User Manual 1178.5689.02 ─ 06
Parameters:
<Bandwidth>
B030 | B050 | B100 | B150 | B200
LTE cell bandwidth in MHz: 3, 5, 10, 15, or 20
B030 is only allowed for "In-Band Operation". It cannot be used
in operation mode "Guard-Band Operation".
*RST:
B100
Example:
See
Configuring Physical Cell Setup
Firmware/Software:
V3.7.40
Manual operation:
See
CONFigure:NIOT:SIGN<i>:CELL:IBGBand:CRSize
<CtrlRegionSize>
Configures the control region size for the in-band operation mode.
Parameters:
<CtrlRegionSize>
CRS1 | CRS2 | CRS3
1, 2 or 3 OFDM symbols at the beginning of each DL subframe
*RST:
CRS1
Example:
See
Configuring Physical Cell Setup
Firmware/Software:
V3.7.30
Manual operation:
See
CONFigure:NIOT:SIGN<i>:CELL:IBGBand:POFFset?
Queries the power offset of the NB-IoT NRS symbols relative to the LTE CRS symbols.
Return values:
<PowerOffset>
N6 | N4D7 | N3 | N1D7 | ZERO | P1 | P1D2 | P2 | P3 | P4 |
P4D2 | P5 | P6 | P7 | P8 | P9
Power offset in dB: -6, -4.77, -3, -1.77, 0, 1, 1.23, 2 to 4, 4.23, 5
to 9
Example:
See
Configuring Physical Cell Setup
Usage:
Query only
Firmware/Software:
V3.7.40, V3.7.50: changed usage (query only) and range exten-
ded
Manual operation:
See
CONFigure:NIOT:SIGN<i>:CELL:IBGBand:IPCI
<InbandPCI>
Selects the PCI mode for the in-band operation mode. It indicates whether the NB-IoT
cell uses the same physical cell ID as the LTE cell.
