Correctly allocate SCC n_TimingAdvanceOffset and add configuration file for FDD Band n1 with COTS UE and B210

Correctly allocate SCC n_TimingAdvanceOffset, and make FDD work

We do not allocate any memory for n_TimingAdvanceOffset in the ServingCellConfigCommon (SCC). Therefore, it is always NULL.

In this commit, we allocate memory for n_TimingAdvanceOffset, such that a value present in configuration will be present in the SCC. Furthermore, specifying this value correctly in the configuration for FDD, we can have a successful connection in FDD.

Add FDD configuration file:

  • Band n1
  • 15 kHz SCS
  • 10 MHz BW

This configuration file is intended to be used with USRP B210 on the gNB side and was successfully tested with COTS UE (Quectel RM510Q-GL, iPhone 14 Pro)

How to run:

cd ~/openairinterface5g
source oaienv
cd cmake_targets/ran_build/build
sudo ./nr-softmodem -O ../../../targets/PROJECTS/GENERIC-NR-5GC/CONF/gnb.sa.band1.u0.52PRB.usrpb210.conf --continuous-tx
