Hi all,
I am deploying Open Air Interface 5G with USRP n310s and just want to verify
something.
So the question is - for the communication using FDD between a base station and
UE, two n310s should be synced through an external time source (such as NTP),
right?
Or should the internal clock sou
Hi all,
Is it possible for me to set the transmission power of N310 when I image the
filesystem image or something? or is there any config file that I can use?
I’m trying to deploy OAI 5G RAN using n310 and the specan does not catch
anything. I wonder if this is because the transmission power f
Hi,
I am setting up OAI 5G gNB and UE with USRP N310 (connected through 1GbE to a
desktop with the following CPU:
\- Intel(R) Core(TM) i9-7900X CPU @ 3.30GHz
and when I tried to run the UE with
```
sudo ./nr-uesoftmodem --sa --usrp-args "type=n3xx, addr=10.0.0.10" --numerology

Hi Loy,
I have a similar problem to yours.
I am trying to run the OAI 5G nr-UE binary with
```
./nr-uesoftmodem --sa --usrp-args "type=n3xx, addr=192.168.99.114" --numerology
1 -r 106 --band 78 -s 516 -C 361920 -d --ue-fo-compensation -E --ue-rxgain

```
and getting the following error
Hi Cedric,
Thanks for your response.
You are right, the packet size is way too small.. I managed to increase it to
2000 and confirmed that the MTU on interfaces of both USRP and host was already
set to 9000.
However, it still give me the “ERROR_CODE_OVERFLOW (Out of sequence error)”.

Hi Marcus,
Thanks for your response.
I did run the “rx_sample_to_file” example but did not get any timeout error.
The following is the part of output I get when I run the OAI UE:
Found USRP n310
\[HW\] device_init() sample_rate:4608
\[HW\] cal 0: freq 35.00, offset 0.0
Hi, I am using USRP N310 connected via a switch with 10Gbps interface.
I am using it to set up OAI 5G RAN but I keep getting the following message:
\[HW\] reived 16384 samples out of 23040
\[HW\] ERROR_CODE_TIMEOUT (or ERROR_CODE_OVERFLOW)
I wonder if it is a sync problem or something else.
