 5G networks are presented, and the channel modeling efforts of many international groups for both licensed and unlicensed applications are described here. Propagation parameters and channel models for understanding mmWave propagation, such as line-of-sight (LOS) probabilities, large-scale path loss, and building penetration loss, as modeled by various standardization bodies, are compared over the 0.5-100 GHz range.

This paper studies radio propagation mechanisms that impact handoffs, air interface design, beam steering, and MIMO for 5G mobile communication systems. Knife edge diffraction (KED) and a creeping wave linear model are shown to predict diffraction loss around typical building objects from 10 to 26 GHz, and human blockage measurements at 73 GHz are shown to fit a double knifeedge diffraction (DKED) model which incorporates antenna gains. Small-scale spatial fading of millimeter wave received signal voltage amplitude is generally Ricean-distributed for both omnidirectional and directional receive antenna patterns under both line-of-sight (LOS) and non-line-of-sight (NLOS) conditions in most cases, although the log-normal distribution fits measured data better for the omnidirectional receive antenna pattern in the NLOS environment. Small-scale spatial autocorrelations of received voltage amplitudes are shown to fit sinusoidal exponential and exponential functions for LOS and NLOS environments, respectively, with small decorrelation distances of 0.27 cm to 13.6 cm (smaller than the size of a handset) that are favorable for spatial multiplexing. Local area measurements using cluster and route scenarios show how the received signal changes as the mobile moves and transitions from LOS to NLOS locations, with reasonably stationary signal levels within clusters. Wideband mmWave power levels are shown to fade from 0.4 dB/ms to 40 dB/s, depending on travel speed and surroundings.

“…These mechanisms have shown a substantial impact on mmWaves [45], [51], [145]. Due to the short wavelengths of mmWave signals, ranging between 1 mm and 10 mm, their propagation mechanisms are drastically different from those the sub-3 GHz, and hence have to be carefully studied and modeled to understand the mmWave channel.…”

Abstract-The millimeter wave (mmWave) frequency band spanning from 30 GHz to 300 GHz constitutes a substantial portion of the unused frequency spectrum, which is an important resource for future wireless communication systems in order to fulfill the escalating capacity demand. Given the improvements in integrated components and enhanced power efficiency at high frequencies, wireless systems can operate in the mmWave frequency band. In this paper, we present a survey of the mmWave propagation characteristics, channel modeling and design guidelines, such as system and antenna design considerations for mmWave, including the link budget of the network, which are essential for mmWave communication systems. We commence by introducing the main channel propagation characteristics of mmWaves followed by channel modeling and design guidelines. Then, we report on the main measurement and modeling campaigns conducted in order to understand the mmWave band's properties and present the associated channel models. We survey the different channel models focusing on the channel models available for the 28 GHz, 38 GHz, 60 GHz and 73 GHz frequency bands. Finally, we present the mmWave channel model and its challenges in the context of mmWave communication systems design.
