OAI 5G NR搭建gNB和nrUE

有做这个的可以加QQ群：1097302005一起交流学习

USRP N310

安装UHD驱动[1]

我们将在GitHub上git clone UHD源码库，切换到源码库的特定版本，然后从源代码构建和安装。

第一，在home目录下新建一个文件夹名字为git-repositories

cd $HOME
mkdir git-repositories
cd git-repositories

第二, clone 源码库, 然后进入uhd文件夹.

git clone https://github.com/EttusResearch/uhd
cd uhd

第三, 切换 UHD 版本 3.15.1.1.

git checkout v3.15.1.1

第四，新建文件夹

cd host
mkdir build
cd build

第五, 创建make文件.

cmake ../

第六, 运行 make去编译 UHD.-j8表示用8个CPU核心编译，加快速度，如果是四核的CPU可以用-j4或者不用

make -j8

第七，运行基本测试，以验证构建过程是否正确完成。

make test

第八, 安装 UHD, using the default install prefix, which will install UHD under the /usr/local/lib folder. You need to run this as root due to the permissions on that folder.

sudo make install

Next, update the system’s shared library cache.

sudo ldconfig

Finally, make sure that the LD_LIBRARY_PATH environment variable is defined, and includes the folder in which UHD was installed. Usually you can add the line below to the end of your $HOME/.bashrc file:

export LD_LIBRARY_PATH=/usr/local/lib

If the LD_LIBRARY_PATH environment variable is already defined with other folders in your $HOME/.bashrc file, then add the line below to the end of your $HOME/.bashrc file to preserve your current settings.

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib

For this change to take effect, you will need to close the current terminal window, and open a new terminal window.

At this point, UHD should be installed and ready to use. Verify this by running uhd_find_devices. You should see something similar to the following.

[INFO] [UHD] linux; GNU C++ version 7.5.0; Boost_106501; UHD_3.15.0.0-0-unknown
--------------------------------------------------
-- UHD Device 0
--------------------------------------------------
Device Address:serial: 31BAF1Faddr: 192.168.10.2claimed: Falsemgmt_addr: 192.168.10.2mgmt_addr: 192.168.20.2product: n310type: n3xx

Now that UHD has been installed, we need to download the USRP FPGA images from the Ettus Research website. To do this, run the command listed below. The FPGA image files will be stored in the /usr/local/share/uhd/images folder.

   sudo uhd_images_downloader

Next, we need to write the “HG” FPGA image to the USRP N310.

   uhd_image_loader --args "type=n3xx,addr=192.168.10.2,fpga=HG"

Do not interrupt the writing program. If there is an interruption, an incomplete FPGA image will be written to flash memory, and the USRP 2974 will be bricked. To unbrick the device, you will need to write the FPGA via JTAG, and then re-write it with the uhd_image_loader utility.

Once the writing program successfully completes, reboot the USRP N310.

Verify that the FPGA image has been correctly written by running the uhd_usrp_probe utility.

UHD requires larger read and write socket buffer sizes than the default values to avoid potential overflows and underruns at high sample rates. A size of 32 MB should be sufficient. To do this, run the command listed below.

 sudo sysctl -w net.core.rmem_max=33554432sudo sysctl -w net.core.wmem_max=33554432

These settings will not persist across a reboot of the system. In order to make these settings permanent, add the following lines into the /etc/sysctl.conf file, as shown below.

   net.core.rmem_max=33554432net.core.wmem_max=33554432

Next, increase the system stack size limit, with the command below.

   sudo ulimit -s 8192

When UHD spawns a new thread, it may try to boost the thread’s scheduling priority. If setting the new priority fails, then the UHD software prints a warning to the console, as shown below. This warning is harmless; it simply means that the thread will retain a normal or default scheduling priority.

UHD Warning:
Unable to set the thread priority. Performance may be negatively affected.
Please see the general application notes in the manual for instructions.

EnvironmentError: OSError: error in pthread_setschedparam

To address this issue, non-privileged (non-root) users need to be given special permission to change the scheduling priority. This can be enabled by creating a group usrp, adding your username to it, and then appending the line @usrp - rtprio 99 to the file /etc/security/limits.conf.

   sudo groupadd usrpsudo usermod -aG usrp $USER

Then add the line below to end of the file /etc/security/limits.conf:

   @usrp - rtprio  99

You must log out and log back into the account for this settings to take effect.

Additional information about this is posted in the UHD User Manual here.

gNB搭建

基础文件下载

sudo apt-get update
sudo git clone https://gitlab.eurecom.fr/oai/openairinterface5g.git

切换到develop分支

cd ~/openairinterface5g
sudo git checkout develop
source oaienv
cd cmake_targets

第一、安装依赖：仅限于电脑之前从未安装过OAI，如果安装过就不需要了。可以采用build_oai -h 查看相关参数的说明（这一步需要较长时间）

sudo ./build_oai -I

第二、编译:使用USRP这里一定需要加-w USRP

sudo ./build_oai  -w USRP --gNB --nrUE

显示如下：

sdr@sdr-eNB1:~/openairinterface5g/cmake_targets$ sudo ./build_oai -x -w USRP --gNB
