“…The observations of Fig. 4 match up with the findings of [35]- [38], that the existence of rays with dedicated propagation mechanism is a function of the environment and the TX height in relation to the height of the surrounding buildings. Based on these observations, we derived a decision model for this type of scenarios with a TX height several meters above the surrounding roof tops.…”

For 5G/6G system simulations and radio planning the availability of both accurate and run-time efficient channel predictors is required. This paper presents a 3D ray tracing channel predictor, which takes into account the relevant propagation phenomena like free space propagation, reflection, scattering, diffraction and transmission. The predictor is validated by two types of measurements and the relevance of the various propagation phenomena is analyzed based on predictions in a city using real base station locations and building data. Based on these results an acceleration methodology for the search of reflected paths is derived, which is able to reduce the computation time to 40% compared to the baseline prediction.

“…Vehicle-to-infrastructure (V2I) communications, as an important component of 5G NR V2X communications, shares massive amounts of data among base stations, mobile devices, and vehicles under the coverage of infrastructure. Since accurate channel models for V2X communications are the foundation of system design and optimization, many channel models for V2X communications have been proposed [3]. Li et al [4] presented extensive measurements and analyses of propagation channels in V2I communications.…”

To acquire accurate channel characteristics for 5G New Radio (NR) vehicle-to-infrastructure (V2I) communications, in this paper, we propose a 5G passive channel measurement platform based on software defined radio devices and 5G user equipment. Different from active measurement platforms, the proposed measurement platform only requires a receiver and the channel state information reference signal (CSI-RS) periodically transmitted by the 5G commercial base stations is used as the measurement waveform. The channel impulse response can be computed based on the CSI-RS signal extracted from the received waveform and the standard CSI-RS signal generated according to the signaling information. By using the proposed 5G passive channel measurement platform, we carry out wireless channel measurement for V2I communications in typical urban scenarios. Further, based on the measurement, the small-scale channel fading characteristics including the power delay profile, the number of multipaths, the delay spread of multipaths, and the Ricean K-factor are analyzed.
