NR Measurement Report

NR measurement report configuration

The measurement report configuration of NR is quite similar to LTE. The measurement report configuration is composed of
1. measObejct: which defines the which frequency to measure
2. reportConfig: which defines the triggering criterion, like A2/A3/A5/B1…

The major difference is beam related measurements and which can be found from reportQuantityRS-Indexes IE.

In addition to beam related measurements, from the measurement report example we can see that the serving cell-ID and serving cell PCI are reported as well.
