“…In the mmWave bands, building and terrain surface height variations are significant compared to the wavelength. Therefore, several works have shown the significance of considering the diffuse scattering phenomena to obtain an accurate channel model [15,16,17]. Distributed sources can be classified as coherently distributed (CD) and incoherently distributed (ID) sources by comparing the channel coherency time and observation period [11].…”

“…Motivated by radiation theory, the authors in [14], [15] assume a certain scattering lobe for an incident ray, denoted as effective roughness approach. This approach is successfully employed in ray tracing [16]- [18], point cloud scattering [19]- [23] or propagation graph theory [24], [25]. It has been parameterized for several materials [23], [26].…”

Multipath-assisted positioning makes use of specular multipath components (MPCs), whose parameters are geometrically related to the positions of the transceiver nodes. Diffuse scattering from rough surfaces affects the observed specular reflections in the angular and delay domains. Based on the effective roughness approach, the angular delay power spectrum can be calculated as a function of location parameters, which-in a next step-could be useful to accurately characterize the position-related information of MPCs. The calculated power spectra follow reported characteristics of stochastic multipath models, i.e. Gaussian shape in the angular domain and an exponential shape in the delay domain. The resulting angular and delay spreads are in an equivalent range to values reported in literature.

“…The METIS map-based model, which was proposed to fulfill the 5G channel modeling requirements, is based on the 3D RT principle as well [11]. A few studies validating RT simulations, via comparing RT simulation results with channel measurements at 60 GHz, were reported in the literature [12][13][14][15]. In [12], measurements in a conference room are compared to a detailed model in RT.…”

“…The RT tool does not include scattering, and the RMS delay-spread power and RMS delay-received power are underestimated but show good agreement for the most dominant paths. In [13,14], a RT tool including diffuse scattering is calibrated and used to compare RT to measurements in a furnished but open indoor environment. By including diffuse scattering in RT simulations, the agreement with measurement improves on path loss, delay spread, and angular spread.…”

Ray tracing-(RT-) assisted beamforming, where beams are directly steered to dominant paths tracked by ray tracing simulations, is a promising beamforming strategy, since it avoids the time-consuming exhaustive beam searching adopted in conventional beam steering strategies. The performance of RT-assisted beamforming depends directly on how accurate the spatial profiles of the radio environment can be predicted by the RT simulation. In this paper, we investigate how ray tracing-assisted beamforming performs in both poorly furnished and richly furnished indoor environments. Single-user beamforming performance was investigated using both single beam and multiple beams, with two different power allocation schemes applied to multibeamforming. Channel measurements were performed at 28-30 GHz using a vector network analyzer equipped with a biconical antenna as the transmit antenna and a rotated horn antenna as the receive antenna. 3D ray tracing simulations were carried out in the same replicated propagation environments. Based on measurement and ray tracing simulation data, it is shown that RT-assisted beamforming performs well both for single and multibeamforming in these two representative indoor propagation environments.
