An LM79 report measures the performance (light) of LED-based luminaires based on specific and collective components which include drive current (mA), CCT (color temperature), watts, efficiency and distribution. LM79 requires complete luminaire testing. It does not cover external operating circuits or external heat sinks (e.g. LED chips, LED packages and LED modules). It uses absolute photometry rather than relative photometry.

I have gone through the measurement config/ report messages.I found that in meas report UE can send PCI, RSRP, RSRQ, CGI report at a time.

Will UE will send CGI report also at the same time or UE will send only when ENB request UE for the ECGI with the Report ECGI by giving pci ?
