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
Synchronization Signal Block (SSB)
Numerology
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
Synchronization Signal Block Periodicity (SSB Periodicity (ms))
(ms)
SSB RB Offset
Synchronization Signal Block Resource Block Offset (SB RB Offset)
SSB SC Offset
Synchronization Signal Block (SSB SC Offset)
SSB Delta
Synchronization Signal Block Delta Center (SSB Delta Center (kHz))
Center (kHz)

Freq Error (Hz)
Frequency error (Hz)
Time Offset
Time Offset (ms) is one of the required EVM calculations.

PSS EVM
PSS EVM (%rms) is the Primary Synchronization signal for 5G NR EVM.
(%rms)
SSS EVM
SSS is the Secondary Synchronization signal for a 5G NR EVM (%rms).
(%rms)
PBCH DMRS
Physical Broadcast Channel Demodulation Reference Signal for EVM (%rms).
EVM (%rms)
Composite
Composite EVM (%rms) analyzes the output of the combined signal from multiple transmit antennas.
EVM (%rms)
SS-RSRP
Synchronization signal reference signal received power (SS -RSRP) is defined as the linear average over
(dBm)
the power contributions (in [W]) of the resource elements that carry secondary synchronization signals
(SS).
