you could try reducing the BW of eNB to 5Mhz i.e. change as follows in srslte/enb.conf

n_prb = 25

Hello @herlesupreeth the n-prb is already set to 25 in the enb.conf.

Is there any config file you want me to share with you so you can look?

Thanks

[herlesupreeth]

I cant think of any apart from putting the PC running the eNB in max. performance mode because the below log suggests that PC is a bit slow to handle the sample sent by the SDR

2024-07-12T03:18:44.684897 [MAC ] [W] [ 4380] SCHED: Could not transmit RAR within the window (RA=4371, Window=[4374, 4384), RAR=4384

[kamgaarnold]

Ok. To put it in max performance, something specific needs to be done @herlesupreeth ?

Are you facing this type of instability?

[herlesupreeth]

Are you facing this type of instability?

Nope

You could try the following steps

- On AMD CPU machines:

sudo cpupower frequency-set -g performance

- On Intel CPU machines:

Install cpufrequtils:

sudo apt-get install cpufrequtils

Then edit the following file (if it doesn't exist, create it):

sudo nano /etc/default/cpufrequtils

And add the following line to it:

GOVERNOR="performance"

Save and exit.

Now you need to disable ondemand daemon, otherwise after you reboot the settings will be overwritten.

sudo update-rc.d ondemand disable

sudo /etc/init.d/cpufrequtils restart

Power management
Remove all power management features in the BIOS (sleep states, in particularC-states) and CPU frequency scaling (Intel SpeedStep). In some cases, you can
also do this with cpufreqtool. Also, disable hyperthreading in BIOS and make sure its turned off in Linux

1. check this using this command: watch grep \"cpu MHz\" /proc/cpuinfo
2. you must disable p-state and c-state in linux so you need to add intel_pstate=disable to the Linux boot options,
i.e GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_pstate=disable"  in /etc/default/grub, then perform update-grub. You may optionally add the following as well "processor.max_cstate=1 intel_idle.max_cstate=0 idle=poll"

Append "blacklist intel_powerclamp" to the end of /etc/modprobe.d/blacklist.conf, to blacklist the intel_powerclamp" module. If the file does not exist, create one, and add the line into it.
You also need to disable hyperthreading, CPU frequency control, C-States, P-States and any other power management from BIOS as well.

Install i7z utility to check the cpu

sudo apt-get install i7z
sudo i7z

The CPU should not change its frequency by more than 1-2 hertz and should not be any C-state other than C0

Hello @herlesupreeth this is the output after running all the steps above

[herlesupreeth]

Is your machine an with Intel or AMD CPU? If its an AMD, then you can ignore the above output. But, if its an Intel CPU then it could be that i7z does not supported your processor (honestly its not a big deal). Important point here is that if you now run eNB you should have more stability. If its is still not stable then your processor may be powerful enough

[kamgaarnold]

Hello @herlesupreeth. yeah, i still see the same issue. don't know what to do at this point. does using an RF-box fix this issue?

Thanks

[herlesupreeth]

yes, you could also you an external GSPDO clock (e.g. from Leo Bodnar GPSDO) to have more stability

[kamgaarnold]

Ok. I have a leobodnar GPS here. It's true I've tried it couple of times but it's little bit tricky to setup.

I'll give it a try again

Thanks alot

[herlesupreeth]

If you have a Leo Bodnar GPSDO then uncomment below line in enb.conf of srslte and give it a try

#device_args = clock=external

[kamgaarnold]

#device_args = clock=external

Alright Thanks I'll keep you posted.

[kamgaarnold]

@herlesupreeth i have an issue. see the image below. I kee seeing NO GPS signal. Actually, since i got this module it keeps showing no GPS signal. I Also connected the GPS on the REF IN pin of my bladeRF

[herlesupreeth]

The device_args I mentioned earlier is relevant only for USRP devices. For bladerf you need to check the SoapySDR args name for setting external clock reference

[kamgaarnold]

Ok. But I think now it is ok. I'll try and keep you posted eventhough I keep having disconnecting C-RNTI with gps

Hello @herlesupreeth

please do you have an idea of what this means "could not verify cpu0 scaling governor"?

Also by the way can you just give me a list of HW (like RF-Front end, the PC) that you used for the set up? Thanks

[herlesupreeth]

please do you have an idea of what this means "could not verify cpu0 scaling governor"?

You can ignore that since the docker container does not have access to read CPU governor. As long you have set the CPU scaling governor to "performance" on the host machine you dont have to worry about that warning

Also by the way can you just give me a list of HW (like RF-Front end, the PC) that you used for the set up?

I use USRP B210, with Leo Bodnar GSPDO, hp elitebook 655 g9, Sysmocom ISIM, OnePlus 5, iPhone 13 pro

Alright @herlesupreeth . Thanks. Do you know if the USRPb210 is the best rf-frontend in terme of stability?

[herlesupreeth]

Do you know if the USRPb210 is the best rf-frontend in terme of stability?

I wouldn't put it that way. The reason for going with USRP B210 is because it can be used with both srsRAN_4G and srsRAN_Project repo

[kamgaarnold]

Got you. Thanks. Do you know one who faced the issue I'm going through and was able to find a solution ?

Thanks

[kamgaarnold]

Hi @herlesupreeth for this rf issue on my side, I've ordered a 4G Modem UE which can be wired from the bladeRF to see how it performs.

Also when i bring up my system, I can't access the open5gs database but I can access the pyHSS opens. Please do you know anything causing this?

Also I see that the port for the open5gs is not listed here. So don't know if the port is still blocked.

Thanks

[herlesupreeth]

Also when i bring up my system, I can't access the open5gs database but I can access the pyHSS opens. Please do you know anything causing this?

you are accessing the wrong IP.. its should be 127.0.0.1:9999 (you are using 127.0.1.1)

Hi @herlesupreeth . Ok When I use 127.0.0.1, it still doesn't work for me. I open the phyHSS with either 127.0.1.1 or 127.0.0.1 as you suggested. When I check on my PC, the dockerhostip is instead 127.0.1.1. These first two images shows the ip pull for my host and the pyhss opened with 127.0.1.1.

This image shows 127.0.0.1 to open the ope 5gs which is not successful.

This image also shows how I access pyhss with the ip you suggested.

Here is my .env file

Thanks

[kamgaarnold]

Hello @herlesupreeth Please is there a way in which i can further check this? On the Hardware, i use an "intel-nuc". don't know if the port for the open5gs has been blocked.

Thanks

[kamgaarnold]

Hi @herlesupreeth. Since i am facing some stability issue with bladeRF i have purchased the USRP B210. Do you have a guide on how to bring up the USRP B210?

Thanks

[herlesupreeth]

It is all plug and play. No other instructions needed

[kamgaarnold]

@herlesupreeth ok thanks. so no need to install libsdr, or lisusb? i'll keep you posted.

Thanks

[kamgaarnold]

Hi @herlesupreeth I've been facing this issue

anyway resolve it?

When i check the path of the error, i get into the rf_uhd_imp.cc, i see the following

Thanks

[herlesupreeth]

I see that the version of UHD driver on your host is 4.7 but the one inside the docker is 4.6. its quite strange

[kamgaarnold]

Is there anything causing this issue?
