As of February 2020, all 5G NR development is part of the develop branch (the branch develop-nr is no longer maintained). This also means that all new development will be merged into there once it passes all the CI.
## NSA setup with COTS UE
This setup requires an EPC, an OAI eNB and gNB, and a COTS Phone. A dedicated page describe the setup can be found [here](https://gitlab.eurecom.fr/oai/openairinterface5g/wikis/home/gNB-COTS-UE-testing).
### Launch gNB
```bash sudo ./nr-softmodem -O ../../../targets/PROJECTS/GENERIC-LTE-EPC/CONF/gnb.band78.tm1.106PRB.usrpn300.conf```
### Launch eNB
```bash sudo ./lte-softmodem -O ../../../targets/PROJECTS/GENERIC-LTE-EPC/CONF/enb.band7.tm1.50PRB.usrpb210.conf```
## phy-test setup with OAI UE
The OAI UE can also be used in front of a OAI gNB without the support of eNB or EPC. In this case both gNB and eNB need to be run with the --phy-test flag. At the gNB this flag does the following
- it reads the RRC configuration from the configuration file
- it encodes the RRCConfiguration and the RBconfig message and stores them in the binary files rbconfig.raw and reconfig.raw
- the MAC uses a pre-configured allocation of PDSCH and PUSCH with randomly generated payload
At the UE the --phy-test flag will
- read the binary files rbconfig.raw and reconfig.raw from the current directory (a different directory can be specified with the flag --rrc_config_path) and process them.
### Launch gNB
```bash sudo ./nr-softmodem -O ../../../targets/PROJECTS/GENERIC-LTE-EPC/CONF/gnb.band78.tm1.106PRB.usrpn300.conf --phy-test```
### Launch UE in another window
```bash sudo ./nr-uesoftmodem --phy-test [--rrc_config_path ../../../ci-scripts/rrc-files]```
Some other useful paramters of the UE are
- --ue-fo-compensation: enables the frequency offset compenstation at the UE. This is useful when running over the air and/or without an external clock/time source
- --usrp-args: this is the equivalend paramter of sdr_addrs field in the gNB config file and can be used to identify the USRP and set some basic paramters (like the clock source)
- --clock-source: sets the clock-source (internal or external).
- --time-source: sets the time-source (internal or external).
## noS1 setup with OAI UE
Instead of randomly generated payload, in the phy-test mode we can also inject/receive user-plane traffic over a TUN interface. This is the so-called noS1 mode.
This setup is described in the [rfsimulator page](../targets/ARCH/rfsimulator/README.md#5g-case). In theory this should also work with the real hardware target although this has yet to be tested.

```
- **EPC**
for reference:
https://github.com/OPENAIRINTERFACE/openair-epc-fed/blob/master-documentation/docs/DEPLOY_HOME.md
## Configuration Files
Each component (EPC, eNB, gNB) has its own configuration file.
These config files are passed as arguments of the run command line, using the option -O \<conf file\>
The **REFERENCE** files for eNB and gNB, **used by the CI**, can be found here:
[enb conf file](../ci-scripts/conf_files/enb.band7.tm1.fr1.25PRB.usrpb210.conf)
[gnb conf file](../ci-scripts/conf_files/gnb.band78.tm1.fr1.106PRB.usrpb210.conf)
These files have to be updated manually to set the IP addresses and frequency.
**ATTENTION** : an **EXTERNAL** clock is used to sync the eNB and gNB,
whether the clock is internal or external is defined in the configuration files (!! details needed !!)
1- In the **eNB configuration file** :
- look for MME IP address, and update the **ipv4 field** with the IP address of the **EPC** server
```
////////// MME parameters:
mme_ip_address = ( { ipv4 = "**YOUR_EPC_IP_ADDR**";
ipv6 = "192:168:30::17";
active = "yes";
preference = "ipv4";
}
);
```
- look for S1 IP address, and update the **3 fields below** with the IP address of the **eNB** server
```
NETWORK_INTERFACES :
{
ENB_INTERFACE_NAME_FOR_S1_MME = "eth0";
ENB_IPV4_ADDRESS_FOR_S1_MME = "**YOUR_ENB_IP_ADDR**";
ENB_INTERFACE_NAME_FOR_S1U = "eth0";
ENB_IPV4_ADDRESS_FOR_S1U = "**YOUR_ENB_IP_ADDR**";
ENB_PORT_FOR_S1U = 2152; # Spec 2152
ENB_IPV4_ADDRESS_FOR_X2C = "**YOUR_ENB_IP_ADDR**";
ENB_PORT_FOR_X2C = 36422; # Spec 36422
};
```
2- In the **gNB configuration file** :
- look for MME IP address, and update the **ipv4 field** with the IP address of the **EPC** server
```
////////// MME parameters:
mme_ip_address = ( { ipv4 = "**YOUR_EPC_IP_ADDR**";
ipv6 = "192:168:30::17";
active = "yes";
preference = "ipv4";
}
);
```
- look for X2 IP address, and update the **4 fields** with the IP address of the **eNB** server / **gNB** server as below (notice : even if -in principle- S1 MME is not required for gNB setting)
```
///X2
enable_x2 = "yes";
t_reloc_prep = 1000; /* unit: millisecond */
tx2_reloc_overall = 2000; /* unit: millisecond */
target_enb_x2_ip_address = (
{ ipv4 = "**YOUR_ENB_IP_ADDR**";
ipv6 = "192:168:30::17";
preference = "ipv4";
}
);
NETWORK_INTERFACES :
{
GNB_INTERFACE_NAME_FOR_S1_MME = "eth0";
GNB_IPV4_ADDRESS_FOR_S1_MME = "**YOUR_GNB_IP_ADDR**";
GNB_INTERFACE_NAME_FOR_S1U = "eth0";
GNB_IPV4_ADDRESS_FOR_S1U = "**YOUR_GNB_IP_ADDR**";
GNB_PORT_FOR_S1U = 2152; # Spec 2152
GNB_IPV4_ADDRESS_FOR_X2C = "**YOUR_GNB_IP_ADDR**";
GNB_PORT_FOR_X2C = 36422; # Spec 36422
};
```
3- The frequency setting requires a manual update in the .C and in the gNB conf file:
In the C file **openair2/RRC/LTE/rrc_eNB.c:3217**
set the nrarfcn to the same value as absoluteFrequencySSB in the **gNB config file**, that is **641272** in the example below
C file :
```
MeasObj2->measObject.choice.measObjectNR_r15.carrierFreq_r15 =641272;
```
gNB config file :
```
# absoluteFrequencySSB is the central frequency of SSB
absoluteFrequencySSB = 641272;
dl_frequencyBand = 78;
# the carrier frequency is assumed to be in the middle of the carrier, i.e. dl_absoluteFrequencyPointA_kHz + dl_carrierBandwidth*12*SCS_kHz/2
dl_absoluteFrequencyPointA = 640000;
#scs-SpecificCarrierList
dl_offstToCarrier = 0;
# subcarrierSpacing
# 0=kHz15, 1=kHz30, 2=kHz60, 3=kHz120
dl_subcarrierSpacing = 1;
dl_carrierBandwidth = 106;
```
## Run and Test
The order to run the different components is important:
1- first, CN
2- then, eNB
3- then, gNB
4- finally, switch UE from airplane mode ON to OFF (ie Radio from OFF to ON)
It is recommended to redirect the run commands to the same log file (fur further analysis and debug), using ```| tee **YOUR_LOG_FILE**``` especially for eNB and gNB.
It is not very useful for the CN.
The test takes typically a few seconds, max 10-15 seconds. If it takes more than 30 seconds, there is a problem.
- **EPC** (on EPC host):
for reference:
https://github.com/OPENAIRINTERFACE/openair-epc-fed/blob/master-documentation/docs/DEPLOY_HOME.md
- **eNB** (on the eNB host):
Execute:
```
~/openairinterface5g/cmake_targets/ran_build/build$ sudo ./lte-softmodem -O **YOUR_ENB_CONF_FILE** | tee **YOUR_LOG_FILE**
```
- **gNB** (on the gNB host)
Execute:
```
~/openairinterface5g/cmake_targets/ran_build/build$ sudo ./nr-softmodem -O **YOUR_GNB_CONF_FILE** -E | tee **YOUR_LOG_FILE**
```
**ATTENTION** : for the gNB execution,
The -E option is required to enable the tri-quarter sampling rate when using a B2xx serie USRP
The -E opton is not needed when using a a N300 USRP
## Test Case
The test case corresponds to the UE attachement, that is the UE connection and its initial access in 5G, as depicted below:
**Source** : https://www.sharetechnote.com/html/5G/5G_LTE_Interworking.html
![image info](./testing_gnb_w_cots_ue_resources/attach_signaling_scheme.jpg)
The test reaches step **12. E-RAB modifcation confirmation** , eventhough not all the messages will appear in the log file.
## Log file monitoring
From the log file that is generated, we can monitor several important steps, to assess that the test was successful.
Log files examples can be found here:

***gNBlog.2291 :***
```
<X2AP-PDU>

</value>
</SgNBAdditionRequestAcknowledge-IEs>
```
- Upon reception of the sGNB Addition Request ACK, the eNB sends a new RRCConnectionReconfiguration message containing the NR Reconfiguration.
The UE replies with a Reconfiguration Complete message:
***eNBlog.1686 :***
```
[RRC] [FRAME 00000][eNB][MOD 00][RNTI 43eb] UE State = RRC_RECONFIGURED (default DRB, xid 1)
```
- The Random Access procedure of the UE to the gNB takes place:
***gNBlog.2382 :***
```

preamble 63, energy 35.7 dB, delay 6

```
- The eNB triggers the path switch procedure towards the MME, so that
the traffic can be routed now from the SGW towards the gNB on the S1-U
plane.

Eventually, step **12. E-RAB Modification Confirmation** is successfully reached
## Required tools for debug
- **Wireshark** to trace X2AP and S1AP protocols
- **Ttracer** for 5G messages
- **GDB debugger** to check function calls
## Status of interoperability
The following parts have been validated with FR1 COTS UE:
- Phone accepts the configurtion provided by OAI eNB:
this validates RRC and X2AP
- Successful Random Access Procedure:
PRACH is correctly decoded at gNB
Phone correctly receives and decodes msg2 (NR PDCCH Format 1_0 and NR PDSCH)
msg3 is transmitted to gNB according to the configuration sent in msg2, and received correctly at gNB
- Successful path switch of user plane traffic from 4G to 5G cell (E-RAB modification message):
this validates S1AP
- Downlink traffic:
PDCCH DCI format 1_1 and correponding PDSCH are decoded correctlyby the phone
ACK/NACK (PUCCH format 0) are successfully received at gNB
- On going:
validation of HARQ procedures
Integration with higher layers to replace dummy data with real traffic
- Known limitations as of May 2020:
only dummy DL traffic
no UL traffic
no end-to-end traffic possible
