Abstract

This paper presents a systematic analysis of the signal quality measurement mechanism and the operation principles of the measurement report system in fifth-generation (5G) New Radio (NR) mobile communication systems. The physical meaning, measurement methods, and practical application of the indicators defined in the 3GPP TS 38.215 standard — RSRP (Reference Signal Received Power), SINR (Signal-to-Interference-plus-Noise Ratio), and RSRQ (Reference Signal Received Quality) — are described in detail. The signal monitoring requirements of various service types — enhanced Mobile Broadband (eMBB), Ultra-Reliable Low-Latency Communication (URLLC), and massive Machine-Type Communication (mMTC) — are comparatively analyzed. The Non-Standalone (NSA) and Standalone (SA) variants of the 5G NR network architecture, as well as the RedCap (Reduced Capability) devices introduced in Release 17, are examined in the context of signal measurement. The discrete values of the ReportInterval parameter defined in the 3GPP standard are analyzed, and the inefficiencies caused by the current static assignment practice for low-mobility IoT devices — including energy consumption, signaling overhead, and radio resource waste — are demonstrated. The difference in signal stability between stationary and mobile devices is quantitatively assessed based on RSRP and SINR variance. The analysis results substantiate the necessity of developing an adaptive ReportInterval management mechanism.
