Millimeter-wave New Radio Test Zone Validation for MIMO Over-the-air Testing

Standardization efforts to define radiated metrics and test methods for verifying millimeter-wave (mmWave) new radio (NR) devices are currently ongoing. Multi-probe anechoic chamber (MPAC) method, which is capable of reproducing spatial fading channels in the zone, selected as reference solution NR device testing. It importance ensure that defined testing propagation environment zone correctly implemented. In this paper, a novel algorithm proposed determine wideband power-angle-delay profile reconstructed mmWave NR. The shown be generic (applicable both 2D 3D setup), applicable near-field far-field conditions robust (i.e. insensitive measurement distance errors).
