WIP: Addition of dedicated BWPs

Abhijith Atreya requested to merge scs_60_iisc into develop

This MR contains the following:

  1. New dedicated BWPs addition in NR_RRCReconfiguration message.
  2. Access serving cell dedicated (SCD) parameters w.r.t BWP from the gNB config file.

Transmission in --phy-test and --do-ra modes are tested with 'gnb.band78.tm1.106PRB.usrpn300.SCD.conf' config file and other config files.

To change BWP:

Change the BWP-Id in targets/PROJECTS/GENERIC-LTE-EPC/CONF/gnb.band78.tm1.106PRB.usrpn300.SCD.conf

firstActiveDownlinkBWP-Id = 1; #BWP-Id

firstActiveUplinkBWP-Id = 1; #BWP-Id

Tested for BWP-Ids 1 to 4.

The end goal of this activity is to implement Subcarrier spacing 60KHz in the NR code and also incorporate dynamic SCS switching.
