Glossary (OTA)
5G NR EMF
Conducted
Center
Frequency
The specified 5G NR carrier center frequency.
Cell ID (PCI) Physical cell ID – The Primary Sync Signal and Secondary Sync Signal largely define the PCI. PCI is also
referred to sometimes as Cell ID.
SSB
Numerology
Synchronization Signal Block (SSB)
ScsCommon Subcarrier spacing common (ScsCommon)
SSB Case Synchronization Signal Block Case (SSB Case)
SSB Lmax Synchronization Signal Block (SSB Lmax) is the maximum number of SSBs within a SSB.
SSB Periodicity
(ms)
Synchronization Signal Block Periodicity (SSB Periodicity (ms))
SSB RB Offset Synchronization Signal Block Resource Block Offset (SB RB Offset)
SSB SC Offset Synchronization Signal Block (SSB SC Offset)
SSB Delta
Center (kHz)
Synchronization Signal Block Delta Center (SSB Delta Center (kHz))
Sync Corr (%) Synchronization Correlation (Sync Corr (%))
Channel Power
(dBm)
Channel power
Freq Error (Hz) Frequency error (Hz)
Time Offset
(ms)
Time Offset (ms) is one of the required EVM calculations.
PSS EVM
(%rms)
PSS EVM (%rms) is the Primary Synchronization signal for 5G NR EVM.
SSS EVM
(%rms)
SSS is the Secondary Synchronization signal for a 5G NR EVM (%rms).
PBCH DMRS
EVM (%rms)
Physical Broadcast Channel Demodulation Reference Signal for EVM (%rms).
Composite
EVM (%rms)
Composite EVM (%rms) analyzes the output of the combined signal from multiple transmit antennas.
SS-RSRP
(dBm)
Synchronization signal reference signal received power (SS -RSRP) is defined as the linear average over
the power contributions (in [W]) of the resource elements that carry secondary synchronization signals
(SS).
