2.3.9.2 In-Band / Guard-Band Configuration
Access: "Config" hotkey > "Physical Cell Setup" > "In-Band / Guard-Band" section.
This node configures settings for the operation modes "Guard-Band Operation" and
"In-Band Operation".
For background information, see Chapter 2.2.5, "Operation Modes" , on page 18.
LTE Bandwidth .............................................................................................................. 60

LTE Bandwidth
Channel bandwidth for the generated LTE signal.
Remote command:
CONFigure:NIOT:SIGN<i>:CELL:IBGBand:BANDwidth
LTE Control Region Size
Only for the in-band operation mode.
Configures how many OFDM symbols at the beginning of each DL subframe are used
for the LTE PDCCH. These symbols cannot be used for NB-IoT. So a larger value
reduces the NB-IoT DL throughput.
The value is signaled to the UE in the system information (SIB1-NB, eutraControlRe-
gionSize).
Remote command:
CONFigure:NIOT:SIGN<i>:CELL:IBGBand:CRSize
NRS-CRS Power Offset
Defines the power offset of the NB-IoT NRS symbols relative to the LTE CRS symbols.
For "In-Band Operation" with "Same PCI", this information is signaled to the UE in the
system information (SIB1-NB, nrs-CRS-PowerOffset).
