As a UE Log Analyst, recently I performed NR capability validation where our UE supports:
NR Band n28 (700 MHz)
NR Band n78 (3500 MHz)
From the attached ELT analysis snapshot, we can clearly observe:
UE-NR-Capability IE decoding
BandNR: 78 (SCS-30kHz supported)
BandNR: 28 (SCS-15kHz supported)
MIMO Parameters per Band
CSI-RS & Beam Management capabilities
TCI-State PDSCH configurations
Max CSI-RS resources & Beam reporting support
How to Analyze NR Band Support in ELT Tool:
Open NRRC → UE-NR-Capability IE
Navigate to BandNR section
Verify:
Supported Band Numbers (n28 / n78)
Subcarrier Spacing (SCS)
MIMO & Beam Management parameters
CSI-RS configuration support
Cross-check with network deployment band to validate SA/NSA compatibility
Why This Analysis Matters?
Confirms UE hardware & modem band support
Validates SA/NSA deployment compatibility
Helps avoid field mobility issues
Supports 3CC / Carrier Aggregation planning
Reduces unnecessary drive testing cost
5G log analysis is not just about connection success — it’s about capability validation before deployment.
