## Bandwidth part (BWP) ##
Bandwidth Part (BWP) is a set of contiguous Resource Blocks in the resource grid.
Parameters of a Bandwidth Part are communicated to UE using RRC parameters: BWP-Downlink and BWP-Uplink.
Parameters of a BWP are communicated to UE using RRC parameters: BWP-Downlink and BWP-Uplink.
A UE can be configured with a set of 4 BWPs in uplink (UL) and downlink (DL) direction. But only 1 BWP can be active in UL and DL direction at a given time.
A UE can be configured with a set of 4 BWPs in uplink (UL) and downlink (DL) direction (3GPP TS 38.331 Annex B.2 Description of BWP configuration options). But only 1 BWP can be active in UL and DL direction at a given time.

Find these parameters in this configuration file: "targets/PROJECTS/GENERIC-LTE-EPC/CONF/gnb.band78.tm1.106PRB.usrpn300.SCD.conf"
### NOTE:
* For changing bandwidth, 'dl_carrierBandwidth' and 'ul_carrierBandwidth' must be modified according
to the bandwidth of the BWP
* Currently only 'firstActiveDownlinkBWP-Id' is used to configure both DL and UL BWPs
