For Waveform Playback (ARB) capability.
This topic describes the settings of the Cell Parameters node when the carrier is Downlink NB-IoT.
NRS Coupled with Downlink Bitmap
Reference Signal Transmit Power (RSTP)
OFDM Symbol Transmit Power (OSTP)

Enter a value for the Cell ID. Based on this setting, the software sets the values in the Physical Layer Cell ID Group and Physical Layer Cell ID Sector cells.
Cell ID = [(3 x Physical Cell ID Group) + Physical Cell ID Sector]

Anchor Carrier: In NB-IoT, a carrier where the UE assumes that NPSS/NSSS/NPBCH/SIB-NB are transmitted.
Non-Anchor Carrier: In NB-IoT, a carrier where the UE does not assume that NPSS/NSSS/NPBCH/SIB-NB are transmitted. It is used for all unicast transmissions.

Select the power definition type for the primary cell.
The following two options are available for power definition type.
Total Power - When Total Power is selected, power reference is the Amplitude parameter on Instrument node. In this case, RSTP and OSTP are automatically calculated by the Amplitude parameter on Instrument node, the Power parameter in Component Carrier, and each carrier’s signal settings.
RSTP - When RSTP is selected, power reference is RSTP. The Amplitude parameter on Instrument node, the Power parameter on Component Carrier, and OSTP are automatically calculated by RSTP and each carrier’s signal settings. In this case, the Power parameter in Component Carrier is set as read-only.
