Update TESTING_GNB_W_COTS_UE.md

parent 6cb01bd5
## Configuration Overview:
* Non Standalone (NSA) configuration : initial Control Plane established between UE and RAN eNB, then User Plane established between UE and gNB, Core network is 4G based supporting rel 15
* Commercial UE: Oppo Reno 5G
* OAI Software Defined gNB and eNB
* eNB RF front end: USRP (ETTUS) B200 Mini or B210
* gNB RF front end: USRP (ETTUS) B200 Mini or B210 (N300 will be needed for MIMO and wider BW's)
* 5G TDD duplexing mode
* 5G FR1 Band n78 (3.5 GHz)
* BW: 40MHz
* Antenna scheme: SISO

## Build and Install
General guidelines for building :
See https://gitlab.eurecom.fr/oai/openairinterface5g/blob/develop/doc/BUILD.md#building-ues-enodeb-and-gnodeb-executables
### **EPC**
for reference:
https://github.com/OPENAIRINTERFACE/openair-epc-fed/blob/master-documentation/docs/DEPLOY_HOME.md
```
sudo bash
cd /opt/hss_sim0609
./starthss_real
```
### **eNB**
```
sudo bash
cd /opt/hss_sim0609
./starthss_real
```
### **gNB**
```
sudo bash
cd /opt/hss_sim0609
./starthss_real
```
## Testing
* EPC launching (on EPC host):
```
sudo bash
cd /opt/hss_sim0609
./starthss_real
```
Open another window and:
```
sudo bash
cd /opt/ltebox/tools
./stop_ltebox
./start_ltebox
```
Note: when terminated the testing session, you shall stop the EPC by "./stop_ltebox"
* eNB launching (on the eNB host):
~/openairinterface5g/cmake_targets/ran_build/build$ sudo ./lte-softmodem -O ../../../targets/PROJECTS/GENERIC-LTE-EPC/CONF/enb.band7.tm1.50PRB.usrpb210.conf (-E)
eNB is using branch NR_RRCConfiguration patched with enb.diff
* gNB launching (on the gNB host)
~/openairinterface5g/cmake_targets/ran_build/build$ sudo ./nr-softmodem -O ../../../targets/PROJECTS/GENERIC-LTE-EPC/CONF/gnb.band78.tm1.106PRB.usrpn300.conf (-E)
Note: gNB is using branch NR_RRC_PRACH_procedures patched with gnb.diff
Status of the interoperability is as follows:
- setup of the CP in 4G
- setup of the measurements in 5G
- Random access procedure initiation by the UE in the 5G cell
- msg1, msg2, msg3 correctly exchanged and decoded
