[srslte-users] SRS UE connecting to commercial network

Tue Jun 11 10:31:07 UTC 2019

Hi Andre,

Thank you for the replies. Running as a superuser doesn't make a difference
in my system. Can you explain what you mean by setting scheduling
correctly? Set the log level to info for all layers means phy_lib_level =
from none to all_level or adding phy_level = all? (I am a bit confused from
the comments). I found the location of the log to be /tmp/ue.log. I looked
at the file and I didn't find anything in it. I am adding the output with
sudo at the end of the next paragraph.

Further, In the README file, it says, it has been tested for bandwidths:
1.4, 3, 5, 10, 15 and 20 MHz. I assume this is the channel bandwidth and I
need it for 20MHz. From one of the papers, I remember the srsLTE code is
set to 20MHz. How do I change it? I was not able to decode.
