It is the best approach. I just checked the Group and I did see any new Post from you.

Hi Kobus,

I tried the 5G NR profile link below. 
It seems that I don't have enough permission.

I got an error message:

Not enough permission to use dataset: urn:publicid:IDN+emulab.net:powdersandbox+ltdataset+oai-nr-enb

Not sure how to proceed or have further questions about this error? Join the users group and ask a question. Be sure to include the error message in your question, and the name of your profile and experiment: 'OAI-NR-X300/hwangoai-QV52388'.

Can you please have a look?

Hongzhi,

I spoke to Manu and Aloizio just now and they explained that you
are trying to get the OAI NR code working on POWDER.

We have a version of this working, which I have shared with them before,
but it seems to have got lost along the way...

At any rate, see the profile link (and instructions) below,
which would be a good staring point for you.

Let us know if you have questions.

Thanks

Sometimes reboot the USRP solve the issue. Have you tried that?

Hi all,

 

Here are some updates about the tests on gNB and UE:

I logged on to PC752 for gNB and PC749 for UE.

I downloaded the branch develop-nr into /opt/oai/openairinterface on gNB and UE.

 

@Kirk, can we keep this branch in /opt/oai/openairinterface, otherwise we need to checkout and compile everytime?

 

1) At gNB: sudo -E ./nr-softmodem -O ../../../targets/PROJECTS/GENERIC-LTE-EPC/CONF/gnb.band78.tm1.106PRB.usrpx300.conf

 

First 2 runs are successful. (Log in gNB_x310_ok.log)

There are many 'L's, but I think it's known issue with UHD version 3.14.0.0-release.

 

Then I got an error for the third run. (log in gNB_x310_error.log)

I got following error: No USRP Device Found. (log in ue_x300.log)

 

@Florian, is the command line correct? I mean for --usrp-args "addr=192.168.30.1,type=x300"

If yes, I don’t know why it can’t find the USRP. Ping to 192.168.30.1 is ok.

Hi Hongzhi,

JC Zhu (on this thread) maintains this profile. I will discuss
updating the installed system packages, branch/code checkout,
pre-compiling, etc. to reduce bootstrap time for new experiments using
this profile.

A few other bits of info that might help:

* Set jumbo MTU on network interface

This can help with SDR performance issues. We are close to pushing
code so that this can be requested in the profile and set up
automatically on experiment nodes. In the meantime, please find the
interface that is communicating with the X300 on the gNB and UE (the
one with the 192.168.30.1 address in `ifconfig` output), and execute:

sudo ip link set mtu 9216 dev ifname

Where `ifname` is the name of the interface found in the `ifconfig` output.

* Ensure read and write kernel network buffers are large enough

If they are not large enough, you will typically see a warning from
libuhd when you run `uhd_usrp_probe`, etc. JC documents doing part of
this in the profile instructions, but there are actually two commands.
They are:

sudo sysctl -w net.core.rmem_max=24862979
sudo sysctl -w net.core.wmem_max=24862979

We will also set up sysctl to set these larger sizes at boot when we
revisit making the OS image for this profile.

* IP address of the SDR devices should be either `192.168.30.2` or
`192.168.40.2`

Running `uhd_find_devices` will quickly tell you the IPs of the
devices it is able to find. The `.1` address on these segments is
normally assigned to the interface on the PC connected to the SDR
(which is why it pings).

Best,
-Kirk

Hi Kirk,

I've done the set mtu on gNB:
sudo ip link set mtu 9216 dev ifname (the one with the 192.168.30.1 address in `ifconfig` output)

and changed the kernel network buffers as well:

sudo sysctl -w net.core.rmem_max=24862979
sudo sysctl -w net.core.wmem_max=24862979

IP address of USRP is `192.168.30.2`

But I have still the uhd::io_error issue. Log attached.

I use develop-nr branch.
Do you know if X300 works well with other branches?

Thanks,

Hongzhi

Hi Hongzhi,

 

I have this following profile for develop-nr branch.

It is precompiled, no need more configurations.

I just tested it.

So it could short reduce bootstrap time a

https://www.powderwireless.net/manage_profile.php?action=edit&uuid=0fa475f9-7d76-11e9-8a5c-e4434b2381fc

 

Following is what I run:

on 'enb1'

   

    sudo ip link set mtu 9216 dev ifname # change ifname with the usrp interface

    

    cd /opt/oai/develop-nr/cmake_targets/ran_build/build/

    

    sudo ./nr-softmodem -O /local/repository/etc/gnb.conf

 

on 'rue1'

 

    sudo ip link set mtu 9216 dev ifname # change ifname with the usrp interface

    

    cd /opt/oai/develop-nr/cmake_targets/ran_build/build/

    

    sudo ./nr-uesoftmodem --numerology 1 -r 106 --phy-test -C 3510000000 --usrp-args "addr=192.168.30.2"

 

Let us know if you have any issues.

Hi Leigh,

 

It seems there is another permission issue.

 

Your topology source contains invalid values.

Not enough permission to use dataset: urn:publicid:IDN+emulab.net:powdersandbox+ltdataset+nrUE-dev

 

Can you please have a look again?

I’ve done some tests on gNB and UE.

So I can see that

NR synchro pass.

PBCH and PDCCH are also successfully decoded.

But PDSCH CRC is not OK.

 

I am just wondering what type of connection is between 2 USRP of gNB and UE.

Connected by cable? What is attenuation used?

Or OTA?
