“…The test zone size in the MPAC setup is defined as a geometry area where enclosed antenna systems can not distinguish the target propagation channel and emulated propagation channels in the MPAC setup [4][5][6]. The test zone size should be larger than the maximum antenna separation on the DUT.…”

“…2) Radio channels For the 4G UE OTA testing in the MPAC setups, a 2D uniform probe configuration is adopted in the literature, due to several reasons [4,8]. The scatterers in the environment are often nearby and randomly located around the UE, resulting in a less specular multipath profile.…”

“…SCME urban macro (UMa) and urban micro (UMi) channel models are selected in the standardization for 4G UE OTA testing. For 5G massive MIMO BSs, the BS is placed higher and further away from scatterers [4,8]. Therefore, it is expected that the angle profiles of the impinging power spectra at the BS side are more specular and confined in an angle region.…”

Abstract-Over-the-air (OTA) testing is seen as an essential method for evaluating 5G antenna systems, since conventional cable testing are no longer applicable. In the paper, we discussed the similarities and discrepancies of OTA testing in the multiprobe anechoic chamber (MPAC) setups for 4G user equipment (UE) antenna systems and massive multiple-input multiple-output (MIMO) base station (BS) antenna systems. Further, recent progress on OTA testing for 5G antenna systems in the MPAC setups are summarized.

3GPP TR 38.901 Channel Model

et al. 2021

View full text Add to dashboard Cite

The 3rd Generation Partnership Project (3GPP) recommends an accurate and compatible stochastic channel model for 0–100 GHz frequency band, which is useful to design, optimize, and evaluate the fifth‐generation (5G) systems. This standardized model can be acquired by generating the large‐ and small‐scale fading models. This article firstly reviews the main existing channel models suitable for millimeter‐wave (mmWave) frequency band as well as the typical channel modeling methods, i.e. the deterministic and stochastic models. Secondly, the generation procedure of stochastic channel model in the 3GPP standard (TR 38.901) is illustrated in detail. The large‐ and small‐scale fading parts are also simulated to demonstrate the effect of channel parameters on the channel characteristics. Finally, as an alternative model in the 3GPP standard, the map‐based hybrid channel model is demonstrated and analyzed. When the digital map and material parameters of obstacles are known, this model can predict the channel characteristics accurately using the ray‐tracing (RT) method.
