A maximum of 4 dedicated BWPs can be configured for a UE.
To configure multiple BWPs, add the following parameters to the gNB configuration file under "servingCellConfigDedicated":
To configure multiple BWPs, add the following parameters in the physical parameters section:
## Setup of the Configuration files ##
In the configuration file you have the option to select the 1st active BWP, the RIV and SCS of each BWP in the following way (example with 3 additional BWPs):
```
firstActiveDownlinkBWP-Id = 1; #BWP-Id
defaultDownlinkBWP-Id = 1; #BWP-Id
firstActiveUplinkBWP-Id = 1; #BWP-Id
first_active_bwp = 1;
bwp_list = ({ scs = 1; bwpStart = 0; bwpSize = 106;},
{ scs = 1; bwpStart = 0; bwpSize = 51;},
{ scs = 1; bwpStart = 0; bwpSize = 24;});
```
Each dedicated BWP must have:
```
# BWP 1 Configuration
dl_bwp-Id_1 = 1;
dl_bwp1_locationAndBandwidth = 28875; // RBstart=0, L=106 (40 MHz BW)
# subcarrierSpacing
# 0=kHz15, 1=kHz30, 2=kHz60, 3=kHz120
dl_bwp1_subcarrierSpacing = 1;
```
Find these parameters in this configuration file: "targets/PROJECTS/GENERIC-NR-5GC/CONF/gnb.sa.band78.fr1.106PRB.usrpb210.conf"
This example configures 3 additional BWPs, with IDs from 1 to 3. Find these parameters in this configuration file: "ci-scripts/conf_files/gnb.sa.band78.106prb.rfsim.neighbour.conf"

```
sudo ./nr-uesoftmodem -r 106 --numerology 1 --band 78 -C 3619200000 --rfsim --uicc0.imsi 208990000000001 --rfsimulator.serveraddr 127.0.0.1
