Configuration

HC-2 Hardware Setup

Cables should be connected as shown in the image.

Ip address configuration (Optional)
The default configuration is static with IP address 192.168.2.15, and you can change this IP following below operations.

• Login via SSH user: user password: root123

• Edit IP configuration file with below command sudo vi /etc/netplan/01-netcfg.yaml
  Save file and exit

• To apply new configuration, use below command sudo netplan app

Provisioning of execution and configuration

Provisioning of execution and configuration for RF1

Provision

Open terminals as required (min 3 )
i. Run the command in all the terminals ssh root@192.168.2.15 pass- root123

Execution of L1 &L2 for RF1

For 4×4 Transmission

For L1
2. Perform following steps for run processes: –
i. To run L1 binary enter following command: –
-> Go to first tab of terminal and enter path for L1 cd /opt/FCC_DEV0/L1/script Some Details required for running L1
Now first open the L1_NR.cfg by using the command vi ../cfg/L1_NR.cfg
Go to the insert mode by pressing i key and edit the parameter.

To change the Sampling Rate parameter
Uncomment (Remove #) the samplingRate_kHz value according to the channel bandwidth as shown in below picture.

To assign antenna port value
Set the sdrTxSubdevSpec and sdrRxSubdevSpec should be given in the picture.
If it is not similar to configuration in the L1 config file, then make it like this:

Once done, save the file press ESC and type command :wq then press ENTER.

Now Run L1 by using this command
./runL1.sh

For L2
To run MAC_NR binary enter the following commands in second terminal

• Go to second tab and change path for MAC_NR cd /opt/FCC_DEV0/L2/src
• To edit config file of L2 refer point (c) Configuration from page number 5 (Use another terminal)
• Run L2 by using this command taskset -ac 4-7 ./MAC_NR 0
  Once done, both L1 and L2 are live. Now just press ctrl+c after at least 10 seconds on the L2 terminal. Go to the L1 terminal, comment (Add # at the starting of command) on the previous sdrTxSubdevSpec and sdrRxSubdevSpec parameter, and uncomment (Remove #) the sdrTxSubdevSpec and sdrRxSubdevSpec, which are shown in the below picture. After that, just save the file, press ESC, type command :wq then press ENTER.
  Once done, run L1 and L2. Wait for some time until “L1 is now live” is visible on the terminal, then both processes are up. Once all LEDs are glowing on RF1, you are able to take observations on the 4 TX ports.
  Note: Whenever you want to change frequency and band, you need to repeat the above process.

Configuration for RF1
Perform following steps for opening configuration file :-

1. Go to the third tab of terminal
2. Enter cd /opt/FCC_DEV0/L2/cfg for config path
3. Enter vim config.cfg to open config file in vim text editor.
4. After completion of vim command a list of parameters will appear as shown below.
   Note : When you want to change frequency according to band, first edit the config file of L2 of RF1 (above picture), then save it. After saving, first run L1 of RF1 by using ./runL1.sh and then L2 of RF1 by using taskset -ac 4-7 ./MAC_NR 0

Perform following steps to modify configuration file :-

1. Go to the insert mode by pressing i key and edit the parameter.
2. To save the file press ESC and type command :wq then press ENTER
3. If don’t want to save file, press ESC and enter command :q! then press ENTER

MIMO (multiple input, multiple output) configuration for RF1

Note : It is already defined 4×4 MIMO in config file of L1.

Troubleshooting

In any case if you are not able to do the ssh or getting trouble while accessing hardware then connect monitor through HDMI/VGA cable. You will get username window then enter Username as User and Password root123.
If you get blue screen then enter ctrl+alt+f3. Enter username as User and Password is root123.
Once the authentication done enter command ipconfig for checking the IP address.

Now First do sudo su and password – root123

If you want to change the IP then enter vi /etc/netplan/00-network-manager- all.yaml. Once you enter press insert and change the IP address mention in the below picture.

UHD UPGRADE

Prerequesit:

1. Sub_6GHz Hardware should be connected with internet
2. Command: vim /etc/resolve.conf nameserver 127.0.0.53 change it to 8.8.8.8 save and close file.
3. Now check ping google.com it’s output should be like below
64 bytes from del03s16-in-f14.1e100.net (172.217.167.46): icmp_seq=1 ttl=117 time=7.05 ms
Steps to upgrade UHD

if your are facing error something like -:
{
Reading package lists… Done
Building dependency tree
Reading state information… Done
E: Unable to locate package uhd-packages
root@phluido-NUC9i9QNX:~# apt-get purge libuhd-dev
Reading package lists… Done
Building dependency tree
Reading state information… Done
You might want to run ‘apt –fix-broken install’ to correct these.
}
run this command -: apt –fix-broken install
run below given command

1. sudo apt-get remove uhd-host
2. sudo apt-get remove –auto-remove uhd-host
3. sudo apt-get purge uhd-host
4. sudo apt-get purge –auto-remove uhd-host
   while running these commands it will ask for permission Y/n then enter Y.
   dpkg -l | grep uhd
   apt-get purge uhd-packages
   vim /etc/apt/sources.list
   deb https://ppa.launchpadcontent.net/ettusresearch/uhd/ubuntu bionic main deb-src https://ppa.launchpadcontent.net/ettusresearch/uhd/ubuntu bionic main append above two lines, sva e& close files.
   Now run command: apt-get update while updating it sometimes throws error for key then apt-key adv –keyserver keyserver.ubuntu.com –recv-keys received keys
   Now again run apt-get update run apt-get install libuhd-dev uhd-host -y run uhd_find_devices it’s output should lokk like below screen shot:

REBOOT HC-2 gNB
Note: In case you face the problem like that uhd is not found or you you just want to restart the hardware
Run the below command for rebooting the hardware
reboot -f
