Abstract: Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for accuracy measurements in UE baseband-demodulation-performance tests in new radio (NR) frequency range 2 (FR2) operations. The accuracy measurements includes, but not limited to, reference signal received power (RSRP) accuracy, reference signal received quality (RSRQ), and signal-to-noise and interference (SINR) accuracy. Various embodiments describe how to measure RSRP/RSRQ/SINR accuracies in an over-the-air (OTA) test environment in NR FR2 operations.
